Brain Fried - Help

[SKY]

Firstly thanks to all for the help and advice recently.


I'm struggling slightly to know exactly what cert I need for a CU change for my Part P assessment.
I'm fine with all the testing and the results but just unsure to what extent I need to test and inspect on a CU change.

I have done all R1 R2 test plus ins res on all circuits but somehow feel that this maybe to much when doing a CU change in the real world.

I'm doing a full Domestic EIC with schedule of inspection and full scheme of tests.
Is this overboard?

On an RCD test (Dual RCD board) do I need to test every circuit or just the 1 circuit per RCD side of the board and replicate the reading for the circuits on that side?

On the RCD test, you're testing the RCD, not the circuit, so test each RCD once, ideally at the RCD itself!

 

[kingeri]

I would just put the reading in once and 'ditto' it. You would fill all boxes in if testing RCBOs.

Its not overboard Sky, you'e done everything correct on the cert side of things, look at appendix 6 if you need to refresh your brain (like we all need to do from time to time).

Another question:

On the Schedule of test results it asks for reference method - as I have only done a CU change I do not know the reference method, what do I put in the box?

Cheers

Fill it in as best you can - surely you have an idea of the ref. methods?

In domestic its normalaly method c but could be in metal conduit so open up a few switches and socket and have a look

Could be trunking, insulation etc. too. In old days, pretty much clipped direct or in conduit, but need to be a bit more specific these days!

Really? I would re check that. A, B, 101, 102 etc..
