Electrical safety and maintenance in Lebanon: the complete guide
Where electrical risks sit in Lebanese homes and businesses: breakers and cables, RCD protection, earthing, changeover between state power, generator and solar, solar batteries, overloaded circuits, water heaters, wet areas, old wiring, building risers, warning signs, inspections and choosing an electrician.
Lebanese installations juggle state electricity, a generator subscription and often solar batteries, usually on wiring that was never designed for today's loads. Every installation needs breakers matched to cable sizes, residual current protection, which typically trips at 30 mA in domestic 230 V systems and protects people from shock in a way ordinary breakers cannot, a tested earth, a labelled panel and a proper changeover between sources. Solar systems need quality batteries, DC protection and correct cables, since Lebanese reporting links faulty installations to fires, and there is no required certification for solar companies.
Why electrical safety in Lebanon needs special attention
Few countries ask as much of a home's wiring as Lebanon does. A typical apartment is fed by state electricity for limited hours, a private generator subscription, and increasingly a solar system with batteries and an inverter, often all connected through changeover switches added years after the original installation. Many buildings are decades old, with wiring that was never designed for today's loads: several split ACs, electric water heaters, washing machines, water pumps, and phones, laptops and routers charging around the clock. Add voltage that swings between sources, extension leads and multi-plugs running under furniture, and connections added by different people over the years, and the result is a system that can work fine for years and then fail suddenly.
Reports of fires attributed to electrical short circuits are a regular part of Lebanese news. L'Orient Today, citing the National News Agency, reported a large fire in a sponge factory in Dohat Aramoun that was likely due to an electrical short circuit, and a fire in the courtyard of a mosque in Tripoli for which initial information pointed to a short circuit. This guide explains where the risks are in Lebanese homes and businesses, what protection every installation should have, how to make generators and solar systems safe, the warning signs to act on, and how to choose an electrician.
The basics every installation needs
Circuit breakers sized for the cables
Each circuit's breaker protects the cable behind it from overheating. When breakers keep tripping, the common improvised fix is to replace them with a larger size, which removes the protection and lets the cable overheat inside the wall. A breaker that trips is telling you something; the right response is to find the cause, not to make it stop.
Residual current protection
Ordinary breakers and fuses protect cables from overload and short circuits, but they react too slowly to protect a person from electric shock. That is the job of a residual current device, or RCD, which compares the current going out and coming back and disconnects when some of it leaks to earth, for example through a person. According to RS Components' guide, in domestic 230 V installations RCDs typically disconnect when leakage reaches 30 mA, because more than this could cause a dangerous and potentially fatal shock, and they also greatly reduce the risk of electrical fires. An electronics retailer's technical guide notes that common RCDs react in less than 40 milliseconds. Many older Lebanese panels have no RCD at all; retrofitting one is among the most valuable safety upgrades available.
Earthing
An RCD and many appliances rely on a working earth connection. Without proper earthing, a fault can leave the metal casing of a water heater, washing machine or pump live without anyone knowing. Earthing should be tested, not assumed, especially in older buildings and after renovations.
A clear, labelled panel
Every circuit in the distribution board should be labelled so anyone can switch off the right one in an emergency. A panel full of unlabelled breakers, loose wires and mixed sources is a warning sign in itself.
Our electrical panel, circuit and safety device maintenance service checks breakers, RCDs, earthing and labelling.
State power, generator and solar: three sources, one installation
The most Lebanese part of any installation is the way it switches between sources. When state electricity comes, the home moves to it; when it goes, to the generator; and if there is solar, to the inverter and batteries. Done properly, this uses a correctly rated changeover switch or automatic transfer switch that makes it impossible for two sources to feed the same circuits at once, with the neutral handled correctly and each source protected. Done badly, with improvised switches, shared neutrals or sources wired together, it can back-feed into the street network, damage appliances with voltage spikes, overheat connections and endanger people working on the lines. If your home switches sources, have the changeover arrangement checked. Our generators and backup power guide explains subscriptions and changeover in detail.
