RCD keeps tripping — Swansea diagnostic visit

Access, timing and tenants are all workable — say what you need when you book. You are welcome to watch the tests being taken and ask what each one means.

A short guide to rcd keeps tripping for Swansea property, written by the person who would do the work. We attend homes and businesses across SA1–SA7 weekly for exactly this fault. People often expect the worst outcome. In practice, most Swansea visits of this kind end with a defined, limited piece of work. That detail is what a proper survey is for.

We attend Swansea calls from a base that reaches the A483 and Fabian Way within minutes. The practical question on this job is RCD keeps tripping, and it is answered by testing rather than by opinion. In Swansea that usually decides both the scope and the sequence of the visit. That is one reason our price does not move after the survey. Owners and landlords across SA1–SA7 ask about this in roughly equal numbers, for slightly different reasons.

Likely causes

Cumulative earth leakage from multiple circuits sharing one 30mA RCD — each circuit is fine alone but together they exceed the threshold.
A faulty heating element (immersion, shower, oven, dishwasher) leaking to earth.
Moisture in an outdoor socket, security light or garden circuit.
A failed neutral-to-earth connection inside an appliance.

Safe checks you can do first

Turn every MCB under the RCD off, reset the RCD, then bring circuits back one at a time to find the offending one.
On the offending circuit, unplug appliances one at a time.
Note whether it trips more often in wet weather — a strong clue for outdoor water ingress.

When to stop and call

If you can't isolate a single circuit or appliance and the RCD trips within seconds of reset, call — it's a wiring fault, not an appliance.

How we fix it

We insulation-test to identify the leaking circuit, then trace to accessory or appliance. Where the board is a shared-RCD split-load design at end-of-life, we quote an RCBO upgrade so each circuit has its own dedicated protection.

Typical price: £95–£180 diagnosis + repair. RCBO board upgrade £550–£950 depending on circuit count.

FAQs — rcd keeps tripping in Swansea

Should I upgrade to RCBOs?+

If nuisance tripping is chronic and the board is 10+ years old, yes — RCBOs give per-circuit protection and eliminate the shared-threshold problem.

How long until you can attend?+

Same-day for genuine no-power situations; next-day for intermittent trips you can work around.
