my house rewire kitchen circuits help

[Guest112]

Hi guys started a thread recently about my house rewire which im starting soon but i still have some issues,

as ive said in the past i very rarely do domestic work so thats the reason im asking but here goes...

im just after a bit of info and reassurance on kitchen circuits im getting an electric cooker and hob and will be putting both on the same circuit obviously calculated but the reason being the one isolator and saves having the oven on the kitchen ring.

my freezer is going in the utility room and im happy for that to be on the downstairs RFC not the kitchen one but the kitchen RFC will have the hood, fridge and washing machine and the general sockets above the worktops on it which i think is fine.

Also i know its a recommendation to have spurs above the washing machine and fridge for easy isolation rather than having to pull the equipment out to unplug it but not very good looking to have spurs in your kitchen IMO

Just looking for reassurance or feedback or alternatives and will be greatly appreciated

If you had a 5+5+3, you could put in a radial for the freezer on an RCBO on the unprotected side of the CU.

The whole idea is to stop the freezer loosing power if there is a fault elsewhere in the house.

Or has someone already suggested that?

:dizzy2:

 

[jase]

is this common practice now then? i always just put everything on the kitchen ring albeit the cooker of course

Guess it depends whether the sparks is doing the work for themselves, friends, family, someone who has requested/been sold a non-RCD radial, or a client who doesn't care/know but just wants it done for a good price.

When I do my girlfriends kitchen in a few weeks I'll sure as hell be putting the freezer on a separate radial. I'm not having her blame me if the RCD trips and ruins all the food!

On the subject of non-RCD socket circuits, I'm running all the electrics through a store cupboard to the new kitchen. They're not going to be below the surface, but running through surface mounted trunking. Do I have to protect the non-RCD'd cable with an earthed conduit in this case (ie.clearly visible cable)

 

[MNR]

I always run a separate fridge/freezer feed and separate boiler feed if this is in kitchen.

and the fridge on its own radial id have to buy a different db to have the non rcd circuit can anyone recommend a good db at a good price atm i was looking at the 13 way split rcd with 10 mcbs from screwfix for £100 quid like????

Crabtree 3+5+5 or 2+6+5

Should hit your budget from a wholesaler assuming you are trade

 

[jase]

so presuming you put freezer on seperate RCBO? unless you run it surface or in earthed metallic conduit etc etc, and freezer does trip out, you're not going to know until you open the door and woosh, out comes all the melted ice!!! where as if it is on with ring then the likelyhood is that something ie loss of power alerts you to the trip has gone, bit like the old smokes on lighting circuit argument

 

[Spudnik]

Very true.

Dare i say, i have never put them on a separate radial.

hi guys cheers dor all your help im going to do the grid switch method and cant for the life of me find where to buy them.

ive found the grid 20a dp switches are they the ones? im assuming 20A is fine on the ring because the way the load is disipated arounf the ring like???

 

[telectrix]

you need the 20Aswitches, a yoke, and a faceplate. you can get them ready labellede.g. washer etc.

 

[Guest112]

cool, sorry tel is the yoke the metal grid to hold the switches?

yes im looking for one now that says washing machine and fridge like.

Is this method ok then mate the two switches would be linked out on the supply side to be part of the ring and then two 2.5 t+e one going to each single socket, i know its alright to have an unfused spur off a ring gioing to max one outlet each like which is what im doing like and each point will only be able to pull max 13A befor the fuse in the plug top goes like i cant see anything wrong with this method any problems you reckon?

 

[telectrix]

the yoke is the mount for the switches. , and yes, your method sounds right. on e tip is don't buy cheap crap. they fail. use a reputable brand.

 

[Rauer]

You seem to enjoy using the word "like"!!!!!

 

[Guest112]

haha i think its a welsh thing like lol

cheers tele yes i always use good stuff all going to be mk in my house mate

 

[Guest112]

anyone know where you can get labelled grid covers need one that says washing machine and fridge ive tried screwfix and toolstation and a few local wholesalers near me havent tried newys yet anyone get one recently??/?

 

[Rauer]

Never seen labeled grid covers, only ever seen engraved switches

 

[Guest112]

ah right ill look for them cheers mate

did a kitchen/diner recently and split it into 3 rings.

1-Utility ring (washing machine, dryer, microwave)

2-Main kitchen ring (worktop sockets, dishwasher)

3-Diner ring

MK labelled grid switches

^^^^ whats this all about!!!

anyway search for MK Logic Plus Grid System

 

[jase]

just an after thought here, I have seen this grid method done but i thought that the cable feeding a spur from a ring could not be any longer than 1 8th the length of the ring? i'm sure i have read that somewhere

thats too many rings for me mate the whole house is on one atm on a 30ma rcbo and nothings tripped/overloaded

cheers for that the link censors annoying lol

 

[SparkyDips]

use MK products alot, very nice quality and design.
