How a simple job can go wrong quickly....

Not my work before I relate:


Existing 3-ph circuit breaker DB in a shop has a 30 mA 4 pole RCD belatedly fitted in a separate enclosure to provide blanket RCD protection. OK, not ideal.

Electrician asked to install extra 13 A socket-outlet in window during shop hours so padlocks off the circuit's circuit-breaker and proceeds, He lets the circuit neutral and cpc touch when fitting the socket-outlet and out trips the RCD as expected. Resets and shop keeper then announces that the card reader, till, air-con and some lights not working.


All that equipment now duff (technical term!).


For an interesting weekend quiz, what happened?


Without hindsight and the work being done during opening hours, what would you have done differently?

    Where would you detach the neutral the neutral?


    In the distribution board whilst all the other circuits are live?


    Are you sure you have the right one?


    I presume the equipment was damaged due to their circuits going up to 415 volts, but I’m still trying to figure out why.


    And I’m sure we have all tripped an RCD working on a circuit that has had the live isolated.
