Top flat, all power gone

[Softus]

Maybe could find it by thermal imaging after it's been sparking fora while...

The route for a replacement would seem to be up the outside wall, some 10 - 12m height.
Am I right in guessing that that would
1) be something like 16mm² SWA?
2) need scaffolding to be fixed - or would a ladder be reasonable.?

16mm² SWA should be good for 80A, if that's what you need. Someone told me yesterday that anything above three steps on a ladder, outside, contravenes the "working at height" regulations. I haven't looked them up yet though.

As ricicle said, it's an interesting one - can't wait to hear the outcome. If I could be of any qualified help I'd happily offer, but I've no more status or knowledge than you do on this one.
