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.

    Has anyone tried one of those circuit tracers? The kind that you plug a "transmitter" in on the circuit you want to trace and then wave a "receiver" wand around likely supply point to see which gives the strongest signal? Never had a chance to play with one myself, but in theory sounds ideal for this kind of problem. I'm hoping the cables between the meter and switchfuses are insulated & sheathed so shouldn't screen out the trace signal (unlike perhaps the SWA armour).
