Hi, what is the current requirement for RCD additional protection on a socket circuit? Is it for just the socket outlets or for the whole circuit?
I have builders in, who keep tripping the RCD with their mixer, pump, breaker etc. I have given them a dedicated circuit on it's own RCBO which at least means they are not taking out other parts of the house. However the RCBO keeps tripping - I've ramp tested it to 22mA and there's <2mA of natural leakage. I'm on TN-S with Zs 1.6.
Would it be acceptable to move the circuit back to a non-RCD protected MCB and change the socket to an RCD socket? At least that way they could re-set it themselves without having to come into the house. That would protect the equipment but not the circuit.
Or would it be OK to log a deviation to temporarily (months) provide a non-RCD protected circuit only for construction use? Do construction temp supplies use RCDs?
Cheers
