NICEIC Certification Scheme NICEIC online form confusion

Bob Fleming · Jan 26, 2022

I am constantly confused by the online installation form and what they refer to as "main switch", and "installation worked on". If I have the following arrangement, on a TT system:

[ElectriciansForums.net] NICEIC online form confusion

Which is the "main switch / switch fuse /breaker / RCD" referred to in part 8? 100mA RCD, 45A Switch fuse, or the Consumer unit Main switch?

Then which device is "supply to DB is from" when it is not connected to the origin? 45A switch fuse with the 100mA RCD as "associated RCD"

Or should I add the 45A Switch-fuse and SWA as a seperate circuit or DB, as otherwise there is nowhere to record the test results?

Many thanks in advance!

Bob.

the red pully thing on the fuse board ,not the rcd .

In the scenario you pictured, the 100mA RCD is the main switch, which feeds a switch fuse, which in turn, feeds a consumer unit as a sub main. This is the correct way to record it, ie the switch fuse gets its own row at the top of the schedule of test results.

In reality, what usually gets put down on the certificate as the main switch, is the one in the consumer unit.

Agree It’s a Rcd for main switch, it’s not directly connected to the supply.
The DB Main switch refers to the cert your working on ie: the DB.
I also agree it can get a bit confusing

I have been having a conversation on site recently :

In a factory situation, main intake room which contains the metering equipment, there is a 315A, 60947-3 switch fuse. This feeds a section board complete with MCCB's, which in turn feeds 10 sub boards dotted around the place.

When completing an EIC, for a newly installed circuit, fed from one of the sub boards, fed from the section board, fed from the switch fuse, which point of isolation are you inclined to put as the "main switch" on the test certificate?

I argue its the switch fuse in the intake room, a colleague says the main switch of the DB from which the new circuit originates from.

Apologies if this is a bit out of the blue.