Solar systems and batteries: the new fire risk
Solar has transformed how many Lebanese homes get power, but it has also brought new hazards into apartments and onto roofs. The Badil, a Lebanese outlet, reported fires and battery explosions due to faulty solar installations, noting that low-quality batteries and inverters are part of the problem, that low-cost lead-acid batteries are not built for the heavy daily charge and discharge cycles of solar systems, that high voltage can overload inverters and cause electrical fires, and that there is no required certification process for solar PV companies operating in Lebanon.
Practical rules for safer solar:
- Choose equipment on quality, not only price: batteries, inverters, cables and protection devices that match each other's ratings.
- Use the right batteries for daily cycling, installed in a ventilated, dry place away from bedrooms, fuel and flammable materials.
- Fit proper DC protection: correctly rated fuses or breakers and isolators on the panel and battery sides.
- Size the cables correctly; undersized DC cables carrying high currents overheat.
- Keep the inverter ventilated and out of direct sun, and never cover it.
- Have the installation inspected after any modification, and periodically by someone other than the person who sold it.
Our solar system installation and maintenance service installs and inspects solar systems, and our solar panel cleaning service keeps output up. Our Lebanon solar guide covers sizing by season, batteries, inverters, shared roofs and Law 318/2023 in detail.
Overloaded circuits and multi-plugs
Lebanese homes run far more equipment than their original wiring expected, and extension leads and multi-plug adaptors fill the gap. Daisy-chained multi-plugs, leads coiled under carpets, cheap adaptors that get warm, and high-power appliances such as heaters, kettles, irons and water heaters plugged into the same lead are common causes of overheating. Signs of trouble include plugs or sockets that feel warm, discoloured socket plates, a smell of hot plastic, and breakers that trip when certain appliances run together. Heavy loads such as water heaters, ovens and large ACs should have their own correctly sized circuits, and permanent equipment should not live on extension leads.
Electric water heaters
Electric water heaters are among the largest loads in a Lebanese home and one of the most common sources of electrical problems: failed thermostats that let the element run continuously, corroded elements, leaks that bring water near connections, and casings that become live when earthing is missing. A water heater should have a dedicated, correctly sized circuit, a working earth connection, RCD protection, and a timer so it does not run during expensive generator hours. If the heater trips the breaker, makes the water feel tingly, or leaks, switch it off at the breaker and have it checked.
Bathrooms, kitchens and wet areas
Water and electricity are a dangerous combination in small Lebanese bathrooms and kitchens. Sockets too close to sinks and showers, light fittings that are not rated for damp areas, extension leads in kitchens, and washing machines without earth all increase risk. Wet areas should have RCD protection, fittings rated for their location, and no portable heaters or chargers near water. Leaks from roofs, balconies or bathrooms above that reach light fittings or sockets are an electrical emergency: switch off the circuit and have it checked before using it again; our waterproofing guide covers the leak side.
Older buildings and old wiring
Many Lebanese buildings were wired decades ago, and the wiring has been extended piece by piece since. Common problems include insulation that has become brittle with heat and age, cables too small for today's loads, joints made without proper connectors and hidden behind plaster, missing earth conductors, and panels with old fuses or a mix of breakers from different eras. Rodents in ceilings and generator rooms also chew cable insulation, as our pest control guide explains. If a building is old, has been renovated in parts, or shows warning signs, a full inspection is the right first step before adding new loads such as ACs, solar systems or water heaters.
Warning signs you should never ignore
- A smell of burning or hot plastic near sockets, switches, the panel or appliances.
- Sockets, plugs or switch plates that feel warm or show brown or black marks.
- Buzzing or crackling from the panel, sockets or fittings.
- Lights that flicker or dim when appliances start, beyond normal changeover.
- Breakers that trip repeatedly, or an RCD that trips when a specific appliance is used.
