Ring or radial in bungalow

[Brightonbill]

I’m rewiring a bungalow and the owner has asked for a radial for all sockets except the kitchen. But there will be a separate washer and dryer in the circuit. Will a 20A radial be enough?

When you say "a radial for all sockets except the kitchen" it implies an RFC for the kitchen, in which case 32A is fine.

Or do you mean a ring (RFC) for all others, and radial for the kitchen? In which case you could do a radial in 4mm and (subject to method) fine for 32A.

I read this a few times. I think it is two radials one for the kitchen and everything else on the other.

My read is that a single 20A radial is to serve all sockets outside the kitchen, which includes washer and dryer (presumably they're located outside the kitchen).

Not sure why the client is responsible for design, but I'd be advising them along slightly different lines.

It would be great if the OP could clarify this.

I’ve started on a bungalow refurb too for a farmer.
He just wanted a new kitchen, new board and make sure the rest is up to scratch.

At the moment there’s only one single socket in each bedroom… 2 in the lounge. Only one socket circuit, only one lighting.
Am adding more, with kitchen on its own rfc. Splitting the lights into 2 circuits. Adding smoke and heats… extractor fan, point for a boiler… and taking out electric shower. The cable for that I might reroute into the kitchen and use as supply for lollipop ring.

I noticed yesterday somebody nabbed all the old lead cable that was lying around.

Yes. The kitchen to be on a ring, and the rest of the house on a radial (except boiler etc)

Sorry a bit of additional info. The reason for the radial sockets is that he’s doing all the chasing (great) but wants to minimise it because he’s living there during the rewire

How does it minimise it?

One chase per point not per cable and even with rads you're looping.

So are you saying the washer and dryer is a 20A radial.

 

[Brightonbill]

Anyway, the central question is do we think a 20A radial for sockets would be adequate for a bungalow given that the washer and dryer would be on it plus all the other usual loads (kitchen would be on its own rfc)

In practice it's likely to be fine, but that's not to say that I'd design it that way.

This is a bungalow with easy access in the loft from the consumer unit to the tops of all the walls? Then you can have as many radials as you want! For example a separate radial for the washer & dryer, or even a radial each if you wanted!

 

[Brightonbill]

Thanks for the suggestions. I’m now thinking to split it with a radial for the “utility” and the remaining sockets on another radial.

Separate radials for the heavy loads like washing machine etc
