Quickie: Kitchen / Diner with separate cct for appliances

[myxiplx]

Hiya,

I'm planning a rewire for a Kitchen / Diner. I've read that it's a good idea to have kitchen appliances on the non RCD side of the CU, to stop your fridge defrosting when something blows.

My question is what's the best way to handle this with a combined Kitchen / Diner?

My idea is to have a circuit running from the non RCD side of the CU supplying only the kitchen appliances, and connecting to the appliances via FCU's.

All the other sockets in the kitchen / diner would be running of the normal ground floor ring main from the RCD side of the CU.

Is this a good plan? If so, what rating of MCB would people advise? I'm only planning on running the fridge, freezer, washer and dryer off this circuit. Would a 20A MCB be overkill?

Ross if you allow 3kw for the DW & Washer you get 6kw = 26 Amps maximum demand. Applying diversity you could argue 20 amps would be ok but I would go for a 32 amp ring or radial final circuit the extra cable cost is negligible against the risk of the freezer going off.

erm

most sockets in your kitchen should be on rcd if its ground floor

it is adviseable to put the firdge and freezer on non rcd and this should be done with a totally seperate cuircuit from the CU

Many thanks, 32A it is then.

Plugwash, the sockets will be on RCD, it will just be the appliances that'll be on a separate circuit.

Are you saying I would be better running just the fridge & freezer off the non-RCD circuit? I've plenty of space in the CU to run a seperate circuit for the washer, dryer (& dishwasher if I buy one later).

That would then give me a non-RCD cct solely for the Fridge / Freezer. A seperate RCD protected 32A circuit would power the washer, dryer & dishwasher, and a third RCD protected circuit would run the ground floor ring.

All appliances would be wired directly into their respective ccts via FCU's.
