WHAT WOULD YOU DO?

John Peckham
Today's job inspect and test a domestic installation in a sheltered housing flat. TN-C-S earthing system. Main protective bonding correct. 


Wet room for disabled occupant. Electric shower and extract fan supplied from a Wylex 2 way consumer unit  with BS EN 61008 30mA RCD main switch. Recently installed.


RCD does not trip on X1 RCD test but does trip on X 5 and operation of test button. RCD does not tip on a second and third test after X 5 test and operation of the test button.


Thinking about the Note to Regulation 643.8 are you content with this installation as there are no other observations recorded and prepared to issue a "Satisfactory" EICR?

    Interestingly in B.S. 7671 16th Edition of 2001 in 713-13-01 it just says: "Where protection against indirect contact or supplementary protection against direct contact is to be provided by a residual current device, its effectiveness shall be verified by a test simulating an appropriate fault condition independent of any test facility incorporated in the device". No figures specified.


    Although 412-06-02 specifies an R.C.D. of 30mA to operate at 5X its rating within 40 ms as provided for by BS 4293, BS 7071 BS 7288, BS EN 61008-1 or BS EN 61009-1
