This caused some head scratching this afternoon.
Customer said everytime they use the dryer the power trips.
After doing some testing and inspecting on this garage supply, it become obvious there was high resistence on the socket circuit, testing the cables at the fuseboard everything was fine. Insulation resistence also fine.
So I set about running the appliance whilst checking for earth leakage.
When switched on and working. The customer said they heard a crackle and a flash of light come from the fuseboard.
Loosened both MCB either side of the 32a MCB. And out dropped the bus bar without touching the offending breaker.
Replaced and re installed. All is well again!
Just shows when testing to be very methodical and don't overlook potentially the most simplest of things!
