3.6kw oven on a plug?

[Dave 85]

Hi Lads
The kitchen firm I work for phoned earlier they swapped an oven over expecting to find a dedicated supply but only found a socket. They plugged it in for now but wanna know if that's ok to leave. Putting in a new feed will be a nightmare and I don't wanna get involved. My thinking is that the OSG said its ok to put a 15kw oven on a 32a MCB so surely 3.6kw (max load) on 13a fuse is acceptable if not ideal

well @ 230/240 that would be 15amps I hope they don't want to cook for long periods of time on that plug. No mate I don't think I would be recommending them keeping that oven on a BS 1363 plug

Can you apply diversity here?

 

[malcolmsanford]

Not really Wally .................well not in a court of law anyways....................we use diversity to select a cable and protection device that are suited for each other ...........so if you mess up the most catastrophic event would be it tripping out all the time ................

If you going to load a 13 amp BS 1363 plug top up with 15amps, yes it could work and most likely will work for years, but eventually it will start to deteriorate leading to perhaps dire situations.

No I still think I would be advising changing this

If it has any relevance it's a pyrolitic (self cleaning) oven. I don't know how these work

It works like this:

The oven has special linings, all the gunge comes off with high temperatures.
Very simply, when you select the pyrolytic function your oven temperature will be raised to around 500°C for up to two hours, burning off all food and grease residue and carbonising everything to leave the cavity and oven furniture spotlessly clean. (text stolen from Rangemaster web site)


So, you turn on the oven.
It runs up to high temperature and after a short while the 13A fuse in the plug blows. After two cleaning cycles the plug, or the socket will fail and the kitchen then has no oven until a proper electrician runs a dedicated 16A radial from the fuseboard to the oven.

Yep I agree it needs to go on its own circuit its not a grey area.

Proper job on its own circuit.

Christ that's got to cost a fortune to clean it.
