Range Cooker Isolation Ask questions and find answers to many subjects relating to electrics and electrical work

[Beaconhill]

I have a induction range cooker which draws 17.5kW when everything is switched on. I know my existing 6mm supply cabling needs to be changed to 10mm but I am having problems in sourcing a double pole isolator switch. The maximum I can find is 45A. Any help with specifying the isolator and consumer unit switches would be great.

You have 17.5kw full load.
This would calculate at 76.1A.
We can offer diversity, making assumption of the likelyhood that the cooker will not be at full load.
Which would give me 33A if isolator was without a socket-outlet attached and 38A if it did. This would allow a 45A isolator to be used.
