Delayed tripping on RCD Discussion ThreadDelayed tripping on RCD Electrical Advice
Not even sure where to start with this…
Got a split board RCD which is tripping after 10mins of being ON. Never had this before. I thought I identified the circuit with the fault (RCD trips immediately when circuit on) but looks like a fault on more than 1 circuit
Customer just had a brand new rewire, I don’t think I have seen it this bad before on a brand new rewire
I’m back there tomorrow to do more testing. My question is aside from everything wrong with the install, is there a scenario where a RCD will trip after 10mins of being ON without a light / socket / appliance switched on and off?
