then i got a riddle to figue out this morning just to make my day a little more interesting...

i was called out to figue out why a circuit breaker trips.

so while driving to the site my head is already puzzling with ideas and the route i will take to solve the mistery...

first thing tong tester on the cable and carry out a load test...

60 amp circuit breaker tripping...full load current 6.8 amps measured in the meter room while everything is running...

ok so this sounds odd

then just to put a spanner in the works...i am told that the circuit breaker doesnt trip durng the day only at night time...when they arrive in the morning the power is off in the meter room...and they switched the main switch in the DB off the ight before...so i look around and find a disconnection notice fitted to a shroud...could it be this?

so i advice the customer to contact durban meter and verify that they havent issued a disconnection notice for what ever reason...unfortunately ther eare no phone lines due to a fire...i woulnder if it was an electrical fire?

if the power is off again tomorrow i will disconnect the supply cable and meger the cable to verify that there is not an insulation fault...which i find hard to believe because if there was it would trip during the day...so no is when i wish i had one of those small cameras to fit in the meter room to see why and when the breaker goes off...i will also fit a recorder to find out what time the circuit breaker goes off.

i see these little camers are becoming affordable...the last time i checked they where only around 5 grand...for a small plastic box which doesnt even look like ther eis a camera in it...everything is built in with a motion sensor to record only when ther eis movement...i thougt of leaving a camera like this on site to keep an eye on my staff but i dont think it would pick them up becaus ethey move so slowly
