Thoughts Please!

Bit of a problem, any ideas?

Kitchen to redo, customer having an induction hob,and an oven rated at 3.5kW

Existing ring main (hopefully) and cooker supply 32A 6. mm

Almost impossible to get to consumer unit, terraced house, solid floor, all laminated nad tiled floors above.

Asked customer to reconsider either oven or hob.

1. Can I feed the oven and hob off the same circuit? Clearly not ideal, and of course I would rather not. I'm aware of diversity etc, but would worry about full load at those times of heavy cooking!

2. Supply 1 way consumer unit, fused at 20 A directly off the ring final???? good work around, but allowed??

Thoughts much appreciated, customers are so difficult at times, this work is for a large kitchen company who sell their customers the world, then the cutomer expects it installed for free.

run oven and hob from the cooker 6mm/32A circuit. use a dual cooker outlet. 32A will cover both oven and hob, ask E54.

Why can't you feed both hob and oven from existing cooker supply?

Depends on the combined KW of both appliances. A 30/32A MCB sitting on a 6mm cable is more than good enough for cooking loads up to 15KW. Connect both appliances to a dual connection plate, supplied from the the existing cooker control unit!!

What's NOT ideal about it?? Worry not, ...it's been done like this for over 60+ years. lol!! When have you even known a 30/32A cooker circuit to trip out over say Xmas day?? I've been around (i would imagine) a good few more years than yourself, and i have never known or seen it!! lol!!

so there you have it. 3-0 for using the cooker supply. almost as good a result as as 30-3.

Cheers guys, noting your name on the cert for helping me design the circuit... knowing my luck there will be a problem with the existing 6mm, don't you love explaining things like that to customers.
