fuse rating for electric oven

johnee · 16 Feb 2021

I’m about to change my electric oven. My old oven was just plugged in with a 13a plug into a dedicated 32a supply. The instructions for the new oven according to Curry’s (I haven’t got it yet) say it should be hardwired to a 13a fused spur. My question is can I put a plug on the cable and use the existing socket? Also, in practical terms what is the difference as they are both protected by the same fuse value?

Thanks Johnee

Cookers rated under 3kw can be run on a 13A plug but it may not come with any cable at all if the manufacturer specifies hard wiring.

You need to check the oven's rating and get a copy of the installation instructions from the manufacturer/supplier

IF it says that then - yes.

No difference.

I’m using a double socket as I need one socket for the piezo igniter serving the gas hob positioned on the work surface above the oven. If I have to use a fused spur should I wire from the 32a to a single socket for the piezo, and from there to the fused spur?

Ok.

Yes, but in that case, you already have a socket - so connect the Fused Connector Unit (it's not a spur although that is what people call them; the cable is the spur (fused or not)) to the existing socket wires.

Or just replace the single socket with a double one.

A fused connection unit (FCU) can cool the fuse using far more service area to a plug, and all fuses get hot, that is how they work, however with a socket placed where the ovens cooling fans are blowing past the plug it is very unlikely the plug will over heat, but if where not even in free air there is a high chance of over heating, you can build a double socket box as a FCU and single socket, I did this with mothers house

however as to if it can dissipate the heat any better than a plug not so sure. The system is called a grid switch, the one shown was LAP which I think is screwfix special, so you can have a socket and fuse in same face plate, but as long as in free air or the fan blown air from oven, I would use a good quality plug.
