Code for main switch replaced with RCD

[SJD]

On a test & inspection today, I came across an older Wylex split load board that had been modified to add RCD protection for all circuits (see photo). The main switch was replaced with an RCD (despite there being room to add the second RCD to the left of the main switch). So a fault (or RCD test) on the LH bank of circuits trips both RCDs.

I'm inclined to code this as C3, since it defeats the object of trying to provide some discrimination, not necessarily potentially dangerous.

I'm wondering if others would be thinking this is an unapproved modification of a board, and perhaps should be a C2?

The EICR will be unsatisfactory anyway, there are other issues like holes in the front cover, an RFC with open circuit rN, some unearthed metal fittings, etc.

Not potentially dangerous but certainly annoying, new main switch is about £3, a couple of jumpers and you have a dual board. ?

C3 IMO.

I would agree with c3

This is one instance where I disagree with BPG 4.

The only reference similar to a main switch RCD is this, under the heading "do not require reporting":

Installation not divided into an
adequate number of circuits to minimise
inconvenience for safe operation, fault
clearance, inspection and testing

In my opinion this would be C3, due to possible danger of falling downstairs in the dark etc.

Thanks for the replies.

The point from Ioz2754 about being an item noted as not requiring reporting, I'd assume this refers to something that was compliant at the time of installation. I'd like to think modifying a board to put two RCDs in series was not a compliant thing to do at the time it was done.

Indeed. I would agree with this. Why anyone would think this was a good idea....
