Power & fuse rating

Hi,

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

I have tried explaining to him that with a 13A fuse the maximum powe it can handle is

Actually it's worse than that as nominal voltage is now 230V so that gives a current of 15.7A. What I would do is to install a seperate radial circuit for this using a 20A breaker on 2.5mm cable via a cooker outlet. This would comply with regs. Your builder is not complying with regs and diversity only applies with a cooker and not just an oven. Is your builder part P (building regs) registered? Has he done any kind of testing of the circuit he intends to add your oven onto? If he's done this with bigger ovens he's going to have a lot of disgruntled customers wondering why the fuse keeps blowing or the breaker keeps tripping whenever they put the kettle on while the oven is on. Still these guys keep us sparkies in business fixing their bodges.

  • All these things (appliances, cookers, fuses, breakers) have a fair tolerance. The mains voltage can be a few percent out too. Though fuses and breakers will carry their rated load continuously and probably a bit more.
  • There may not be a regulation saying you can't but what if the cooker's manual did say that it must be on its own circuit, the cooker were to burst into flames one day and burn your house down (because of a fault rather than the way you wired it) and the insurance company found out.

If it is suitable for effectively running off a 13 amp supply it will come with a fitted 13 amp lead and plug.

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.
