At least they have the machinery to handle it.

Those large sized SWAs are an absolute pig to manoeuvre.
I like it! Ratchet straps and a lump hammer to install them
Took a bit of manoeuvring!

@RF Lighting It looks like the bend into the bottom of the board was probably the hardest bit, looks rather tight, but whats going on with the SYs...... (I don't like SY!)
@SUNRAY I'm reminded of an issue with some lights in a cabin tea room once, tripping out (I think the RCD and teh MCB as well sometimes - it was a while ago).Switch start fittings, circuit tested out ok on IR even on 1000v seemed to be one fitting in a small officey area at the end that was doing it as it was switched, but not every time. Stopped when the L and N were disconnected in the fitting. Ended up putting a new choke in it and the problem went away, old choke still tested allright on IR at 1000v, think I put it downto something like when starting the EMF in series with the mains was much in excess of what I could test at and allowed something to flash over, or the physical forces when starting closed up a fault that was not there when the windings were allowed to 'relax'

Careful with those asbestos flash pads!
Bagged up immediately after pic taken.

Can you see any obvious damage to the cable, or is it an internal breakdown?
The 2 pieces shown are only about 4-5 ft long from inside the buildings and test fine, almost as soon as the cable was powered down the 100 plus metres was being chopped into handleable sized lengths and chucked into a dumper truck so we never stood a chance to look at it.
BTW that CI box is identical to the one with problems, the other is not pristine white flashgaurds, infact it's very horrible black and green.
