certification question...

[matt.leung]

just been thinking....

could a partiall re-wire be on a minor works, if there is no consumer unit change, as the cleint has had a new board put in, and all of the existing cables have gone into JB's than JB's into the new CU..

the clients just wants new cabelling for the upstairs lights and sockets, as at the moment it is the old rubber type of cables, and the insulation is old and falling apart. So really it is just a large alteration, that has not extended to the provision of a new circuit.

The electric shower circuit is to remain as is. and the bathroom light and WC light is operated via pull switches, so all the cabelling is done in the loft apart to the couple of connections...

Your thoughts and advice are welcomed...

many thanks

If you are changing the type of cables then you should be doing a EIC.

Concur.

You ARE providing a new cct, IMO, as you`re removing the old circuit, and putting in a new one. EIC all the way.

id go with EIC

 

[Evans Electric]

Yes EIC . If you look it up a MWC is what it says , really minor stuff.

a plumber told me about a builder that was 'rewiring' a house. when he asked the builder why he was jb on to the old cables the builder said that because he isnt allowed to install new circuits. Defined scope part p at its best.

the spark was part p reg, as i saw the test results.

what surprised me was, that he has installed a new CU, and only carried out tests on the two new circuits that he has installed... No PIR done at all.

 

[ianmacd]

He didn't even perform basic testing of the old circuits?

why do a pir you are not required to do one, I would only test what I had done and note that on the cert. if I had noticed something wrong I would not this in the section about comments on the installation

If you don't test the existing circuits, how can you be sure they will trip an MCB within the required times?

You should read BPG #6

if you change a CU you have altered every circuit therefore you are required to test every circuit you have altered.
