3.6kw oven on a 13amp plug top.

[markthespark]

Hello i have been asked to install an oven that is 3.6kw, i am wondering whether this would be fine plugged into a socket behind the existing oven taking into account diversity.

or whether i need to put it on its own radial supply.

Is there anyway of fusing a ring main down to 16amps?

Thanks.

Well I can tell you now I have a 3.6kw cooker on a plug top in my house, it has worked flawlessly for years. Please don't listen to my advice though.

What do the Manufacturers Instructions tell you??

Aye but you're not telling him about the bit of 5mm bolt in the fuseholder are you??

The manufacturers instructions will likely require a 16A connection. I've been called to two of these this month - it seems that that a lot of the new ovens require a larger supply than the old ones.

Well I would do what is recommended in the manual to be honest, even if allowing for diversity it will be okay lol

Yep agree best put it on it's own radial

own radial 20a dp switch

I have noticed most ovens that used to come already fitted with a 13Amp plug,now just have terminals for you to connect your own cable and I think there is a clue there (manufacturers are aware that a 3.6kw oven may work fine on a 13Amp plug ...for a while.) . When you go to cook Christmas dinner and the oven is working at full capacity for long hours then i would consider diversity to be a bit of a red herring mainly used by lazy and/or incompetent fitters, to avoid installing a new 20Amp radial,so they just throw it in a socket designed for 13 Amps max despite the appliance being capable of pulling 14 amps..!
A 3.6kw cooker needs a 4mm hofr (heatproof) cable from cooker to 20Amp isolation point,then feed isolation point in 4mm pvc twin + earth and protect circuit with 20Amp ocpd.

Have you ever seen what a 2kw heater can do to a plug top? Putting a modern oven on a plug is what you call sailing close to the wind

No I haven't what happens?

I was taught always use a f.c.u for an oven, as the plug top will heat up.

 

[Pete999]

It's only a thought but 7671 RECOMENDS that any fixed load over 2KW ought to be on it's own circuit

 

[Guest77]

And I agree with them Pete, still interested to know what happens when 8 amps is connected to a 13 amp plug top though :biggrin:

Depends on the size of the amps.

If it's those really big amps you're in trouble.

 

[Guest77]

is 8 amps big connected to a 13 amp plug top?

 

[Pete999]

Not if it's a big plugtop

 

[LeeH]

Like this?

---- job chasing that socket in though....

That will do

If the plug has got a 3 Amp fuse in it,then yes ,8 Amps is big.
I think you are avoiding the not insignificant point that it is not good practice to try to protect equipment with a potential operating current of 14 Amps on a 13 Amp plug. No amount of lateral thinking or outright belligerence will change the fact. 14 Amps with 13 Amp protection = No.
