Kitchen RFC

[Spudnik]

Chaps,

Not got my regs books to hand at the mo, but could anyone find anything that states a kitchen MUST have its own RFC and if poss, a reg number to back it up?

Ta very much..

May be forced to eat my words but AFAIK there`s no such reg J - good practice but not a must

Will look now just to check tho

I dont think there is one jay but think this one falls under circuit design and circuit loading as most kitchens now have too many appliances to be included in the house ring main but dont need to teach you to such eggs i assume your trying to proof a point to someone.

 

[sparkswillfly]

agreed

Thanks fellas,

Yes i am kinda trying to prove a point, although the circuit design option sounds like a winner, especially as i am sure there is something about that in the OSG??

Dam customer know it alls

no but your ring final must provide reasonable sharing of the load and musnt exceed 100metres which is why i would normally wire a seperate ring for kitchen in a larger property.

appendix 15 433.1.5

Expanding on the last post...

17th Edition GN1 > App.C2.1 (page 128) - remember that GNs expand upon BS7671)

"The floor area served by the circuit is determined by the known or estimated load but does not exceed given values.

An assessment of the loading must be made for the design of an installation, in accordance with Chapter 31 of BS7671, & adaquate circuits provided (also see Reg 132.3 - which is quite generalistic BTW)

For household installations, a single 30A or 32A RFC may serve a floor area of upto 100m sq. but consideration should be given to the loading in kitchens which may require a seperate circuit. Socket outlets for washing machines, tumble driers & dish washers should be located so as to provide reasonable sharing of the load in each leg of the ring, or consideration should be given to a 4mm sq. radial circuits."

That section of the text.... "Socket outlets for washing machines, tumble driers & dish washers should be located so as to provide reasonable sharing of the load in each leg of the ring"

...has also been borrowed by the green book - an official IEE publication covering electrical work re: Building Regs, which your charming customer should know is THE LAW.

So as it states it, i`d take that to mean it`s Statutory.

Hope it helps ya

Thanks for your input.

All sorted now

It's better to put the kitchen on it's own circuit as said due to the nature of equipment in kitchens now.

Sometimes it may have to have 2 circuits if there is a washing machine, tumble dryer, dish washer and any other large consuming machines fitted in the kitchen as you don't know if they may be switched on at the same time.

How about Section 314?

 

[gunner]

have you considered putting the kitchen on a radial
