My RCD has tripped and won’t reset, what shall I do?

When an RCD (Residual Current Device) has tripped generally more than one circuit would have stopped working as the RCD would operate to give additional protection to more than one breaker/circuit but how can we establish which is the faulty circuit?

Green Electrical would recommend that all the breakers on the RCD side that has tripped are switched off. The next step would be to reset the RCD which should hopefully hold. If so, individually switch on each breaker, if the fault is still an issue then the RCD will trip on the circuit that is switched back on. If that’s the case, repeat the process as above, leaving the faulty circuit/breaker off and call a us for an NICEIC electrician to Fault Find and repair or feel free to contact Green Electrical for further advice on 0800 051 9324.

If the RCD doesn’t re-set by following the steps above, then it is most likely a natural to earth fault and a professional fault finding service is required.
