What is the recommended insulation test on a hard wired cooker?
How can the test be carried out on a built oven without removing it from the housing?
How do you protect the PCB’s and electronic timers?
I’ve read a lot about this subject on the forum but can I please have some straight forward advice and wisdom from those of you who are more technically able so that I can be sure I’m doing the right thing.
Re: How to do an insulation test on a built in cooker.
If you don’t want to remove it from its housing, remove the circuit breaker or fuse in the consumer unit, switch it off at the wall switch and test it from there. I’d say 1Megohm would be the minimum value you’d be looking for.
The electronics should withstand a 500V test, probably also 1000V.

That’s a very neat way around the problem thanks.
I’ve been doing this job for 26yrs but I’m not a qualified electrician nor do I have part P. So would there be any problem with me testing from the consumer unit from a legal point of view.Re: How to do an insulation test on a built in cooker.
Another thought if I test from the consumer unit in that way, because I haven’t connected the Live and Neutral together for the purposes of the test then wouldn’t some current pass through the “delicate” electronics circuits.
I was always taught to disconnect all electronics before going near anything with a meggar. But of course that can’t be practically done any more.Re: How to do an insulation test on a built in cooker.
Read roly’s reply properly – u don’t test from consumer unit – you test from cooker unit or isolator – unless u disconnected wires at consumer unit before testing u would be testing all circuits on board

Very sorry Roly I should have read it properly as franz said 😳
Your neat solution makes makes even more sense now, thanks.Re: How to do an insulation test on a built in cooker.
But my point about me being able to test from the cooker point ie the house wiring still stands.
If I remove the cover from a cooker point and test the built in cooker from there how do I stand legally if I’m not a qualified electrician or part P registered? 😕Re: How to do an insulation test on a built in cooker.
would’nt it just be easier to remove oven from housing?
FranzRe: How to do an insulation test on a built in cooker.
Easier said than done when it’s a big double oven in a high housing and your on your own.

we can replace a socket outlet or cooker switch, but we can’t move it.Re: How to do an insulation test on a built in cooker.

Sorry, I had to go off-line.
Thank you for your time, I couldn’t have wished for a more thorough answer. 😀Re: How to do an insulation test on a built in cooker.
That’s ok. that’s what this forum is for.

Re: How to do an insulation test on a built in cooker.
Any electronics, take the cable to oven out at isolator or fusebox (once you have actualy removed all 3 cables) and join L/N together and test to earth, anything over 1 meg ok. I always short L/N in a connector to make sure because if 1 of them slips out duing test you could frazel the pcb ete.
This is always done now on all appliances and circuits I rairly test L/E N/E anymore its to risky. ( central heating, flu lamps, xbox, plasma’s are the worst. )
