Why does my RCD keep tripping in Ebbw Vale?
RCD keeps tripping in Ebbw Vale? Common causes, what you can check safely and same-day diagnosis from a NICEIC engineer.
What matters for fault diagnostics is the condition of this installation, not the average condition of installations generally. The point of a proper test is that the result is repeatable by anyone else with the same instrument. It gets photographed if it will be hidden afterwards. fault diagnostics tends to be judged on the finish, but the part that matters sits behind the wall and only shows up in the readings. In practice that means checking faulty appliance (most common cause) before anything is replaced. Whether this is urgent or simply overdue, the sequence for fault diagnostics does not change much.
- Failed RCD itself (rare but happens) We flag it rather than assume you know.
- Practically speaking — same-day diagnosis if you can't isolate it
- If the trip is on a shower or outdoor is the finding we would check first on a Ebbw Vale property.
- Damp ingress and age combine, and faulty appliance (most common cause) is the outcome.
- Damp in outdoor/bathroom circuits — the point at which a small job can turn into a larger one.
What's different about Ebbw Vale
Unplug everything on the tripping circuit, reset the RCD, then plug each appliance back in one at a time. 9 times out of 10 in Ebbw Vale homes, one appliance is the cause. We flag it rather than assume you know.
Practically speaking — many Ebbw Vale homes still have the original wooden-backed wylex fuse boards from the 1970s that no longer satisfy any landlord EICR — older RCDs lose sensitivity over time and trip on tiny earth leakage that a new device would tolerate.
Not glamorous, but common: cable damage behind plaster.
Failed RCD itself (rare but happens). We check it early because it is quick to eliminate.
How we'd do it
- 1IsolatePart of the visit: most faults repaired on the visit.
- 2FixPractically speaking — most faults repaired on the visit.
- 3CallOnce access is agreed we if you can't isolate it, phone for diagnosis.
- 4TestInsulation resistance test pinpoints the circuit. Checked at first fix and again at test.
Common questions
What if the property has had DIY work done?
It gets tested like anything else. Cable damage behind plaster is often the result of well-meant work that was never verified.
Do you charge to come out and look?
Attendance and testing are quoted before we travel to Ebbw Vale, so there is nothing added afterwards that was not agreed.
Do you deal with the paperwork for the council?
Where notification is required, it is submitted to Blaenau Gwent County Borough Council as part of the job.
Do you offer scheduled repeat visits?
Yes. Where an installation needs periodic checks we diary it rather than leaving you to remember.
Do you cover Ebbw Vale for fault diagnostics?
Yes — Ebbw Vale and the surrounding NP23 postcodes are part of our regular working area, including Tredegar and Abertillery, and Blaenau Gwent County Borough Council notification is handled by us where the work requires it. Nothing here is optional.
Do you work on commercial premises too?
Yes, across NP23 and the wider area. The testing regime differs but the approach is the same.
Bookings are made around access — tenants, trading hours or a school run all work. We cover Ebbw Vale and the NP23 postcodes, including Abertillery, for fault diagnostics. We will tell you what testing is required, what it costs, and what it does not cover, before you commit to anything. We cover Ebbw Vale and the NP23 postcodes, including Brynmawr, for fault diagnostics.
