this is a second hand job, basically a friend who is a spark has asked me for some advise and i couldn't help and thought someone here might.
two portacabins side by side,
both have
1, 2way c/u with rcd main switch, 20a mcb for two sockets, 6a mcb for 2 external bulkhead lamps and 2 5' flo lights
the second cabin is fed from the supply of the first via a swa laid underground, length @ 4m
both are supplied from a generator, type/kind, i have no idea
problem is that every morning when the genny is fired up the lighting in portacabin 2 will not work even if the swithes are in the on position until both mcbs and rcd are turned off then back on again at the c/u
switching the light switch has no effect either
turning just the lighting breaker/just the socket breaker or just the rcd alone dosent work, it has to be all 3, my mate has tried and confirmed this,
there is nothing plugged in the sockets in either cabin but the outlets are powered up on starting the genny
lighting in cabin 1 works perfectly
my mate is almost retired and hasn't done any testing other than flicking the switches and plugging socket tester in sockets.. :|
i have no other info to go on at the moment
can anyone shed any light lol :coat or offer an explanation,
its about 80miles to the site and although i've been asked to go at the weekend i would rather go thinking i could sort it.
thanks
