Eicr 1361 fuses 3phase circuits from db

[Silly Sausage]

Phoned the nic today got told that it's a c2 and it's regulation 537.2.2.5

Hmmmmm.
The second part of that reg states "...but single-pole devices adjacent to each other are not excluded."

No Code.

No Code.

but would EAWR not override that?

Somone must have come across this before on here?

As far as i remember from my day's in an industrial environment, virtually every 3 phase socket circuit were fed via BS 88 fused 3 phase DB's. lol!! Now as far as i know, EICR's are conducted to conform with BS 7671. I can see things getting very confusing if you start applying and/or including other regulations to a BS 7671 EICR format!!

Lets not be pedantic eh a minor slip up on my part I stand corrected

He is not really being pedantic

As an Act has to go before Parliment before it becomes law, a Regulation is something that can be passed by a Secatary of State to become law

Which specific problem do you have with the circuit:
That unlinked SP fuseholders are the means of isolation or switching?
That the fuselinks installed are inadequately rated (e.g. for voltage) to protect the circuit?
Or that the OCP is not linked across the phases as it would be in a TP MCB?

If the latter, I am not sure the NICEIC people understood your query. You would be in trouble if you tried to C2 every TP circuit fed by HRCs.

Check the EAW regs, I am fairly certain that you should have a means of disconnecting all your line conductors at the same time. i.e 3 pole linked switch.

E@WR 12 (2) In paragraph (1), “isolation” means the disconnection and separation of the electrical
equipment from every source of electrical energy in such a way that this disconnection and separation
is secure.

Nothing about simultaneous disconnection, so just pull the fuse...times 3, and hide them!

Thanks for that, was wondering what the difference was.
Saved me googling!

I was going to say that, but hey ho no harm done is there
