Does a 4.8KW cooker need to be on its own spur

Anonymous user 09/03/2024 - 2.40 PM

Our old cooker was rated at 3KW with a gas hob and it just had a standard 13 amp socket which plugged into the wall near the cooker. The electrical part of the cooker died a few months back and my landlord has finally bought a new one however he has bought a double oven with a gas hob with a draw according to the manual of 4.50 - 4.8KW. I had assumed it was a cooker radial circuit the old cooker plugged into but it turns out it is actually just on the downstairs ring main. My landlord now wants to change the current double 13amp to a 45 amp cooker switch with a 13amp plug socket next to while keeping it on the ring main. I have explained that this is not a good idea and that he needs to get a qualified electrician to install a new radial spur from the fuse box to the kitchen, it is only 6ft between them. However he does not want to do this because currently the house has a very old fuse box that uses fuse wire so my understanding is that it would need to be upgraded to a modern consumer unit to install a new spur. Is it a legal requirement for a cooker to be on its own spur because I think only that will get him to do it? If he does this will a 2.5mm cable be ok to connect the cooker to the new switch? Thanks for your help

Not good practice but will suffice with a 20A breaker as 4.2kw=20.8A and using diversity load comes in at approx 13A(+5A if socket inc in control switch) so well within technical limits. A new radial circuit would be required to have RCD protection and be notified to building control. Really aught to run a 6mm supply using a registered spark who could do the registering for you with the minimum fuss.

Yes agree with above this is something for a qualified spark & needs to be notified. This isn't something that should be attempted by yourself or Landlord. Needs new circuit new consumer unit & wouldn't mind betting that your Gas & Water supplies need bonding too as you say it's a really old consumer unit etc

This should be on a dedicated cooker circuit using a 6mm cable not on ring circuit
