A fuse box that keeps tripping is doing its job: something on that circuit isn't right, and the RCD or breaker is cutting the power before it turns dangerous. The usual culprits are a faulty appliance (kettles, washing machines and cheap chargers are regulars), moisture getting into an outside socket or light, a damaged cable, or a circuit that's simply asked to carry too much. The quickest home test is to unplug everything on the affected circuit and reset it: if it holds, plug things back in one at a time and the faulty item usually gives itself away.
If it trips with nothing plugged in, trips the instant you reset it, or you can smell burning or see scorching around a socket, stop resetting it and get it looked at. I trace faults across Caerphilly and the valleys every week, from the older wiring in the Victorian terraces near the castle to the newer estates around Energlyn and Penyrheol, using calibrated test gear rather than guesswork. Being NAPIT registered I test properly, fix what I find and certify the work, with one fixed written price agreed before I start.
Found, not guessed
Calibrated test gear traces the actual fault, so you're not paying to swap parts on a hunch until something works.
Honest advice first
If it's a failing appliance rather than your wiring, I'll tell you, and you've lost nothing but a phone call.
Fixed and certified
Whatever I repair is tested and certified afterwards, so the fix is proven safe rather than just holding for now.
Your questions, answered
Is a tripping fuse box dangerous?
The trip itself is the safety system working. What's dangerous is ignoring a repeated trip or holding the switch on, because that's a live fault being fed. If a circuit won't stay on once you've unplugged everything, have it traced properly.
Why does it only trip when it's wet?
That pattern usually points at an outside socket, light or cable letting water in. Rain gets into the fitting, the RCD sees the leakage and cuts off. I find the affected fitting, dry it out or replace it, and reseal the run properly.
It trips at random with nothing obvious on. What now?
Intermittent trips are the ones that genuinely need test equipment: a failing appliance, a nicked cable under a floor or a tired RCD can all look identical from the outside. I test circuit by circuit until the cause is pinned down, then agree the fix before doing it.
