Testing Zs on lighting circuit.

[graeme210375]

Hi all

I know this debate has been bounded about the forums in past with various responses.

Usually I measure Zs from the furthest pendant.

However if I use this method during my Elecsa assessment next week, will I be pulled up on unsafe live working practices?

My argument is that within the ceiling rose, the conductors are insulated and terminated within insulated connectors, so, with GS38 probes, presents very little risk of shock

I know the adding up method is acceptable, but don't feel its best practice unless its impractical or unsafe to measure directly.

The assessor decides what test you do they usually get you to Zs a socket outlet dont panic

Kewtec adapters?

You still need to remove the cover to get an earth connection

Kewtec adapters?

Could be an option, just holding off on spending more money till after Xmas.

In the last 6 years ive not been asked to test a lighting circuit once on inspection

The kewtec adaptors are good though

How do they expect you to take Ze then?!

I think I'd end up having an argument with them on this subject!

Live testing is a whole different game from "manipulation of live conductors". The latter will get you in trouble, unless you have all the PPE, sufficient knowledge and experience, and a cast iron excuse for HSE as to why you couldn't work dead.

+1 on the Kewtech adaptors - brilliant for the B&Poo lights that people want fitting for next to nothing. You know who you are...

"How much? That's more than the light cost."
"Indeed it is , but I don't live in China. You could get a Chinese electrician, but I suspect the travelling costs would push the price up"
"Mmmmm. I'll think about it and let you know"

Exactly!
Live testing isn't 'Live working' in my book.

How on earth could you be an electrician if you can't test live circuits?!

When you do buy them shop around for the set rather than buying individual ones as the set is cheaper in the long term. A word of warning, they can give odd readings

Cheers for the heads up. EBay has set of 5 for £48 free delivery. Money bit tight at the moment.