- A tingling feeling when touching an appliance, tap or metal surface.
- Water near electrical fittings after rain or a leak.
- Sparks when plugging in or switching on.
If you notice any of these, switch off the affected circuit or appliance if it is safe to do so, do not keep resetting breakers, and have an electrician find the cause. If there is smoke or fire, leave, call Civil Defence and do not use water on electrical fires.
Building risers, meters and shared installations
In apartment buildings, the vertical risers that carry state electricity and generator supply to each floor, the meter boards and the shared lighting circuits are common parts of the building. Overloaded risers, loose connections at meter boards, cables from different generator operators running through the same shafts, and old stairwell wiring are recurring hazards. Building committees should have shared installations inspected, keep meter and riser rooms clean, dry and locked, and make sure cables are supported, labelled and protected rather than hanging loose in shafts. Unauthorised connections to supply lines are dangerous for everyone in the building and for the people who maintain the network.
Shops, restaurants and offices
For businesses, electrical faults mean fire risk, damaged stock and equipment, and lost trading days. Commercial kitchens combine high loads, heat, grease and water; shops run lighting, refrigeration and AC for long hours; offices fill with chargers, printers and servers. A business programme includes a documented electrical inspection, labelled panels, RCD protection, correct cable sizing for kitchen and refrigeration equipment, regular thermal checks of panels and connections under load, and a plan for safe operation on generator and solar power. Our electrical inspections, compliance checks and energy assessments service provides this for businesses.
Lighting: efficient and safe
Switching to LED lighting is one of the cheapest ways to reduce consumption during generator and battery hours, and it also reduces heat in fittings. When changing fittings, use products rated for their location, especially in bathrooms, outdoors and in false ceilings, make sure connections are made with proper connectors inside approved boxes, and do not leave transformers or drivers buried in insulation where they overheat. Our lighting installation and maintenance service covers homes and businesses.
Generator rooms and building generators
Building generators bring diesel, heat, vibration and high currents together in one room. Their electrical side needs correctly sized output cables, protected and labelled distribution, secure terminations that do not loosen with vibration, earthing, and clean, ventilated rooms free of stored junk. The fuel side and the electrical side should both be part of regular maintenance. Our generator maintenance service covers building and private generators.
Battery and UPS systems inside apartments
Before rooftop solar became common, many Lebanese apartments installed an inverter with batteries that charge from state electricity or the generator and power lights and the router during cuts. These systems are still everywhere, often in a corner of the kitchen, a cupboard or under the stairs. Lead-acid batteries can release hydrogen while charging, so they need ventilation and should never be sealed in a closed cupboard or placed near flames, heaters or gas cylinders. The inverter needs airflow, the battery terminals should be covered and tight, cables should be sized for the battery current, and the system should have its own protection. A swollen, leaking or very hot battery should be disconnected and replaced, not kept in service.
Chargers, power banks, e-scooters and e-bikes
Lebanese homes charge more batteries than ever: phones, laptops, power banks, rechargeable lights and fans, and increasingly e-scooters and e-bikes. Lithium batteries are safe when they and their chargers are good quality and undamaged, but damaged, counterfeit or overheated batteries can catch fire. Use the charger designed for the device, charge on hard surfaces rather than beds or sofas, do not leave large batteries charging unattended overnight, keep e-scooters and e-bikes out of escape routes such as entrances and stairwells, and stop using any battery that is swollen, damaged or unusually hot.
Winter heaters
When the weather turns cold, electric heaters add one of the heaviest loads of the year to Lebanese circuits, often through extension leads and multi-plugs. Plug heaters directly into a wall socket, never into a multi-plug, keep them well away from curtains, beds and furniture, do not dry clothes on them, and switch them off when leaving the room or going to sleep unless they are designed for unattended use. If the breaker trips whenever a heater runs with other appliances, the circuit is overloaded and needs attention, not a bigger breaker.
