Safe Disconnection to Undertake Work.

Zoomup
Scene. An old farm building now used as a double glazing frame maker's workshop.


The supply comes from an old shed about 40 metres away, where the meter is. The old shed has some 70s/80s rusty M.E.M. isolators that feed several S.W.A. cables that exist the shed in many directions underground. I suspect that one feeds the main farmhouse, another a rented cottage and the others various farm buildings. There is no clear labelling of the isolators.


What is the best way to locate the frame maker's  building supply where I have to work?


Somewhere I have a circuit i/d set, if I can find it, but that will need access to the live parts and I do not wish to turn off the wrong isolator.

    My preferred solution would be to use a load of significant size, say 3kW or more & have a assistant turn this ON & OFF on command by using radios or mobile phones. It should then be easy enough to find this current at the supply end.


    I hear what you are saying about the cables being in trunking but it must be possible to remove the trunking lid?


    I can't see anyway of doing this without some (temporary) modification to the existing system


    You could always add a 13A socket short term/
