Cooker/hob connection at outlet.

[Albirto123]

Just getting back into the trade after a brake of some 5 yrs because of circumstances: Can I ask Is it still permiseable to connect both a hob and oven (usually manufacturers different size cables) into one outlet plate behind the oven?
Or is there a better solution now as it always seemed to contravene good practice to me?
Also can the isolator be local in a cupboard instead of above the work surface where room for isolator is limited/tricky! The outlet we be literally 2 meters from consumer unit clipped direct to stone wall covered one one side (with 1 cm gap) by insulated plasterboard!
Also I found 10mm was always a pain to use but told lately that even Wickes kitchen fitters require 10mm minimum for all combinations of hob/oven sizes! Was 6mm really so bad!

Kitchen fitters are not a good source of education for electrical work in general.
Check the manufacturers instructions.

Click scolmore do a dual appliance outlet plate that is a neat solution to this. FWIW I personally think the standard outlet plate terminals are okay with more than one appliance terminated into them, as long as the terminals are not overfilled.

Isolator fine in a cupboard IMO, though there are differing opinions on this.

There's nothing wrong with 6mm, or whatever cable the circuit design indicates, or at least there shouldn't be. Problem is, there are some manufacturers (Aga, Rangemaster to name a couple) that specify a 10mm circuit for some of their cookers. Ridiculous, as near impossible to connect the appliance to the outlet with 10mm.

Yes my kinda thoughts also. I like the sound of a duel connection plate though and will check it out thanks.

Terminal box on a UK cooker from 50 years ago would easily accomodate a 10mm2 cable, even though 6mm 2 was adequate.
Nowadays, most cookers, ovens and hobs are originally designed for three phase supplies, even though that's rare in domestic UK, but that's progress, I suppose.
It's often easier to use a 5 core flex of reduced cross section than to use a 3 core to carry the whole current. The lives and neutrals can then be paralleled up at the wall connector, which generally will have more room and larger terminals.
