Hi guys. We are renovating our kitchen and I could really do with advice on wiring oven/hob. There is a designated oven circuit with two 2.5mm2 twin and earth wires - one going to the oven and another one to the ceramic hob. The oven is rated at 0.93kw/cycle and the instructions say that minimum 2.5mm2 cable is required. The instruction for the ceramic hob do not specify the cable required but the supply is stated as "220-240V ~50Hz 5.04kW - 6.4kW". Could you please tell me if 2.5mm2 cables are enough for the above appliances? Thanks in advance.
The 2.5mm2 presumably heat resistant flex to ceramic hob is interesting tbqh - I wonder what answers will transpire.
Both cables are 2.5mm2 twin & earth - one is behind a built-in oven and another one under the floor boards going to the hob in the kitchen island.
Manufacturers cable stipulations are not being adhered to Wendy tbqh.,manufacturers stipulations override 7671 in some instances. The two 2.5 cables presumably emanate from cooker fo plate/s with say 4/6mm dedicated to fo/s backed with a 30 amper and fed with with a 30ma device? Maybe the adriatic equation covers the 2.5mm heat resistant flex cpc?
Thanks for your replies guys. Would we need to replace it with 6mm2 or 10mm2? Also, is 2.5mm still good for the oven?
I would use 4mm heat resitant flex for the hob Wendy - however being diy I think its best for a sparks to answer. The oven needs a tad more info to be put forth tbqh before a definative cable size can be chosen.
I don't know Mr R. Any chance of telling Wendy what exactly she needs for the cooker /hob - in my gaff stuff like that is no problem, but as I am not a sparks its best that one of you qualified chaps answers the ladies question. Thanks Mr R.
Yes, the oven is Electrolux EOC5440AOX and the hob is Stoves SEH900CTC. I just spoke to the Stoves customer service and their engineers recommended 6mm cable – the problem is though - the compartment in the hob for the wires is quite small – I doubt the 6mm cable will even go through the first opening. I mentioned it to them but they had no solution whatsoever except essentially saying “get an electrician and let it be his problem”. P.s. – don’t know why I am being called Wendy – it’s Jenny
Also, not sure of the relevance but feel like I should mention - we put the hob on full power (all four rings) and left it for 10 minutes and while the cable did get warm it wasn't hot.
''and another one under the floor boards going to the hob in the kitchen island'' Hi Wendy. With ref to the above - where does the above cable come from? The way I read it is is that you have a 2.5mm T + E cable coming out of a cooker outlet plate and then running under the floorboards to the island which has another cooker outlet plate, and from this plate another length of 2.5 T +E goes to the hob? The whole thing is totally unsuitable if this is the case tbqh, and a revamp would be required.
There is one cooker outlet with two 2.5mm T&E cables coming out of it - one going to the oven and another one going to the hob in the island (under floor boards).
What size cable feeds the cooker outlet? I suspect its 4mm which is ok but then again it might be 6mm? and what size breaker in the consumer unit feeds this dedicated circuit?
I am not sure but I think the outlet is being fed with 6mm (maybe even 10mm )cable. I have attached the photo of the breaker and there's also a 45amp switch.
