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?

Physically one can run that on a 13A plug, we used to have 15A loads on
13A plugs, but it should not be done, and you as a customer have a
right to expect a legal compliant installation, and to insist on such.
Also some makes of plug wont handle that current, and will end up
melting down.

Given his response I'd be keeping a good eye on the whole proceedings.

Physically maybe but it would be a breach of 3:6:2 to allow a current
greater than the that which the circuit is designed to carry.
