EICR Main Switch/circuit breaker

[eddiecme]

Morning guys,
I'm just after a bit of advice. I carried out an EICR on a commercial premises yesterday (no periodic since 1995). 3 phase out of the meter into Henley blocks then split between 3 distribution boards. Two single phase (one old 7 way rewireable wylex board and one single way proteus board) and one enclosure housing only a 3 phase mcb feeding an oven.
What is best practice to record in the main switch/circuit breaker on the EICR? They obviously don't share anything common apart from the 1361 cutout fuses. Any help would be appreciated!

Do the 2 units at the bottom of your picture have cover?

In what respect?

Well have you removed the covers for inspection purposes? if the don't have covers at all I would be more concerned with that issue, than what main switch I should be quoting in my EICR.

oh sorry, yes, the covers have been removed for the inspection, it wasn't found like that!

It has no single point of isolation, there is no Main Switch so you will have to enter "None" or "NA" and make a note in the recommendations.

Looks a right lash up the conductors between the Hager mcb and the trunking are not suitably enclosed.

Yeah it's a bit of a mess, there were a lot of faults on the general standard of wiring and IP ratings. With no single point of isolation would this go in as C3?

 

[westward10]

That is up to you.

I wouldn't code it.

C3 improvement recommended I always like to see an installation with a overall main switch.

 

[Leesparkykent]

Code 3 IMO.

If I were doing the EICR for an insurance company, who have less than intelligent conditions of addressing all C3s, then it would be no code as the switches are all in close proximity, if it were being done privately then C3 on the schedule of inspections as this would be a recommended improvement for safety. N/A on the installation details and each individual main switch identified in the schedule of test results.

I don't really get that what difference does it make. Whether someone ignores the C3 is not a reason for not including it.

If there is a minor recommendation for safety that will cost a customer significant sums to address for minimal gain I feel this is counter productive and not a professional approach. Having someone aware of an issue that could be addressed at a time something else is being changed is good, forcing someone to immediately and without fail to install a single main switch for close grouped boards is not good.

appreciate your feedback

thanks for the response guys

There was a section on the single point of isolation recently in the mag we get from napit, it's page 32 in issue #1 2017 for anybody that hasn't binned it yet.

Their view is that although yes it is good practice to have an isolator at the origin it is NOT required by BS7671 and so no code is required.

How have they explained side tracking Reg 537.1.4

I'll get the scanner fired up..........
