extending a ring circuit

Hi All,

Im currently (very slowly) putting a new kitchen fit in.

In disscusion with my electrician I would like to run a dedicated ring to the kitchen but this may prove a problem due to the routing of the cables to the cu.

So I was thinking of extending the ring from an exsisting socket. taking a feed from say socket 1 on the right hand side wall and taking it under the floor and working from left back to right install new sockets.
Ending back on the right hand side to complete the ring.

I have checked this site (and others) and it seems reasonable.

The sockets I intend to install are

1 x left wall for dishwasher (maybe not havent decided on the luxury of dishwasher)
1 x socket front wall for extractor/chimely fan
2 x socket right wall for toaster ect

The oven will be gas so I should be able to plug into exsisting socket to run the clock ect
Hob will be gas.... I am assuming that a hob requires a pwr source for the electronic ignition, is this correct ?

Please guys feel free to give me advice and point out any errors

Cheers
Geordie

Regulation 130-07-01
‘No addition or alteration, temporary or permanent, shall be made to an existing installation, unless it has been ascertained that the rating and the condition of any existing equipment, including that of the distributor, which will have to carry any additional load is adequate for the altered circumstances and the earthing and bonding arrangements are also adequate’.

Then there is Part P

Work in a kitchen is notifiable, as are changes to an existing circuit that will affect its design characteristics.

Did you mean to reply:
generally a kitchen is given its own ring because it can draw quite a lot of power. Also, a ring is designed so that power draw will be spaced evenly around it. Adding a kitchen right on one end of a ring can mean that most of the current gets drawn just from the cable with the short route back to the CU, which can theoretically overload it. There is a maximum cable length which can be used in one ring. In practice, you would get away with having every single socket on an average house on one 32A ring. ?

So, subject to the provisos about overloading and unbalanced loads, then yes, you can split a ring at a socket and extend it.

Is there other power already? If so, can't you use it? But also if there is, beware the dangers of having two supplies to the same room, in case someone only switches off one and then thinks everything is safe.

Thanks guys,

Yep I know its part p. Thats why the sparkie will do the work.

I just mulling over a few thoughts thats all, If I can get a cable run to the kitchen and cu and back I will do that (but it will mean upgrading the cu as there is no spare circuits).

Plus if I do put a new ring in.... how would I remove the one socket on the kitchen side ? (the kitchen is divided into 2 parts, kitchen area and dining area if that makes sense).

If I put in a new ring I will mark the cu to tell future housholders that there are 2 rings in the kitchen/diner.

Just thinking of the best way to budget the upgrade !
