My son has purchased a property and the oven/hob/hood are not connected to any service at all (we cant understand why)
We see that the hob is gas, the oven is integrated with the hob. The hood is also above but not attached to anything. My question is this
Given the hob is gas, can I supply the oven from the back of the dual 13amp socket thus leaving that socket free. Can I also feed the hood extract from the same socket looping the igniter from the hood extract? In other words supplying all three from the socket but ALL having their own switched flex outlet spurs for isolation purposes? Im not sure of the best way to do this.
To help the oven is a Beko 2.3KW the extract has a small fan motor and the ignitor is milliamps (I assume)
Am i pushing too much onto the dual socket? I can also state that looking at the fuse/consumer unit that the washing machine already has it own separate socket designated, the only other socket in in the kitchen is the one which I was looking to supply the oven/ignitor/hood!! Is it too much too ask?? advice very much appreciated, a separate cooker circuit is not there and it would mean floors up and carpets up which he does not want to do!!!!
I am a retired ex maintenance electrician who is not up on domestic regulations , I spent 30 years on maintenance in factorys but I am not fully conversant with domestic regulations, its whether I can do the above with fused spurs is what I am asking?
Again your answer is rather insulting, especially to a person who has probably more experience than yourself, all I am doing is requesting advice, I have seen ovens with plug tops on quite legitimately used check cookology ovens, some of theirs are up to 2.4kw with plug tops already fitted! stating they can be plugged in!! your advice is conflicting.
Are you a tradesperson and able to answer this question?
In short No, you cannot run all three from the same socket
If you have a final ring circuit this will have 32 amps in the circuit as a maximum.
The oven needs a 13 amp fused spur, ideally a dedicated radial, so as not to overload the circuit and risk damaging the cable.
The cooker hood needs a fused spur with a 3 amp fuse in it, the gas ignition also a fused spur with a 3 amp fuse in it.
You really should get an electrician in to do the work who is up to speed with the current regulations. They can adapt the circuit, test it and issue you with a certificate. Most ovens of the type you have stated clearly state not to fit a plug.
Hope this gives you some clarity.
The oven is never going to overload or damage the cable. 2.4kW is around 10amps, and let's bear in mind that the element is only pulling full load for fairly short periods of time. As a test you could plug it in, put it on full blast then stick a clamp meter on the flex while it's preheating and after it's up to temp.
Personally I think 3A fuses in a plug each for the ignition and the extractor would be fine. The ignition current is negligible and the fan is probably 150W max, so less than an amp.
Fitting SFCUs in a kitchen is classed as minor work IIRC, but fitting a plug on an appliance and plugging it in is irrelevant to Part P.
Sounds like you should have a grasp of what is electrically safe or not, so trust your instincts I'd say. The only caveat is whether the circuit is up to scratch and only proper testing will tell you that.
Appendix 15 of BS7671 referring to ring final circuits states that, “The load current of the circuit should be unlikely to exceed for long periods current-carrying capacity of the cable. This can be achieved by: (iii) connecting cookers, ovens and hobs with a rated power exceeding 2KW on their own dedicated radial circuit”.
As your oven is rated 2.3KW my professional interpretation is that it should ideally be supplied via its own dedicated circuit and you should avoid connecting it via a plug or spur from a ring circuit.
Please do try not to be offended by the limited time of my extremely accurate experience and hard earned expertise, but I must agree unless you’re a Part P electrician it may be best to hire one.
P.S. to those who gave different advice page 505 of the big blue book.
