One ring main covering a brand new 3 bed house

Breaks out the popcorn.....

If you exclude kitchen/utility areas what realistically do you expect the "load" to be in the average house for a ring/radial - not much.

Very true. I tend to provide 20a radials for all but kitchen these days.

Mind you, those alarm clocks can pull a lot you know

Problem is, in my view there is no decent alternative to a 32 amp ring.

Two 20A radials

Each to their own I suppose, I'm not trying to start this debate again, like you said I just find most sparks fascination with rings (no pun intended) rather funny

We work domestic, commercial and industrial and it has been a very long time since we last designed to accomodate a ring final circuit!

I'd rather see 2 X staggered RFC's, over a couple of radials!! lol!!:wink_smile:

 

[D Skelton]

I'd rather see four radials ove a couple of staggered RFCs

Nothing wrong with radials IMO, but I would certainely have the kitchen on a ring, or 2 haha, JMO, anyhow however back to the original OP, one ring for the whole house is pretty shocking really, the building inspector must be taken to breakfast regulary to decide not to look at the board and let that go.

Also radials don't half speed up testing, handy when your against the clock!!

He can't really say anything can he, even if he did know what he was looking at, ....if they have approved working drawings based on accepted drawings from his own council planning dept!! lol!!

I pity your customers pockets/Tommy Tank account then ...lol!!

I think the cost of the cable saved by not having a return leg would easily pay for an extra MCB

 

[tom79bmth]

I have never seen a building inspector get involved in electrics or even look at them, they just what a niceic cert and I know one thing I wouldn't give a niceic cert with out it being safe, I have always put 2 rings mains in a 1 bed flat

Haha yup very true

No return leg as such on a staggered ring!!, They'll also be a much larger CU/DB on top of the MCBs!! Overall, you'll be using more cable with radial circuits than with rings, one of the original reasons for implementing ring circuits in the first place!!! lol!! A combination of both types of circuits (depending on the installations requirements) is always going to be the best way to go!! I've nothing against either of them, they both have pluses and minuses, like any circuit configuration!!

Can someone explain to me what a staggered ring is, please?
