Hob / Cooker Cable

[Jimmyb]

Hello all, can someone tell me what the best cable is for connecting hobs and ovens i thought heat flex but now I'm being told sparky ive been working with today that t&e is fine

I also wondered if connecting the 2-kW oven straight into the the cooker switch not fused apart from 32amp mcb is ok as i was thinking it would need fusing down to a max of 20amp due to it load

I only been in the industry for 3 years and he has been init for 30 years so i just agreed with him but i cant see how he is right.
Have i been doing something the hard way by using heat flex and end up putting in a hob isolator and a fcu for the cooker

Many thanks

Jimmy

put a socket on the isolator then plug oven in then it s rated at 13A

I have always used T&E from the cooker outlet to the oven,hob usually has flex attached and straight into another cooker outlet,both controlled from double pole switches.

can you go into that a bit more (what fuse ,cable sizes what u join them with)

 

[adam.h]

just out of interest, if you had a seperate electric oven with a gas cooker, could you have them both off the same cooker switch?

Could be wrong but i seem to remember that if the oven is built in then T&E is fine. if it is free standing them 10mm flex should be used

10mm flex? Do you know where i could buy some?

LOL sorry guys, thats what happens when im typing posts while on the phone. Do appologise. 6mm flex is what i was getting at

I tend to run the cooker switch on to a 20 amp mcb,you could even use a 16 amp,in 4mm cable.
Then to a double socket,for ign hob,and the cooker on a 13 amp fuse.
All cookers should have a max demand in kw on them.Then do your sums.

Must admit i ALWAYS run the cooker circuit in 10mm and sometimes 6.

Even if its a 13A single.

 

[High Tower]

10mm T&E to the connection point, and then 6mm flex from there

 

[billybob]

yep,thats fair enough,you don't know what size of oven is coming,I suppose.
In terms of that situation though....

why 4mm if 20 or 16amp

 

[billybob]

For the simple reason that whenever I run a radial,be it sockets or whatever,(although not lighting)I run it in 4mm,so have it handy,plus the 4mm will take on extra load.unless theload exceeds the 4mm cable safe capacity.
