    What's common practice with IR tests on lighting circuits?

    I had just installed a heat alarm on the downstairs lighting circuit during a kitchen rewire.

All of which say do...

    Sequence of tests in guidance note 3 (initial verification)

    How come the sequence of tests in guidance note 3 is that the Zs test comes before the PFC test? Isn't it normal to do PFC test before the Zs test? Because then you can do your PFC test, put the board cover on and energize the board without coming back to do the PFC test.

    RCBO tests

    Anyone an idea why an RCBO measures >40ms on a 5x test on the second half of the sine wave but all other tests are within requirements?