Surges and lightning in mountain homes
Mountain homes are more exposed to lightning, and long overhead supply lines carry surges into houses. Surge protection devices in the panel, correct earthing and, for exposed buildings, a lightning protection assessment reduce the risk of damage to electronics, inverters and AC boards. During thunderstorms, unplugging sensitive equipment that is not protected is a sensible precaution.
Balconies, gardens and outdoor lighting
Outdoor sockets, garden lighting, water fountains and balcony fittings sit in rain, sun and dust. They need weatherproof enclosures rated for outdoor use, RCD protection, cables protected from sun damage and mechanical harm, and connections inside sealed boxes. Extension leads run out to balconies or gardens for pumps and tools should be outdoor-rated and never left lying in water.
Children and electrical safety
Young children explore sockets, cords and chargers. Socket covers or shuttered sockets, keeping cords and chargers out of reach, not leaving chargers plugged in without a device, keeping heaters and fans stable and out of reach, and making sure bathrooms have RCD protection all reduce the risk. Teach older children never to touch switches with wet hands and to tell an adult about sparks, smells or damaged cords.
Saving power reduces electrical risk
Every unnecessary load on a Lebanese circuit costs money on the generator bill and adds heat to cables and connections. LED lighting, timers on water heaters, switching off equipment at the wall instead of leaving it on standby, inverter AC units and staggering heavy appliances all reduce both consumption and electrical stress. Our Lebanon AC guide explains how amperage limits work on generator subscriptions.
Know where to switch off
Every adult in the home should know where the main switch and the panel are, how to switch off the generator and solar supply as well as state electricity, and which breaker controls the water heater and the AC units. Keep a torch near the panel, keep the area in front of it clear, and keep the electrician's number where everyone can find it. In an emergency, those few seconds matter.
Renting or buying: electrical questions to ask
Before signing a lease or a purchase, a short electrical check saves expensive surprises. Ask how many amperes the generator subscription provides and whether it can be increased, whether state electricity and generator supply switch automatically or manually, whether there is a solar system and who owns and maintains it, how old the wiring and panel are, whether there is an RCD and an earth connection, and whether the water heater and ACs have their own circuits. Look at the panel itself: labelled breakers, no loose wires and no signs of burning are good signs. For rentals, agree in writing who is responsible for electrical repairs, and photograph the panel and any visible problems at move-in.
Electrical work during renovation
Renovation is the moment to fix wiring properly, while walls and ceilings are open. Plan circuits for how the home will actually be used: dedicated circuits for the water heater, oven and each large AC, enough sockets that extension leads are not needed, RCD protection, earthing to every circuit, and space in the panel for future solar or battery connections. Use proper conduits and junction boxes rather than burying joints in plaster, keep a drawing or photographs of where cables run before walls are closed, and test the installation before handover. Doing this once is far cheaper than chasing faults through finished walls later.
Electrical fires: what to do
- If it is safe, switch off the power at the panel or main switch, including generator and solar supply.
- Never use water on an electrical fire or on equipment that may still be live.
- Use a suitable extinguisher only if the fire is small and you have a clear way out.
- Leave the building, close doors behind you if you can, and call Civil Defence.
- Do not go back inside, and do not restore power until an electrician has inspected the installation.
A suitable fire extinguisher near the kitchen and the panel, smoke detectors in corridors and bedrooms, and a clear escape route are inexpensive measures that make a real difference.
Clinics, schools and places with vulnerable people
Where children, patients or elderly people spend the day, electrical safety needs a higher standard: RCD protection throughout, regular inspection with written reports, careful management of chargers, heaters and extension leads, emergency lighting that works during power cuts, and a clear plan for switching between state power, generator and solar without interrupting critical equipment. Facility managers should keep the inspection reports on file and act on their findings promptly.
