Hi, i went to a call out a couple of weeks ago to a kabab shop. Its single phase supply. i went there and they had blown the main fuse 80amp. Iv checked all the circuits at the consumer unit with a quick ir test no problems i know this would be no problems as nothing has tripped. So i got western power to come out and put a new fuse in. I then put a clamp meter on the mains which then read 87amps.So i told them they need to have the service head upgraded to accomidate 100amp fuse or use less equipment. They agreed that they would use less equipment and save costs.
I then get a phone call last nite saying that the electrics have gone off for a bit then come back on again but nothing at the board has tripped (RCD protected). Would the main fuse over heat the contacts and go off for abit due to the load and come back on but not blow?
