Hi,

We are currently having our kitchen put in with a built in electric oven. The power consumption stated in the the oven literature is 3.6KW yet our builder keeps insisting that a 13A switched fuse spur socket should be fine.

I have tried explaining to him that with a 13A fuse the maximum power it can handle is 3120W.

He says that he has installed many electric (Fan assisted) ovens and even bigger ones than ours and he always uses a 13A switched fuse spur socket?

Surely from the basic formula, P = I * V the required fuse for the oven would be around 15A or am I missing something here?
