Installing a double oven - Some questions ??

[caz1562]

This is my 1st post so go easy on me

The single oven I have is dead, so we've ordered a new double oven. I removed the oven unit & modified it to suit the bigger oven. The power supply for the single oven is just a 13A socket into the 32A socket ring circuit. The new appliance requires a 30A supply so I know the existing supply is rendered useless. The plus point is that I'm also converting my hob from electric to gas so the power socket will no longer be required.

The questions are.......

Can I use the cooker socket to supply the new oven ? (this has a single 32A on the distribution board)

If so - What size of core cable will I need ?

Can I use the junction box for the hob to join the new cable to the oven ?

Any comments would be much appreciated.

BTTT

One other thing - I've read that theres a requirement for the CCU to be within 2m of the appliance. My hob is OK but my oven is a good 3-4 metres away.

If that is the case and I can't use the current switch then I'll have to install a new one. The problem is where do I install the new one cause I don't have any where that would be near a wall.

So is the oven free-standing in the middle of the room?

Due to the room layout L-shaped, the oven sits in the corner and is surrounded with cabinets so no walls are in view (if you know what I mean)

Just been to B&Q and seen this :-

This means I can utilise the double socket to the side of the oven and replace with this.

But where is that double socket? You said you had no walls within 2m..

 

[caz1562]

its inside the wall unit next to the oven housing

A switch inside a cabinet doesn't really meet the requirements for accessibility, but you wouldn't be the first to do it....

OK m8 - what about the cabling size ? Am I correct in stating 6mm should be OK

The guys who fitted the kitchen have sockets inside a few of the units (fridge, freezer, dishwasher, washing machine & tumble dryer)

What about the dist board - I've a spare 40A & a 32A trip.


thanks again

6mm² will be more than adequate - it's only a 17.7A load, so on a 20A breaker you could use 2.5mm² if you wanted. I note though that the oven maufacturer specifies 30A, so you'll need 6mm² on your 32A MCB.

You see that's what happens when you let kitchen installers design and install electrics - they mess up.

cheers m8 - I have noted they must have been fly by night cowboys.

Its only now that we've found out the they built the oven unit wrong


Thanks for your comments

Just one thing - In ur opinion, would the socket be OK in the cupboard under the oven ?

Doesn't look like you have much choice....
