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?

    What weighs the scales in this situation is
      .....a sheltered housing flat.


    Wet room for disabled occupant.

     



    If this was a bog standard wet room [ no disabled type hand rails and extra supports etc ] in a single household, the risk may not be so great and not so likely to be danger. A C3 could be issued with a bit more confidence.


    I personally do not think it hinges on 5 x  being okay. I know the regs use "rated", but surely the x 1 test is there to prove the rating of the device for purposes of 415.1.1.


    It could, after all , be a 100mA RCD in disguise?Airplane


    Also, this is "recently installed". So a decision was made to provide a 30mA RCD . There should not be the need for improvement. You have to default to there being a failure in the device operating at its rated operating current.
