Can a ceramic hob and built in under oven both be wired into the existing 45A cooker outlet?

Question

I have been told that the built in under oven should be plugged into an ordinary 13A socket and that only the hob should be connected to the old 45A outlet. Is this correct and what electrical standard covers this issue?

Answer 1

this is a common scenario that people come across when altering their kitchen/appliances, i would suggest the best way to go about this is this:-



1. find out the size of cable feeding the 45A cooker outlet, it should be at least 6mm.

2. check the size of the MCB/Fuse supplying it at the consumer unit/Fuse box, if 32A/30A, this can be upgraded to 40A/45A.

3. see if there is a cooker outlet/connection point in the wall in the space where both appliances will be fitted. this is usually lower down, and can be isolated by a switch on the worktop.

4. check the combined rating of the hob and oven in KW, this should not exceed 10.8KW.



if all the above apply, then it's a simple job for an electrician to connect

both appliances to the one supply. all that needs to be done is to install a single unswitched socket next to the cooker outlet fed by a 6mm cable from the outlet plate. then plug the oven in, the fuse in the plug top will protect the oven flex. both appliances can then be isolated from the same switch on the wall.

Answer 3

Fitting A Ceramic Hob

Answer 4

The electrical standard would be BS7671, enforced legally (in a domestic environment) by Part P of the building regs.



Really it's the electrician's call.



I would insist on two circuits for a electric hob and a double oven, as each would justify having 20A circuits

For a Hob & single oven; I'd allow the existing (32A?) circuit to serve.

Answer 5

what is the rating of the oven,what is the rating of the ceramic hob,because these are factors that are relevant to the installation method!perhaps as your name suggests you should get someone who is properley qualified to do this work as this is NOT a job for handymen!!
