Posted By: philedgeQuoting from a previous page doesnt seem to work for me…It doesn't work for anybody. The workaround is to quote any arbitrary fragment of text from the current page, copy and paste the text to be quoted from the previous page (opening the previous page in another tab, of course) then remember to change the name of the person being quoted. Actually, change the name of the person first to be sure.

Posted By: philedgeAdding an RCBO would give a single circuit RCD protection but leave everything else in the CU without protection, assuming a CU without any existing RCD protection.
Posted By: Artiglio( the theory when they were installed 2002-4 was that it was more dangerous plunging a house into darkness ( people stumbling about looking for cu etc in dark) if a bulb blew than any likelihood of an electrical injury from a lighting circuit).That's something that's changed, of course - it's usually incandescent bulbs which trip RCDs on failure, LEDs not so much AFAIK, so having far fewer incandescents around swings the argument towards having RCDs on lighting circuits.

Posted By: Rexfuture owners are unlikely to be electric car owners,Are the existing occupants car owners?
Posted By: philedge…theres nothing to stop you fitting a section of DIN rail within the existing enclosure and mounting RCDs/MCBs/RCBOs onto the DIN rail. Youd need to get somone to fabricate a steel cover.IIRC, enclosures (for all connections, not just switchgear) need to be to a certain BS.
Posted By: RexSo no other option than to remove some bricks.What about the option owlman suggests? Lots of boat and US domestic circuit-breaker panels have the breakers going left/right rather than up/down. The cover relies on direction of the gravity or acceleration vector, though.
Posted By: philedge…unless theres some specific domestic requirements??There are specific domestic requirements, see further up this thread.

If it was mounted sideways then it'd need to be modified to latch the cover closed to meet the relatively-recent BS7671 for domestic switchgear enclosures but then it would no longer be certified to the other BS for all wiring enclosures.
Posted By: philedgeIs there a section in the wiring regs that specifically states domestic CUs must have a gravity closed cover??No, AFAIK there isn't and I didn't say it wouldn't be compliant, I said it wouldn't be certified to be compliant on the assumption that any modification would invalidate the certification.

The idea of having to stand there and hold up the front cover whilst I look at the innards and do whatever else I'm doing fills me with horror.
