I am having a Siemens induction hob fitted to my new kitchen which has a maximum load rating of 7400Kw. From my calculations at a nominal 240v this is approx 30.8 amp.
A 6.0mm T&E has been installed for this hob supplied by a 32 amp RCD.
My question is whether a 32A DP isolator is sufficient or if I should spec a 45A isolator?
The only reason for asking is that MK don't appear to do a 1 gang 45 amp isolator only 2 gang and all the rest of the isolators are 1 gang 20amp switches. I know I could get another make but I prefer to use MK
There is obviously a diversity factor to apply in that its unlikely all heating elements will be on simultaneously but that is possible. The crazy thing is that I am told by the kitchen fitters that these hobs come with a 4mm?? flex fitted and not a direct supply cable connection so it leaves a 4mm flex protected by a 32 amp RCD!!
Am I OK with a 32Amp isolator or should I fit an alternative 1 gang 45 amp DP switch?
Many thanks
Fozzie
