tests

[blueboy]

hello,
i don't suppose anyone knows why the electrical tests are done in a certain sequence do you?
thanks in advance

I'm sure a lot of people do Is this a study question or is there another reason you want to know this.

Welcome.

To get the best out of the forum its a good idea to offer up your thoughts so people can understand where you are coming from.

as you're new, i'll allow a bit of latitude. obviously dead tests before energising. then break that down a bit further. you don't IR test a circuit until you've determined that the circuit is complete. i.e. continuous. so continuity, the IR, then you know it's safe to powere up. then live tests, Zs, then test |RCD.

Coz the book (bs 7671) says I have too!

There is indeed a reason, a very important reason.

What you reckon ? Give it a shot.

Does each one rely on the next?

Think about the sequence of tests and if they need to be energized and if you could do them if energized or not??? eg, r1+r2??? What would happen if you linked out Live and CPC then turn it on???

Ahh yeah, it would trip!
