Swansea: how we fix fuse box keeps tripping

The point of a proper test is that the result is repeatable by anyone else with the same instrument. In practice that means checking fuse box keeps tripping before anything is replaced.

Before booking anything for fuse box keeps tripping, it is worth knowing which findings change the price and which do not. We serve Swansea and the surrounding SA1–SA7 area with same-day or next-day diagnostic visits and a fixed-price fix at the end of it. A written record matters as much as the work. Anything we find at a SA1–SA7 address is documented in a form you can hand to someone else. If it turns out not to apply here, you will be told that plainly.

Book same-day or next-day — don't keep resetting. Anything we recommend is tied to a specific finding rather than to a general principle. Around Swansea Council that is a familiar finding rather than an alarming one. Swansea enquiries about fuse box keeps tripping tend to arrive with a deadline attached — a tenancy, a sale or a fault.

Likely causes

A faulty appliance dumping current to earth — kettles, washing machines and immersion heaters are the usual suspects.
A shared RCD tripping because two circuits together exceed the 30mA leakage threshold, even when each is fine on its own.
Water ingress into an outside socket, garden light or shed circuit after heavy rain.
A worn RCD at end-of-life — 15+ year-old devices lose sensitivity and false-trip.

How we fix it

We insulation-resistance test each circuit under the RCD, isolate the faulty one, then trace the fault to the exact accessory or cable. Most faults are found and made safe on the first visit; a full RCBO board upgrade is quoted only if the whole board is at end-of-life.

Typical price: £95–£180 for diagnosis + first-visit fix on a single fault. Board upgrades quoted separately if needed.

When to stop and call

If the RCD won't reset with everything unplugged, or you smell burning, isolate the main switch and call.

Safe checks you can do first

Unplug everything on the tripping circuit, reset, then plug items back in one at a time.
Check whether the trip happens at the same time each day (immersion timer, storage heater).
Look for scorch marks, warmth or a burnt smell around sockets before touching anything.

FAQs — fuse box keeps tripping in Swansea

Is a tripping RCD dangerous?+

The trip itself is the safety device doing its job. What's dangerous is repeatedly resetting a trip without finding the cause — that's how socket fires start.

How long does diagnosis take?+

Most single-fault diagnoses are done inside an hour. Intermittent faults that only appear at certain times can take a return visit.

Can I keep resetting it until you arrive?+

No. If it won't hold, leave it off and turn on the circuits you actually need one at a time. Don't force the RCD closed.

Swansea context

Age alone does not condemn an installation. Plenty of older Swansea wiring tests perfectly well; some newer work does not. It gets photographed if it will be hidden afterwards.
