hi Guys

Couple of questions if help could be advised.

I have an electric oven and electric to fit. I should have ratings sent pretty soon from work. I have seen some of these new cookers now and on the backs they state 7kw fit 32amp supply. Is this a bit of the norm these days. I have been used to fitting 10mm T&E to a connector unit and 10mm T&E from there to the cooker. In this senario now surely you can just run 2.5mm T&E seprate supply back to board.

Where the cooker and hob are seprate I know the regs state you can use one main switch to control both appliances what do most of you guys do in this scenario. I assume most seprate oven and hobs now come pre wired with flex, please correct me if I am wrong. Also will two flex's be fine from the one control unit. behind oven. Just some clarification please all this would be nice. I have been flicking through the O.S.G, still cant find that bit about the distance between sinks and outlets.

regarding placing the kitchen items sockets and spurs. I have 2 x double sockets to install plus the cooker control unit and a spur for the washing machine. problem is space in this kitchen.

the units measure from left to right cupboard at 400mm, then cooker and hob above it ie 600mm, then cupboard at 400mm, then cupboard with bowl for sink in at 600mm, then washing machine at 600mm with drainer it looks like above. then there is a side wall.

need to fit the above items somewhere above this work top area. I know you cant have sockets with in 300mm of the sink, does this include drainer or just the bowl section. Also is there a distance from hob where outlets can be placed, not refering to max distance of cooker switch from appliance.

Did I read you wrong or are you suggesting that 2.5 is ok for 32A????????????????????????????

Here you could hardwire from the CCU to two seperate cooker outlet plates. Much neater and tidier than 2 flexes into one plate.

There never used to be an actual rule but I think my field officer mentioned it at my last assessment. Maybe its in the E.G.B.R

Thats gonna be tight, especially with the cooker switch on there aswell!! Good luck with that one....

If you actually find that distance reg, please let me know..

No, I can do voltage drop.. I mean the sink to socket distance....:)

Sorry see the question now,

It's in Electricians Guide to building Regs (Green Book) Page 61. 5.5.2

Haven't been able to find it in the Regs (I have a feeling that's it's not in there, I'm sure someone will correct me if I'm wrong)

Hope this helps

Jim

There is no reg with regards to sockets distances from sinks, although as stated, its in the EGBR.

I seem to remember it was an NIC thing originally.
 
regarding the 2.5mm senario i mentioned earlier. That was supposed to have been typed as a seprate ring (ie making cable now 5mm blah blah) or just use some 4mm as a radial. Yu cant have single 2.5mm T&E on no more than a 20a radial.

Cooker control unit then. most of you would run 2 x 10mm cables from the unit down to the outlet plates one for hob one for oven. that sounds like it would be difficult to get the cables in terminals on back of unit.
 
A ring final circuit must not supply an immersion heater, storage heaters or a cooker rated more than 2kw. p362, 433.1.5

So therfore you should use a radial circuit.
