What's your preferred method of feeding several new items in a new Kitchen?

[Argos69]

I'm after the current best practice advice from you guys about an installation I'm looking at.

I've been out of the trade for quite a while and have just renewed my Part P etc and am getting ready to get stuck in.:gunsmilie:

I've been asked to look at a new Kitchen, where there is a requirement for a couple of ovens, hob, island unit stuff, a few fancy cupboard lights and some electrical odds & ends.
The consumer unit (which is up to date, as is the house Earthing) is probably a good 30m away from the kitchen, so I can see a lot of cable to feed a new ring and the other stuff as separate circuits.
Is it acceptable to run a bigger cable to a subboard, then feed the Kitchen stuff, or should I be looking to run individual cables all back to the main CU, the route involves a lot of fiddling about, so I'd like to minimise the number of cables if possible?
Setting aside volt drop issues etc , what's your preferred way, or is the subboard even a realistic option?

Like I say, it's been a while and I'd be grateful for your thoughts.

Thanks in advance for any help!

Have a read of this thread as it was covered only about a week ago.

Completely depends on the ratings of the ovens and hob, and the amount of other appliances used.

Sometimes a single ring will suffice with spurs above hidden sockets and a separate cooker feed.
Sometimes a separate ring is a better option to supply all under counter/built in appliances, and sometimes the cooker can be supplied from this circuit, sometimes not.
There is always the option of a "wiring centre" grid switch instead of spurs/dp switches for hidden sockets.

It really does differ each time for me. Consultation with the client is important on kitchen design as there are that many options to consider for functionality of use and aesthetics.
e.g. under cupboard lights. Do they want to switch them by reaching under or with a wall switch. If a wall switch, do they come on altogether or separately ?

Cheers guys, the Kitchen job is still very much in the "talking about it" stage, it was just the distance back to the CU made me start thinking if there was another way I should give some early consideration to.

 

[Andy78]

If it's at early stages see if you can get some early ideas from customer.

i.e. Do they want a plug in fan oven or a whopping great electric only range ? Do they want a CU in the kitchen on show ? could you hide it ? would it still be accessible ? Is cost a problem, do they want the cheapest way or the best way ?

I'm having trouble believing there is 30m + between the CU and the kitchen. The floor area of this house must be bloody enormous!!.....

That's a bit of an estimate. I get 25 good paces from the CU (by their front door) all the way through to the new Kitchen extension. Looking at their solid floor, I also guessed I'd end up going overhead, so added 2.5m each end for that. So I reckon I'm roughly about right-ish. Yep, the house is big - I could live in their Garage! And "No" I don't know why their CU is beside the front door, when the've a Garage which would be a great place to put it!

if the garage goes back a fair way, it might be an idea to fit a 10mm 50A sub-main towards the rear of the garage, then feed kitchen from there.

Yes, I like the sound of that, as the Garage/workshop extends most of the way down the side of the house and would make a nice short run for the rest of the cables! Cheers for that.

Is there any method required to feed the new items in a new kitchen!! I think all the items will be placed in the place where they should be kept. Because in kitchen for every accessory the place are finalized previously.
