Hello All,
I've been call to a small chapel as the power goes on and off once or twice a week.
Cable is a 50mm 4C fed from a 100A 6kA MCCB 50-60m away. 4pole RCD in Chapel.
Load on each phase is about 20-35A when the A/C kicks in so MCCB and cable OK for that.
IR at 500V Fluke 1653B. Results...

RCD tripped. so I isolated each circuit (only 4 and...
What reasons can anyone think of why a circuit would have a dead short across all 3 conductors ?
so far I'm thinking
- water damage
- possible rodent / pest damage
any more ?

Interested to hear people's thoughts on best practice for proving dead and achieving safe isolation on an Economy 7 board - the problem being, (unless you work 0000-0700 GMT :wink5:) the Economy 7 supply is unenergised. So 'proving' your means of isolation achieves dead actually proves nothing...
