Question on carrying out Zs testing. Please Help.

[nazoom]

When carrying out Zs test for a particular circuit lets say Socket, what happens to the RCD protecing that circuit does it have to be ON or OFF? I know that the socket under test must be On and I know it is a live test.

Many Thanks.

You've answered your own question, it's a live test

So the RCD must be On!! Is it possible that the RCD might trip when doing the Zs test? It is a domestic installation?

Thanks

Heavens! This is a bit fundamental mate, it's a live test, so you must have a supply available at the socket therefore if the final circuit is RCD protected the RCD must be latched in the ON condition. Normally in order to do a Zs test the meter will need to be set on a No-trip range to prevent the RCD tripping under test.

Thanks for clearing that.

I suspect he's working with unsuspecting customers!

I think I'd rather he was asking 'stupid questions', rather than not bothering to ask due to being embarressed because of people making sarky comments.

Just to get you guys to understand I am still training and haven't yet passed my exams.

Thanks anyway.
