disconnecting and reconnecting an electric cooker?

martin57

Hi,

I am putting in a new electric cooker which has the same wiring as old one. The old hotpoint cooker has 3 wires a brown neutral and brass wire (which I take is the earth) and the newer cooker is the same setup. The old cooker has a box in wall with a red light on it, which lights when cooker is on and it is wired with the 3 wires above to another wall plug. (has a cover held on with 2 screws)

Do you think it is straight foward enough to undo the 3 existing cooker wires in wall and then just hook up the new cooker?

What worries me is that my sister in law says that even though cooker wall switch is off and the mains fuse box is also switched off, that an electric cooker has still got a live wire with a live current?

thanks for any advice offered,

if the cooker box has a neon on it, go to the fuse box and pull out the fuse that turns off the neon. The cooker box will then be isolated. Play safe though, if in doubt get an electrician out!!

Hi again,

Thanks for reply. I got a new main fuse box in house last year, the kind that doesn't s have any fuses, works by trip switch. SO I would switch to the off position the main on/off switch there.

Probably what I want to know as regards the cooker is, if I switch off the main supply box in house will the cooker be without a electric supply too i.e safe to work with.. (as someone else has told me that it still have a live wire even though main fuse box in house is off) I notice that it has its own cooker trip switch in there.

Assuming that the wiring has been carried out properly, switching off the cooker supply at your Consumer Unit will isolate the cooker circuit. Switching off the mains supply fully does just that - switches everything off. If you're still unsure, expose the cooker wiring and test for supply after you have switched it off at the consumer unit. There should be none. If in doubt - leave it to someone else.

Switch off at the main fuse box when the old cooker is still in, if it doesn't work when the mains are off (and it shouldn't unless it is very very badly wired :eek:) then you should be OK. You should still test with a multi meter (maplin do real cheap ones) just to be sure. Then simply switch the cookers over and wire up, make sure you sheath the earth (the bare copper wire you mentioned) and then switch back on at the mains.
