10 second trip

[Marvo]

It's not a shared n. Been working for the past year they said. IR test 0mohms between L and N.

Could damp cause it to trip after 10 secs? Why dies it happen after that long. Surly with a short it would trip straight away?

A low IR test with a megger tester doesn't indicate a 'short' it indicates an insulation or earth leakage fault. Just incidentally if it's an RCD tripping fault why are you testing between the L+N instead of linking the L+N together and testing to earth?

If we can get down to the nitty gritty of what tests you have conducted and how....it may shed some light (good pun) on whats causing the fault

0m ohm is a dead short.

IR test 0mohms between L and N.

0m ohm is a dead short.

Is it 0 ohms or 0mohms (milli ohms) is it 0Mohms (Mega ohms) whilst testing with a megger tester? You're confusing the kak out of me.

Jiga, for hell's sake there's a procedure for fault finding. It's fairly basic stuff.
Put together a list of what tests you have carried out and how you have broken the circuit down and then maybe we can help you out.

Every day archy ! ! Oh you meant me !
I didnt do it on bloody purpose . It fookin hurt .I'm gonna take me Zimmer frame to work now

You could always get a nice blond wig and go on of those womens chat shows.

0m ohm is a dead short.

If you mean 0.0 MΩ then this could be any value of resistance up to 99,999Ω, or 49,999Ω if the meter rounds up.
Hardly a dead short.

Admittedly 0.0 milliohms (0 mΩ) is a dead short

Don't need a blonde wig I'm an essex geeze mate

0m ohm is a dead short.

If you can't understand the readings your instrument are giving, have you ever considered you're in the wrong game?
This is schoolboy stuff!!!

It appears the op has been frightened off..

he sounds like a muppet.

what kind of a tool would bother just doing an r1 test.

take the lamp out and do an ir/r1

a good chance you will read through most lamps

Just another electrical trainee that hasn't got a Scobby Doo, of what the hell he's doing!!

i made a feeble attempt in post#4.

I love it when Trev starts to get mad. All northerners have this perfect zone where sarcasm and honesty are perfectly merged.

I do think the OP gave up though

that's the thing with us northerners,we're plain speaking,if you don't like it you shouldn't have joined as my old mum used to say.Or in this case the op should have explained himself properly,honestly the way some people are so cryptic you'd think they worked for mi5.

I think, and its only a opinion mind you, that if you read through the posts like a script its like Hancocks Half Hour, Sorry if its before your time but most will get it,
