Induction hob butyl cable size

[Asinrute]

I am installing an induction hob to a dedicated 32a supply. The hob is rated at 20a. From the hob I am going to use a heat resistant butyl 3 core cable. The 2.5mm cable is rated at 24a, this seems a bit light to me, do you think I should use 4mm which is rated at 35a or will the 2.5mm be ok, Thanks in advance

To be honest if the induction hob is rated at 20a I expect a 2.5mm will do but you could install a 4mm to be safe. what do others think?

read the manufactures booklet.

Manufacturers booklet doesn’t specify the size to use just says must be suitable and heat resistant

2.5mm is fine.

The other thing to remember is the average current during operation will be "half" the max draw once it's up to temp.
