UK Domestic kitchens

[Toshie]

When wiring a domestic kitchen is ok to supply integrated appliances from 32A/ 2.5mm ring via 20A D.P. Multi grid Switches , using 2.5mm on out going side of switches to a 1 gang socket or spur ?

Yes, subject of course to the normal loading considerations for ring finals.

And BTW - you don't need to use 2.5mm² on the load side.

That’s how a lot of new builds are done. Although I think there’s a few on here who don’t like using 20A DP switches protected by a 32A ocpd.

Are you putting in a ring solely for the integrated appliances?

Consider radial circuit for each appliance over 2kW. Can still use the same bank of switches, but more than one circuit supplying.

Some appliance manufacturers specify a 16a over current device. So if you are strictly following the M.I then putting the appliance directly on a 32a ring is not correct.
of course the appliance will work hardwired directly to the 32a ring and I have done this on occasion but technically it’s not correct unless fuses down to the correct rating

Yes, usually those appliances that are designed for EU where the 16A radial is the norm.

Do they mind using BS 1363 sockets which only have to cope with 20A in the cable?

I don’t know, it’s not something that concerns myself. Have same set up in my house, and I don’t see any issues personally.

A grid switch set up is totally compliant. It’s just spurs off an rfc.... although branched off very close together within the same box.
As with any infused spur, you can feed a double socket... but not usually done in a kitchen environment... single sockets only.


The above is for a “standard” rfc 32A OCPD
