Cable clamp look suspicious....
Discuss 3 phase problem after spark did 5 year safety inspection in the UK Electrical Forum area at ElectriciansForums.net
Yep now bear in mind all other tails and switches are pristine is there any votes for system overload the main fuse that blew into the building is also on phase 2Looks like the Red clamp has squashed the cable and split the insulation.
That's allowed the copper core to touch the earthed metal backplate and or the screw holding the clamp.
If it was the cable lose in the terminal or wrong side of termianl clamp it would have fizzled and overheated for a while before ultimately failing.
As Westwood, it looks like a dead short, especially with the ball of copper
It is a dead short. Can you show a more direct pic below the red clamp.
Hi no they can back and replaced the switch and tail and removed the offending bitsIt is a dead short. Can you show a more direct pic below the red clamp.
Seems the wire being nipped seems to be winning the vote can any of you guys see a situation were a nicely balanced 3 phase which was always well well under max amps would see just one phase go up like thisAh so its all sorted....
Yeah but the upshot was that we were running on 2 phases for a a good few hours the fans failed the temp in the building rocketed and a load of other problems as a resultAh so its all sorted....
