Is 4mm heat resistant cable okay for 7.5kw range cooker?

[chris140]

The electrician that installed my cooker circuit put in 10mm cable with a 32a fuse, a 45a cooker switch and 10mm cable to the backplate for behind the cooker. He put this size in as I didn't know what size cooker I was going to be getting.

I ended up getting a 7.4kw range cooker and the electrician has connected it with 4mm heat resistant cable instead from the cooker to the back plate, instead of 6mm. Is this okay, and is it okay with the 10mm cable and 32a fuse?

Thanks

7200 / 230v is just under 32A, and 4mm is well capable of carrying 32A.

The cooker will never, in practice, pull the full 7200

Take care

At least he used heat-resistant cable, most just use twin and earth.

quite right, allowing for diversity I doubt it will pull 20 amps.

Nothing wrong with T&E for the final connection to a cooker, This is fully compliant with BS7671
