531.3.1.202

"It is not permissible  to introduce an external connection for the purpose of intentionally creating a residual current to trip an RCD."


What problems, hazard or danger will ignoring this regulation create?

  • I was thinking of using one of Andy's recently recommended under/over voltage monitoring modules configured to be wired in parallel with an R.C.D. test switch. If my whole system was contained in just one enclosure would it comply? Would it be safe?

    It would probably be inconvenient if the power stayed off indefinitely after a disturbance. Hence the suggestion for a contactor - so power could be automatically restored as soon as the supply was suitable again.


    If you really did want it to latch off, an MCB with a shunt trip is probably the more conventional solution.
