RCD Testing - The RCD only or from the furthest point in the circuit?

Closing this down because the answers are increasingly off topic and missing the point.

  • Our sheets actually direct us to simple test the RCD at the RCD.

    Depending on how that test is carried out, it can be dangerous without carrying out other tests first.

    If you are testing by returning the fault current down a protective conductor, and that protective conductor has not been verified first, hazardous touch-voltages and touch-currents can be imposed on parts of the installations for a period of time.

    This is covered in IET Guidance Note 3.

    wo ways of looking at this:

    (1) Do as you are told; or more formally, do what it says in the contract. I am not sure what "simple test" means - is that just pressing the test button?

    Doing 'as you are told' when it's not safe is a potential breach of legislation.

    Doesn't 643.8 cover the R.C.D. testing situation?

    It doesn't tell you exactly how to do the test (and when it may not be safe to do the test) ... as the person carrying out the test is supposed to be competent.

    Yes, but your employer will be vicariously liable.

  • "Depending on how that test is carried out, it can be dangerous without carrying out other tests first."

    My R.C.D. tester has lights that show a go or no go safety situation. It would tell me if the C.P.C. was not present.

    But that doesn't remove all liability (criminal and personal injury, at least contributing to one's own personal injury) from the employee.

    This is because knowing something is dangerous and doing nothing about it is a breach of legislation (Section 7 of the HS@W etc Act). There is also such a thing as contributory negligence on the civil (claims) side.
