Certifying remedial including dist board swap.

[Inteificio]

Hi,

An easy question if you know the answer.

My house recently failed an eicr done by me.

I've had a couple of jobs I'm fixing (split ring separating into 2 circuits), and some I'm not (no cpc on plastic light switches Upstairs, presumably compliant at time of install. The lights have a cpc as a later addition).

I'm swapping the distboard to full rcbo/metal to give me the room to split the ring to two circuits.

So for the schedule of tests....what needs doing?

Just certify the board/supply?

The above + circuits repaired?

Every connected circuit?

Every connected circuit and two sub dbs with their circuits?

This is going to be notified directly so want to know what should completed?

I'm testing everything, but if I'm completing the full form, then what do I do about the C3?

If you are changing the split ring into two radials have you identified the split leg between power points and isolated / disconnected it?

Yes.
Wire under the floor disconnected at both ends.
Two separate radials, hence wanting to split the circuits.

So what's the C3 I'm not sure what you are asking?

I'd C2 a split ring.

The C3 would be no cpc to plastic light switches.

Either way the main question was regarding what circuits should I be putting on the schedule of tests for a consumer unit swap.

So for me all the circuits should be on the schedule of test results.
No earth at switches is a C2 unless mitigated by warning notices at consumer unit advising only class 2 equipment to be installed at switches
Strictly speaking no class 1 equipment should be installed on circuit & warning notice at CU advising only class 2 equipment to be used

I'm under the impression that you didn't used to need a CPC on a lighting circuit?

As it was compliant at time of installation, only a c3 is required as a minimum?

It is the crux of the issue. I only want to certify the dist board, not every circuit in the house.
If I put the lights on the schedule of tests am I certifying compliance with current regs (which it does not meet)?

If changing a consumer unit you're certifying the consumer unit.
However, as you've changed the characteristics of every circuit, you also need to test every circuit for continuity of protective conductors at a minimum.
If any circuits would not comply to the extent that a C2 would apply to that circuit, then you must not reconnect that circuit until the C2 has been rectified.

If someone removed the white plastic switch and changed it to a nice brass decorative one you would need a cpc.
If you are only certifying the board you still need to include all the circuits in the schedule How far you test them would be in the "Extent of installation covered by this certificate "

All the answers I needed on that thanks!

Complete test sheet, all non-compliances to be listed under 'condition of install' and circuit notes.
