Small Shop- CU change

[MvP Electrics]

hi all,

doing a consumer unit change in a small shop only has 4 circuits. did a PIR first, all circuits are good.

problem is that I cant find a small consumer unit that is dual rcd. I understand the whole installation can not be protected by one RCD. Is RCBOs the only solution? It boosts the material cost from £60 to £120ish.

any advice would be great.

thanks

Mate i would go for RCBO's or if there aint a computer on the circs then main sw rcd, also depends on what the 4 circs are doing

I always fit RCBOs to CU changes, you should be ale to pick up a board and four rcbos for around £70

I agree, RCBOs are the way to go.
I know a lot of the leading brands are abou £30 per RCBO, but there are a lot of cheaper alternatives.
I suppose it depends what wholesaler you use.
I pay £10 per RCBO, I would prefer to use merlin or mk, but would never get any work, and at the end of the day they pass british and EU standards. (it all depends on the customer).

My supplier sells CED, but there are many other brands in the same price range.

I agree wholeheartedly,my friend,but they are not all governed by british fire standards....Again,insurance taking us all up the wrong road....
