new cu chhoice for mall 1 bed flat

Hi

I am intending in installing a non split board for this. I cannot see point of having dual rcd in such a small installation.

Anyone disagree?

when i had my first year assessment for elecsa i rewired my one bedroom flat.i had three circuits in total on one rcd and my assessor told me it was non compliant and that i had to still put it on a split/split board!!

 

[martinxxxxxx]

maybe i'll put an rcbo in for the lights

Or RCBO's.

I was thinking just one for the lights.

By not having a split board I know it is contry to having the circuit arranged in an order not to cause nuisance but that the only reg if so I think I am justified in interpreting it as I have ,ie the install is so small that it is not unreasonable to have them on a single rcd

You cannot have the whole installation protected by one 30mA RCD. The regs do state this (in a roundabout way.)

If there are only 3 or 4 circuits then a CU with a standard main switch and 3 or 4 RCBO's will still work out similar in cost to a dual RCD CU.

Agree with Jason id put a wylex 5 way non rcd cu in and run rcbo's.

Just done small bungalow exactly how jason said!!!! Its ideal

This would be my choice as well. Just done 6 flatlets using these. the Wylex boards are great with loads of room to work in and still stay tidy even when it is full of RCBO's.

As already stated, RCBOs are the way. I think the high prices of RCBOs is what puts poeple off, but the prices are starting to reduce. In some instances, quite a lot.

Surely if it is not explicitly stated anywhere then I am within my rights to have one rcd protecting the whole lot after all it is not as if there is a safety issue at stake here.

I have 6 circuits;- shower, cooker, ring, appliance radial, water heater radial and lights.

Would it be really non complient and if so which reg would it be in contravention of?

I believe if anything I can meet the requirement to minimise disruption of other circuit by just putting the lights on their own rcbo. and not running through the main rcd at all.

I havent got my book to hand at the mo, but it is in there somewhere.

I wont be home for a couple of hours so ill have a look then, but maybe in the meantime, another member may be able to find something.

 

[martinxxxxxx]

OK OK
I have come to my senses, opinion seems to be divided; me then everyone else. sooo, I have sent back the 8 way and the RCD and ordered a dual rcd 17th board to get the job done.

However I still am not totally convinced that the use of one rcbo on the lighting and a rcd serving the rest of the board cannot fulfil the requirements for a small flat.

I am going to get the book from the van.

Anyone up for a debate later.

You will not achieve discrimination between the 2 RCD's.

If the main RCD went then you would loose the lot.

If the lighting RCBO went, you COULD still loose the lot.


Sorry, i was meant to look that one up for you.

Not if you run the rcbo straight to the main switch, will you?
