Fault finding and tripping RCDs

A board that trips, a dead circuit, a socket that smells — diagnosed and fixed, with the cause written down.

The RCD in a Maltese board trips at 30 mA of earth leakage, and it does not say where from. In practice the usual suspects are an ageing water-heater element, a damp outdoor socket after rain, an appliance with a leaking filter, humidity in an unused room, and — increasingly — inverter air-conditioning or appliances sitting on an older Type AC RCD that cannot read DC-offset leakage. Fault finding is a process of elimination with a test meter, not a guess with a screwdriver.

We publish the call-out and fault-finding bands so you know what a visit costs before you ring. If the fix is a Type A RCD or a new element, that is priced on the spot.

What this covers

What it costs

Maltese guides put fault finding at €60 to €150 and emergency work at €50 to €100 an hour. The call-out band covers the visit; labour on the fix is on top and agreed before it is done.

A band, not a quote: the low end is a straightforward job with clear access, the high end is the same job with the complications a site visit finds. Materials are included where the line says so.

How it works

You deal with us, not with the trade. We visit, we quote a fixed price, we bring in a REWS-authorised electrician from the CheckYourTraders-verified network, and we stand behind the work. One point of contact, one contract, one invoice — and a certificate at the end.

Questions people ask

Can I just replace the RCD with a bigger one?
No. The 30 mA figure is the regulation, and it is there because that is the level at which a shock stops being survivable. The answer is to find the leak, or to fit an RCD of the right type if inverter loads are the cause.
Is a tripping board dangerous?
The trip is the safety device working. What it is protecting you from — a wet socket, a failing element, a damaged cable — is what needs finding.
