Electric Cooker / Hob

[dieseldog1964]

Three questions.

I have a 5.8Kw hob to install.

1) Can this be wired into the same junction box as my 5.5Kw double oven?

2) I make 5.8Kw + 5.5Kw equates to a 49A MSB. Would a 50A do or should I go for bigger ?

3) Would I be better off wiring a seperate radial circuit direct to the consumer unit?

1. possibly. though was there a hob there before? If you had gas hob before, take the electric one back right now and swap it for a gas one. You will sorely regret the change to electric, until the day you fit a new gas one - electric hobs are pants, and are much less efficient. What size cable is there, supplying the oven and cooker switch? What size MCB is it on? How far from the origin is the cooker position?

2. hob = 25.2A oven = 23.9A. A 40 amp MCB would suffice - applying diversity a little bit here, since you wont be using everything at once, but the official diversity rule for cookers brings the rating down far too low, IMO. What's an MSB?

3. This is by far the best way - a seperate 32A radial for each appliance.

Perhaps an MSB is a Miniature Sircuit Breaker

JohnD,

Did you work that out yourself? I'm impressed !!

But does your mam know you're up this late ?


To Crafty1289 : Thanks for the advice. For information, an MSB is a Miniature Circuit Breaker when you've just returned from the pub.

haha... I get the idea:

If I install a separate radial circuit for the hob instead of wiring it to the terminal box on the oven circuit, does this mean I have to put in another terminal box and control unit for the hob circuit ?

yes, im afraid so. It wont look too bad if you go with a single-gang-width unit for both.