Kitchens: ovens, hobs and small appliances
Lebanese kitchens combine some of the heaviest electrical loads in the home with heat, steam, grease and water. Electric ovens and hobs need their own correctly sized circuit and a proper connection unit, not a plug in a shared socket. Kettles, toasters, microwaves, air fryers and dishwashers draw high currents for short periods; running several at once from the same socket or multi-plug is a common cause of overheated plugs. Keep appliances and cables away from the sink and hob, clean grease from around sockets and switches near the cooker, replace any appliance with a damaged cord, and never pull a plug out by its cable. Where the kitchen also houses an inverter, batteries or a gas cylinder, keep them well apart and ventilated.
Emergency lighting and power cuts
Sudden cuts are part of daily life, and how a home or building copes with them is an electrical safety question. Rechargeable emergency lights on stairwells and in corridors, battery-backed lighting in the home, and a torch near the panel prevent falls in the dark. In buildings, stairwell lighting on the generator or on a protected battery circuit keeps escape routes usable. Avoid candles where possible; if they are used, never leave them unattended or near curtains.
Energy assessments for homes and businesses
An energy assessment looks at where electricity is going: which appliances run during generator hours, which circuits carry the heaviest loads, how much the water heater and ACs consume, and where solar output is lost. For a household paying generator tariffs, or a business running refrigeration and AC for long hours, the findings often pay for the assessment quickly through timers, load shifting, efficient lighting and better use of solar. Our inspections and energy assessments combine safety findings and consumption advice in one report.
A simple monthly check you can do yourself
Most electrical problems give warning before they become dangerous, and a few minutes a month is enough to catch many of them. Without opening anything, walk through the home and check:
- Press the test button on each RCD; it should trip immediately. If it does not, call an electrician.
- Touch the front of the panel, sockets behind heavy appliances and multi-plugs in use; none should feel warm.
- Look for brown marks on socket plates and plugs, cracked covers and damaged cords.
- Listen at the panel for buzzing or crackling.
- Check that the battery and inverter area is ventilated, dry and clear, and that no battery is swollen or hot.
- Check ceilings and walls near fittings for any sign of water.
Write down anything unusual with the date. A short note like this helps an electrician find intermittent faults quickly, and it builds a record of the installation over time.
Air conditioners and the electrical installation
Split ACs are usually the heaviest continuous loads in a Lebanese home, and many were added long after the original wiring. Each large unit should have its own circuit with a breaker and cable sized for its rated current, a voltage protector suited to the unit, and a proper earth. Outdoor units on balconies need weatherproof isolators and cables protected from sun and water. When adding a new AC, check the circuit and panel first rather than tapping into the nearest socket. Our Lebanon AC guide explains voltage protection and generator limits for AC units.
The same applies to water pumps, which start against pressure and draw a surge every time they switch on: give them their own protected circuit, keep their electrical connections dry and enclosed, and check that the pump controller is not cycling the motor on and off constantly because of a leak or a faulty pressure switch.
What a professional electrical inspection covers
- Panel: breaker sizes against cable sizes, RCD presence and test, condition of busbars and terminals, labelling.
- Earthing: continuity and earth connection measured, not assumed.
- Changeover: the arrangement between state electricity, generator and solar, and protection against back-feed.
- Circuits: insulation condition, overloaded circuits, heavy loads on suitable dedicated circuits.
- Sockets and switches: loose or overheated fittings, damaged plates, wet-area fittings.
- Solar and batteries: DC protection, cable sizing, battery location and ventilation, inverter condition.
- Thermal check: where possible, panels and key connections checked under load for hot spots.
- Written report: findings, priorities and recommended actions, with photos.
When to have an inspection
- Before buying or renting a property.
- Before adding major loads: ACs, water heaters, solar systems or EV charging.
- After any warning sign, water leak near electrics or fire scare.
- After renovations or when wiring has been extended by different people.
- Periodically for businesses, rental properties and older buildings.
Common electrical mistakes in Lebanon
Upsizing breakers to stop tripping
It removes the protection and lets cables overheat inside walls.
