Water leaks, flooding, or condensation causing earth leakage and RCD tripping in bathrooms, kitchens, or following storm damage. We make safe and restore full protection.
What We Do
Power Loss & Tripping Circuit Specialists
Power loss and tripping circuits are among the most common electrical emergencies in homes and businesses across Sussex. Whether your RCD has tripped and won't reset, you've lost power to part of your property, or your entire supply has gone down, our qualified engineers carry the test equipment needed to find and fix the problem fast.
Modern consumer units are designed to protect your installation by disconnecting power when a fault is detected,but when a breaker or RCD trips repeatedly, it signals an underlying fault that needs professional diagnosis. Common causes include earth leakage, overloaded circuits, short circuits, damaged cables, and faulty appliances.
Our engineers use insulation resistance testers, loop impedance testers, and RCD test equipment to systematically narrow down the fault location,even when the problem is intermittent or hard to reproduce. We aim to carry out a permanent repair on the first visit and issue a full certificate on completion.
We respond to power loss and tripping circuit emergencies across domestic homes, commercial premises, and landlord properties throughout East and West Sussex,available 24 hours a day, 7 days a week.

Common Questions
Frequently Asked Questions
Lost Power or
Circuits Tripping?
Don't leave a power loss or tripping circuit unresolved. Our qualified engineers are available right now,24 hours a day, 7 days a week across East and West Sussex.
Why Choose Us
Qualified Engineers, Permanent Repairs
Not all electrical contractors are equipped to diagnose complex power loss and tripping faults. Our engineers hold 18th Edition qualifications and carry professional test instruments on every job,not just a screwdriver and a fuse.
We don't guess. We use earth loop impedance testing, insulation resistance measurement, and RCD performance testing to identify the root cause rather than simply resetting the breaker and hoping it holds.
Every repair we carry out is accompanied by the relevant electrical certification,giving you proof of safe, compliant work for insurance, letting, or resale purposes.
We are available 24 hours a day, 7 days a week across East and West Sussex,with a typical response time of under 45 minutes to most areas.
Fault Diagnosis
What Causes Circuit Tripping & Power Loss?
Understanding the root cause is the first step to a lasting fix. Our engineers use professional test equipment to accurately diagnose each fault type before any repair begins, ensuring the problem is resolved properly rather than temporarily masked.
Overloaded Circuit
The Cause
Too many high-draw appliances running simultaneously on a single circuit exceeds the MCB rating, causing it to trip as a protective measure.
How We Resolve It
We measure the total load on the affected circuit, identify the highest-draw appliances, and either redistribute the load across circuits or upgrade the circuit rating and wiring where the existing cable cannot safely carry the demand.
Faulty or Deteriorating Appliance
The Cause
An internal fault in a plug-in or hard-wired appliance creates earth leakage current, causing the RCD to trip the moment the appliance is switched on or under load.
How We Resolve It
We isolate each circuit and test appliances individually using insulation resistance and earth leakage testing. Once the faulty appliance is confirmed, we advise on safe disconnection and whether the wiring itself requires any remedial work.
Damaged or Degraded Cable Insulation
The Cause
Cable insulation that has cracked, dried out, or been physically damaged loses its ability to contain current safely. This allows leakage to earth, triggering the RCD.
How We Resolve It
We carry out insulation resistance testing across all affected cables to measure degradation. Cables that fall below the minimum acceptable resistance are replaced or re-routed, with full continuity and polarity testing completed before power is restored.
Water Ingress or Condensation
The Cause
Water entering a socket, junction box, fitting, or consumer unit dramatically reduces insulation resistance and triggers earth leakage, causing persistent RCD tripping.
How We Resolve It
We locate the point of ingress, isolate the affected circuit, and allow or facilitate drying before retesting insulation resistance. All compromised accessories, fittings, and consumer unit components are replaced to restore safe, compliant operation.
Short Circuit
The Cause
A short circuit occurs when a live conductor makes direct contact with a neutral or earth conductor, creating a sudden surge of current that causes the MCB or fuse to operate immediately.
How We Resolve It
We disconnect the circuit and use continuity and loop impedance testing to identify the point of contact. The fault is repaired, cables re-terminated or replaced as needed, and the circuit is fully retested before reinstatement.
Loose or Corroded Connections
The Cause
Connections that have worked loose over time, or terminals affected by corrosion, can create resistance hotspots and intermittent earth faults that cause nuisance tripping without a consistent pattern.
How We Resolve It
We carry out a systematic inspection of all accessible terminations, junction boxes, and accessories on the affected circuit. All loose or corroded connections are remade to the correct torque specification using appropriate terminals and materials.
Wiring a New Appliance Incorrectly
The Cause
DIY wiring of cookers, showers, or other hard-wired appliances often results in reversed polarity, incorrect earthing, or undersized cables that cause immediate or intermittent tripping.
How We Resolve It
We disconnect and inspect the installation, test polarity, earth continuity, and insulation resistance, and rewire the appliance connection to the correct standard. A Minor Works Certificate is issued confirming compliance.
Nuisance or Spurious RCD Operation
The Cause
Some modern equipment, such as LED drivers, variable speed drives, and certain IT equipment, produces high-frequency leakage currents that accumulate across a circuit and cause the RCD to operate without a true earth fault.
How We Resolve It
We identify the equipment causing the cumulative leakage using specialist test instruments, review the circuit protection in place, and where appropriate recommend RCBO protection for individual circuits to prevent one item affecting the whole board.
Blown Main Service Fuse or Cut-Out
The Cause
A fault on the supply side of the meter or a prolonged overload can blow the main service fuse, resulting in a total loss of power that cannot be resolved by resetting the consumer unit.
How We Resolve It
We confirm the main fuse has operated and liaise with the District Network Operator (DNO) to arrange reinstatement. In the meantime, we carry out any necessary remedial work to the installation to ensure it is compliant and safe for supply restoration.
Worn or Faulty Protective Device
The Cause
MCBs, RCDs, and RCBOs have a finite operational life. A protective device that has operated many times, or one that has suffered internal damage, may trip at a lower threshold than its rated value or fail to reset correctly.
How We Resolve It
We test the operating characteristics of the suspect device using calibrated RCD and loop impedance test equipment. Devices that operate outside their rated parameters are replaced with new components of the correct type, rating, and breaking capacity.
