Domestic electrical troubleshooting services in Ireland
Professional electricians use a combination of diagnostic tools, technical know-how and safety procedures to find the cause of electrical faults in your home. Here are some of the most common fault-finding services offered by registered Irish electricians:
Tripping circuits and fuse board issues
If your circuit breakers or RCDs (residual current devices) trip regularly, there may be an issue with overloaded circuits, faulty appliances, water ingress, or wiring faults. An electrician can carry out live testing and insulation resistance checks to pinpoint the issue.
Socket and lighting faults
Dead sockets, flickering lights, or lights that won’t switch off properly can indicate poor connections, damaged wiring, or internal overheating. Electricians can test the affected circuits, isolate faults and make safe repairs.
Overheating cables and burning smells
If you notice burning smells near sockets or light fittings, it may be due to overheating wiring or overloaded accessories. These issues require urgent investigation to prevent electrical fires.
Heating cable diagnostics
For homes with electric underfloor heating or heating mats, a fault may not be visible. Electricians can use thermal imaging (thermography) and specialist resistance testing to locate breaks or defects in heating cables embedded in flooring.
Earth faults and voltage irregularities
Sometimes a fault occurs in the earthing or bonding system, which can cause metal appliances or fixtures to become live. Electricians can measure voltage drop, test earthing continuity, and make corrections to ensure safety.
Short circuits and neutral faults
Short circuits can result in fuses blowing or breakers tripping the moment a device is switched on. A full diagnostic involves checking for loose connections, damaged cable insulation, or neutral wire faults.
Cable and pipe tracing
Need to find a hidden power cable or locate a fault behind a wall or underground? Electricians can use tracing equipment to safely identify the location of live or damaged wiring, without tearing up floors or walls unnecessarily.
Thermographic inspections
Some electricians offer thermographic imaging for fault detection. This can reveal hotspots in fuse boards, cable joints, or appliances — often before they fail completely — helping you plan proactive repairs and avoid emergencies.
