Tripping Circuits RCD's, MCB's, RCBO'S & AFDD's
When circuits start tripping, JS Emergency Electricians provides a fast and reliable fault finding service to quickly identify and resolve the issue safely.
With over a decade of hands on experience, we specialise in diagnosing all types of tripping faults including RCD trips, MCB trips, RCBO faults and AFDD activations. Whether the issue is caused by a faulty appliance, damaged cable, insulation breakdown, water ingress, overloaded circuits, or a high resistance connection, we have the knowledge and equipment to pinpoint the exact cause.
Our fully qualified electricians are on standby and ready to be dispatched immediately, aiming to reach you within the hour, 24 hours a day, 7 days a week.
Using advanced fault finding techniques, we systematically isolate circuits, disconnect equipment, and carry out insulation resistance testing using professional electrical test instruments.
This allows us to determine whether the fault lies within the fixed wiring or connected appliances. We can split ring circuits, test individual legs, check protective devices, and trace faults within hidden wiring without unnecessary disruption.
Once the fault has been located, we carry out efficient and effective repairs to restore power and eliminate the cause of the tripping. Whether it involves repairing a damaged cable, replacing a faulty protective device, or resolving a wiring issue, we ensure your installation is left safe, compliant, and fully operational.
Whether it’s late at night, early morning, or a bank holiday, you can rely on us for expert fault finding and tripping fault repairs carried out properly the first time.

Fault Finding on RCD's & RCBOS
When your electrics are repeatedly tripping, JS Emergency Electricians provides a fast and reliable service to identify whether the issue is with your protective devices or the wiring itself.
With years of hands on experience, we carry out thorough testing on RCDs and RCBOs to determine if they are operating correctly or if they are faulty and causing nuisance tripping. In many cases, a worn or overly sensitive device can trip without a real fault, which is why proper testing is essential before any unnecessary work is carried out.
Our fully qualified electricians are on standby and ready to be dispatched immediately, aiming to reach you within the hour, 24 hours a day, 7 days a week.
Using professional electrical testing equipment, we perform RCD trip time testing, ramp testing, and functional checks to confirm whether the device is responding within the correct parameters. At the same time, we test the wiring using insulation resistance testing and circuit checks to identify any underlying faults such as damaged cables, moisture ingress, or insulation breakdown.
By separating the installation and testing both the protective devices and the wiring individually, we can accurately determine whether the fault is coming from the consumer unit or somewhere within the circuit.
This avoids guesswork and ensures the correct repair is carried out first time.
Whether it’s a faulty RCBO, a sensitive RCD, or a hidden wiring fault, you can rely on us to diagnose the issue properly and restore your electrics safely and efficiently.
Tripping AFDD Device's
When an AFDD is tripping, it’s usually a sign of a potentially dangerous fault such as arcing within the circuit, and it’s important to identify the exact cause rather than simply resetting the device or replacing parts unnecessarily.
We specialise in diagnosing AFDD trips quickly and accurately, ensuring the underlying issue is properly located and resolved. Whether the fault is caused by loose connections, damaged cables, degraded insulation, or arcing from worn accessories or appliances, our electricians can pinpoint the problem and make the installation safe again.
Our approach involves isolating the affected circuit and carrying out detailed testing using professional fault finding equipment, alongside visual inspection of all accessible points.
We test the wiring and connections to identify signs of arcing, high resistance joints, or insulation breakdown that may not be visible to the eye.
By systematically checking sockets, switches, and connections, and dividing the circuit where necessary, we can narrow down exactly where the AFDD is detecting the fault.
This method allows us to accurately locate hidden issues within the installation without unnecessary disruption, ensuring repairs are precise, cost effective, and carried out to a high standard so the circuit can be safely restored and the AFDD operates correctly without nuisance tripping.
Weird or Burning Smells
When you notice a burning smell coming from your electrics, it’s a clear warning sign that something is overheating or beginning to fail, and it should never be ignored.
We specialise in tracing the source of burning smells quickly and safely, ensuring the issue is identified before it develops into a serious hazard such as an electrical fire. Whether the smell is coming from a socket, switch, fuse box, or hidden wiring, our electricians can locate the fault and make the installation safe.
Burning smells are often caused by loose connections, overloaded circuits, damaged cables, failing accessories, or thermal damage within the wiring. In many cases, the issue may not be immediately visible, which is why proper fault finding is essential rather than guesswork.
Our process involves isolating the affected circuit and carrying out a combination of visual inspections and electrical testing using professional equipment.
We check for signs of heat damage, discolouration, melted insulation, and high resistance connections that can cause overheating over time.
By testing and inspecting each point on the circuit and narrowing down the affected area, we can accurately locate the source of the burning smell, even if it’s hidden behind walls or within fittings. This allows us to carry out targeted repairs, prevent further damage, and ensure your electrics are safe, reliable, and fully restored to proper working order.
SAFETY
Why Experience matters...
Our electricians are highly experienced in diagnosing faults related to RCDs, RCBOs, MCBs, and AFDDs, and we deal with these types of issues every single day. Whether your fuse box is tripping intermittently or cutting power completely, we have the knowledge and hands on experience to quickly identify what’s causing the problem and put it right.
Each device protects your installation in a different way, which means faults can vary from earth leakage issues on RCDs, combined protection faults on RCBOs, overloads and short circuits on MCBs, to dangerous arc faults detected by AFDDs. Understanding how each one operates is key to accurately diagnosing the issue rather than guessing or replacing parts unnecessarily.
We use a structured fault finding approach, carrying out insulation resistance testing, continuity testing, and live diagnostics where required. By isolating circuits, splitting ring circuits, and testing individual sections, we can determine whether the fault lies within the wiring, an appliance, or the protective device itself.
With years of experience and advanced testing equipment, we’re able to locate faults quickly, minimise disruption, and carry out effective repairs. Our goal is always to restore power safely, ensure your installation is fully protected, and prevent ongoing nuisance tripping or recurring electrical issues.