No RCD
Ordinary breakers do not protect people from shock.
Improvised changeover
Sources wired together can back-feed, spike and overheat.
Cheap solar batteries and cables
Mismatched or undersized components are a recurring cause of solar fires.
Living on extension leads
Permanent heavy appliances need proper circuits.
Ignoring warm sockets and burning smells
These are early warnings, often weeks before a fire.
How to choose an electrician in Lebanon
- Experience with Lebanese conditions: generators, changeover, solar and voltage problems are the norm.
- Testing equipment: an electrician who measures earth, insulation and RCD trip, rather than guessing.
- Correct materials: breakers, RCDs, cables and connectors of known quality and correct ratings.
- Written quotation and report with what was found and what was done.
- Willingness to say no to unsafe shortcuts, such as upsizing breakers or skipping earthing.
- Related trades: a company that also handles AC, solar, generators and waterproofing can deal with root causes.

Frequently asked questions
What is an RCD and do I need one in Lebanon?
A residual current device disconnects the supply when current leaks to earth, for example through a person. In domestic 230 V installations it typically trips at 30 mA. Ordinary breakers protect cables, not people, so an RCD is one of the most important safety devices a Lebanese home can have.
Why does my breaker keep tripping?
Usually because a circuit is overloaded, an appliance has a fault, or there is a short circuit or earth leakage. Replacing the breaker with a larger one removes the protection; the cause should be found and fixed.
Is it dangerous to switch between state power, generator and solar?
It is safe when done with a correctly rated changeover or automatic transfer switch that prevents sources from feeding the same circuits at once. Improvised connections can back-feed, cause voltage spikes and overheat.
Can solar batteries catch fire?
Lebanese reporting has linked fires and battery explosions to faulty solar installations, low-quality batteries and inverters, and overloads. Quality components, correct DC protection and cables, and a ventilated battery location reduce the risk.
Is there certification for solar companies in Lebanon?
According to The Badil, there is no required certification process for solar PV companies operating in Lebanon, so checking the installer's experience, equipment and references matters.
Why do my sockets get warm?
Warm sockets or plugs usually mean a loose connection, an overloaded socket or multi-plug, or a damaged fitting. Stop using it and have it checked; it is an early warning of overheating.
Are multi-plug adaptors safe?
Good-quality multi-plugs are fine for low-power devices. Daisy-chaining them, running heaters or water heaters on them, or hiding them under carpets causes overheating.
Why does my water heater trip the electricity?
Common causes are a failed element, a faulty thermostat, water reaching connections or an earth fault. Switch it off at the breaker and have it checked before using it again.
Do I need earthing in my apartment?
Yes. Earthing allows protective devices to work and prevents appliance casings from becoming live during faults. It should be measured, especially in older buildings.
What should I do if water leaks near lights or sockets?
Switch off the affected circuit at the panel if it is safe to do so, keep away from wet fittings, and have the circuit checked before using it again.
What are the warning signs of an electrical problem?
Burning smells, warm or discoloured sockets, buzzing panels, flickering lights, breakers tripping repeatedly, tingling from appliances, sparks and water near fittings.
How often should a Lebanese home have an electrical inspection?
Before buying or renting, before adding major loads such as ACs or solar, after any warning sign or leak, after renovations, and periodically in older buildings and rental properties.
Who is responsible for building risers and meter boards?
They are common parts of the building, so the building committee should arrange inspection and maintenance and keep riser and meter rooms clean, dry and locked.
Can rodents cause electrical fires?
Yes. Rodents chew cable insulation in ceilings, shafts and generator rooms, which can cause short circuits. Pest control and cable protection both help.
Does Power Zone provide electrical services in Lebanon?
Yes. Power Zone provides electrical installation and repairs, panel and safety device maintenance, inspections, lighting, solar systems and generator maintenance in Lebanon.
How do I book an electrical inspection with Power Zone?
