Took delivery of a new dual fuel cooker today. (It's a Cannon Henley dual
fuel cooker not that suppose that makes any difference).
Prior to installation, I had reinstated the old electrical connection (which
had lain disconnected and unused for years when we had a gas only cooker)
and wired it to a new 32amp MCB in the consumer unit. Our unit is split
into non-RCD protected circuits on one side (lights, CH and alarm) and RCD
protected circuits on the other (sockets etc.)
I fitted the new MCB to the non-protected side and everything seemed to work
(at least with a meter)
Fitted the cooker and switched on at the wall and the clock duly lit up and
the igniter worked fine for the gas hobs. Turned on the *gas*
grill and the
power died. The RCD had tripped. Same happens if I turn on the oven.
What's going on? Even if I've fitted the mcb to the wrong side, how can the
RCD trip when the mcb is on the non-protected side?
Any suggestions before I tear the remains of my hair out?
