I remember seeing something similar when i was a lad,there were these blokes from manweb isolating a side street where all the houses were being knocked down and they opened up a junction box in the pavement attached 2 heavy leads with a big knife switch on one end and ran it about 10 feet from the box,one of them closed the switch by kicking it and there was a big flash and a bang quite fascinating when you are a kid.Anyway I went and asked what they were doing and apparently they couldn,t locate the fuses for that circuit so the easiest way out was to blow them.must admit I,ve been tempted myself on some old factory boards lol.
