EICR - 2 boards, 1 with an off peak split and one with regular supply

Hmm, very strange.
Here we have two installations and the advice is to put N/A for Main switch details?

I think Spin is saying that two CUs from one single supply is classed as two installations.

A great attempt at trolling but not good enough to catch me out.

3 Phase supply into the basement of a building.
Ground floor shop, first floor flat, second floor flat.
One supply, how many installations?

Oh yes, and of course there’s also the fact that a single installation can have more than one supply

The origin of an installation is the consumer connection point at the meter.
2 meters, 2 installations.
1 meter with 2 connection points, 2 installations.

so does that mean that this flat actually has 3 installation what with the board that has one side regular supply, other side off peak, and then another board regular supply?

Are these 3 boards connected to different connection points on the meter, are there 3 meters?

 

[Neon Vagabond]

i'll need to double check tomorrow

It’s unlikely that there would be 3 installations.
Usually there’s just one normal supply and one off peak supply.

 

[Resu]

In this scenario, 1 install, 1 certificate, 2 boards.

There are plenty of RCD mainswitches in Scotland, where an inline RCD has been fitted to the tails before the board as an easy way of complying with the regs back in the day (although less than ideal now).

Another example would be a TT installation with a time delay RCD upfront.

Oh dear, what a string of posts. OP, ideally you need to get experience working alongside some other electricians experienced in carrying out EICRs. C&G 2391 is the current qualification in inspection & testing covering both new installation and EICRs. Guidance Note 3 is an excellent purchase to help improve your understanding.
I understand why some get hot under the collar when electricians with limited experience in I& T jump in without sufficient support, given that you are certifying/reporting on an installations suitability to be energised/suitable & safe for continued use.
The best advice I can give someone involved in I&T is to read, understand and apply the standards/guidance available, understand what you are testing for and why, know, understand and be able to interpret the results you obtain, and never forget that a poorly designed, installed or maintained installation can lead to serious damage and/or loss of life. It’s not to be taken lightly!
Here endeth my sermon

We do a lot of EICR's and I see some by local registered contractors that say things like 'no power - cannot test' (apparently they have not heard of dead tests) and 'needs a rewire'- which may even be true but is not a defect on BS7671

You are not doing EICR's for landlords are you?
