oven and hob separate?

[isitnow]

Hi guys just wondering the best way to wire ovens and hobs, I usually see hobs on their own via a double pole isolator to the side of the hob and the oven plugged into a socket mounted inside the cabinet sometimes but i dont really like the thought of that, (although mounting equipment to fixed unremoveable kitchen panels is acceptable)


I know that all terminations have to be able to be visually inspected but just wondering if any of you guys have a better way rather than having to plug the oven into a socket outside the cabinets or mounting one inside the cabinets nearetst the oven,

I only ask as I am not a domestic electrician and the job is for my own home and i want the best job i can possibly do, I have considered wiring an sfcu (nice looking one) as part of the kitchen ring and running the flex from the oven directly through a conduit chased into the wall to a flex outlet cover fitted behind the oven so that the cable can be removed if the oven needs repalcing etc sounds pretty decent to me just need a heads up if theres a better way???? thanks in advance

oh and one of the reasons i ask is that the rented property i am living in now has combined the two via the double pole iso and its a brand new build so i assume it shouldve been wired correctly.

An SFS above with a connection outlet below worktop for the oven would be fine IMO as this is how it's nearly always done.

The only thought to give is that if the appliance is rated greater than 2KW, BS 7671 reccomends it shouldn't be connected to a RFC and should have it's own dedicated radial circuit.

Ah right i wasnt aware it was in the regs the 2kw on a ring final circuit, do you know what regulation that governs this?

It's not actually a regulation but part of the appendices and is informative, but is still good advice.

It is in Appendix 15

 

[Guest123]

App 15.

As I said it only reccomends it though and is not a hard & fast reg.

had a look your right mate to put it on its own circuit it reduces a constant load on one side of the ring, so what do you suggest im obviously putting the hob on its own circuit you recommend having a seperate circuit for the oven aswell?

Personally yes the idea design would have the oven on it's own circuit. But as you say it is a new build and it's rented are you wanting to go to all this trouble of pulling in new circuits, which will then raise the ugly specter of Part P and permission from you landlord.

Is there an existing cooker circuit?

i'd spur off the cooker islolator with a single socket outlet behind the oven. that way you can leave the oven on a plug, and you've got accessible isolation without pulling the oven out. to avoid fitting a FCU, you could spur off in 6mm.

sorry mate i was unclear on my first post im currently living in a rented property but am buying a property very soon and intend to rewire it straight away and by planning ahead im trying to gather a few free materials spare off jobs in work so thats the reason why im asking like i was only comparing to this property being on one circuit as a comparison as this is anew build it shouldve been done to the 17th and part p, but a rewire doesnt come into part p so forget that, although i do intend to wire it to part p the socket and switch heights and the equipment above a worktop being atleast 150mm etc

would you not still need to work out a design current for both oven and hob if all on one circuit though tel? Would he be as well to check and see what size cable is feeding the cooker...and what size breaker/fuse is protecting it?...........

 

[telectrix]

the socket and switch heights and the equipment above a worktop being atleast 150mm etc

you put your sockets and switches at the height that you want them. the 450mm to 1200mm only applies to new build, not rewires.

 

[GLENNSPARK]

It seems to still be a grey area this one tel....my boss and i will only adhere to the 450 to 1200 thing on newbuilds NOT existing rewires...like you say.....

If your going to do a rewire then if your fitting a dual RCD CU then I would wire 2 circuits 1 for hob and 1 for oven. Have one circuit on one RCD and the other circuit on another

Both in 10mm for any future proofing as induction hobs are quite meaty units.

Terminate the 10mms into a suitable CUs. Then 10mm/6mm to cooker connection points, or a double point depends how your kitchen is designed. Remember if you do it this way with a double unit you will need to fit a sticker to that dual supply unit saying that it is fed by 2 supplies.

yes im aware of that mate i could in fact have sockets at the skirting board but i just want to install the equipment at the heights that im used to workling to

cheers mate ye i think thats the plan i do intend to get an induction hob and i have been trying to get manufactures info on the power consumption,yes i was going to separate the circuits on either side of the rcd split, you mentioned a double fed point im assuming thats mlike two isolators in one separate feeds and loads operated by the one switch but with the sticker stating that its double fed?
