Why does my RCD keep tripping?

An RCD usually keeps tripping because it is detecting current leaking to earth. Common causes include a faulty appliance, water ingress, damaged cable, neutral-to-earth faults, or a problem on one circuit in the consumer unit. Entigen uses proper test equipment and step-by-step isolation to trace RCD faults across Kettering and Northamptonshire.

Is a tripping RCD dangerous?

A tripping RCD should be treated as a warning sign, not an inconvenience. The RCD is disconnecting power because it has detected a fault condition that could present a shock or fire risk. If it trips repeatedly, leave the affected circuit off and arrange electrical fault finding before continuing to reset it.

Can I reset the RCD myself?

You can try resetting an RCD once after unplugging appliances on the affected circuit. If it trips again immediately, trips repeatedly, or you notice burning smells, heat, water damage or damaged accessories, do not keep resetting it. A Kettering electrician should test the circuit and identify the cause before it is re-energised.

How long does it take to diagnose a tripping RCD in Kettering?

Many RCD faults can be narrowed down within the first visit, and straightforward appliance or circuit faults are often identified quickly. More complex faults, such as intermittent moisture, hidden cable damage or neutral-to-earth faults, can take longer because each circuit and accessory needs to be isolated and tested safely.

Do you charge a callout fee for RCD fault finding in Kettering?

Entigen confirms the cost before attending any RCD fault finding job in Kettering or the surrounding Northamptonshire area. We explain what is included in the initial diagnosis and, if repair work is needed, provide a clear quotation before carrying out additional work.

What's Happening

Why Is My RCD Tripping?

A constantly tripping RCD is one of the most disruptive electrical faults you can have. It usually points to a deeper issue — a faulty appliance, damp in a fitting, damaged cable, or a wiring fault hidden somewhere in the circuit.

Rather than guess or keep resetting it, it needs a proper diagnostic. At Entigen, we specialise in accurate electrical fault finding across Kettering, Barton Seagrave, Burton Latimer and surrounding areas. Many straightforward RCD faults can be narrowed down quickly with proper test equipment and step-by-step isolation.

Common Causes of a Tripping RCD

Faulty appliances — kettles, washing machines, dishwashers and garden tools are among the most common culprits for nuisance RCD trips.

Damaged or crushed wiring — cables pinched under floorboards, screws through conduit, or rodent damage causing insulation breakdown.

Water ingress — outdoor sockets, garden lights, bathroom fittings or condensation entering an IP-rated fitting below the required rating.

Neutral-to-earth faults — a wiring defect where neutral and earth conductors are bridged, causing the RCD to detect a leakage current and disconnect.

Ageing, deteriorated circuits — older rubber or cloth-insulated wiring breaking down with age and causing leakage to earth.

Faulty downlights or transformers — older 12V halogen transformers and LED drivers can develop faults that cause the RCD to trip.

Also: incorrect DIY additions, unsafe modifications, damaged extension leads and overloaded circuits.

How We Fix It

How We Diagnose & Fix an RCD Fault

No guesswork, no unnecessary replacements — just a clear diagnosis and a safe fix. Here's our systematic approach:

Circuit Isolation

We isolate each circuit one by one to pinpoint exactly which circuit is causing the RCD to trip — narrowing the fault to a specific area of the installation.

Appliance Testing

Appliances on the affected circuit are tested individually. Faulty appliances are identified and removed from the equation, confirming whether the issue is equipment or wiring.

Insulation Resistance Testing

Using a calibrated Megger MFT1741, we carry out insulation resistance tests on individual circuits to detect cable breakdown, moisture or wiring defects.

Visual Inspection

Physical inspection of suspect fittings, junction boxes and the consumer unit. Common points include outdoor sockets, bathroom fittings, and consumer unit wiring.

Safe Repair & Certification

Root cause identified, fault repaired safely and tested to BS 7671 standard. No guesswork, no unnecessary circuit replacements. You receive a clear explanation and, where required, certification.
