kitchen cooker and hob HELP PLEASE

[rayb67]

hi all, i have decided to replace my old gas cooker with electric cooker and hob, my quirey is this,
the new cooker is 2.500 kw max load and the hob is 6,0kw there is one single 6mm cable that runs from a 32mcb to a 45amp double pole switch then the 6mm carries on to a cooker control unit,
the cooker instructions say to hardwire it to a 13amp socket outlet .
is it possible to wire both i.e cooker and hob to the control unit using both 2.5m cable for the cooker and 6mm cable for the hob and do i have to notify under the new regs of fitting the cooker,
also would the 6mm cable be ok or would i need to replace it with 10mm. any help or advice would be fantastic...

Using diversity, you can fit these appliances to the existing circuit. However, you must use the same sized cable throughout, unless you fuse it down.

Assuming the cable run is not excessive for the load:

Use an MK 1133 BRO to join the 6mm² cable from the iso switch to the two 6mm² feeds to the hob & oven, then put a socket on the end of the oven feed. Has the oven a ready-fitte lead?

Make sure also that both of the appliances are within 2m of the switch, which should be easy to access in an emergency.

Finally, this is notifiable.

Re-read part of your post:

The cooker control unit & the DP switch? Where are they in relation to the appliances?

Ideally, you need the apliances within 2m of the DP switch. Ditch the CCU.

If you want to use the existing cable, ditch the CCU.

Take a switched feed from the DP switch to the JB, making sure it is accessible (behind the plinth for eg).

Then run two feeds as suggested. The oven will plug in to the socket you fit, the hob you hard-wire directly to the 6mm² you have taken from the JB. Make sure also you can access the plug top if the need arises (to change the fuse).
