One ring main covering a brand new 3 bed house

[dickiegeorge]

Today my sister moved into a brand new 3 bed property. I looked at the distribution board and found that it had one ring main serving the kitchen, GF and 1st floor protected by a 32 amp mcb and a 80A 30mA RCD. I know that you can theoretically have unlimited sockets on a circuit but is this acceptable design? Does it conform with regs? It serves 25 points in the house

Appalling, I always have 4 rings, up, down, kitchen general use, and kitchen appliances, but thats me, over the top maybe.

+1....

No it doesn't meet current regs, no segregation of circuits. Needs to be at least one up and one down. Any good spark would do that plus put the kitchen on its own.

 

[Johnuk]

yes poor design by that spark

 

[Octopus]

Bad, bad, bad. Are you saying there is one up front RCD protecting ALL the circuits?

 

[monkeyelectric]

Thats shameful, should b at least 2, preferably 4 as Mike has said

 

[R&M]

I believe it's really bad practice but I can not think of any Reg to say it is against that. But it is against Approved Document P I think.

Check the BGB (thats on the basis that theres 1 rcd)

I've heard a few lads noticing this in new builds lately. Seems to becoming common.

If you look carefully outside you can probably see where the installers horse stood! Usually go for 3-4 ring finals on our jobs

Thanks for everyone's replys. It's a split board, one RCD covering 4 mcb's which are lights up, lights down, heating and cooker. Other RCD for the one mcb protected ring main. I'll advise her to talk to the builders about it but is it too late?

Too late, probably. Builder guilty of cost cutting - 100%

^^^^^^ can someone post up the reg numbers about this statement, just so wrong. I would do it myself but I no longer have the patience

 

[Jimmyb]

A ring circuit is allowed to cover an area not exceeding 100m square.

What's your floor area where this circuit covers?
