Can i take a Fused Spur from a 45Amp Cooker Point

Spudnik · May 16, 2009

So basically a 2.5 spur from the cooker point would be ok, especially if it was only powering an extractor.

as long as it has upstream overcurrent protection IE a switch fuse

Hi

Yes, I had this debate with one of the inspection councils many years ago and he suggest for this you could even use 1.5mm, but should use larger just incase someone puts a double socket on the spur, this was before part P when incompetent people worked on their own installation ha ha. I believe from the science of it the current will not divert from the direct path to the cb so the load current will not enter the smaller cable.

Please correct me if I have got this wrong.

regards

now i can understand some of you saying the cooker circuit is a dedicated circuit, but like i said in my last post, some cooker switches come with a 13Amp socket outlet on them. so thats not part of the dedicated circuit, because theres nothin to stop some pluggin whatever they like into that outlet. im using just a cooker switch with a fused spur thats going to be rated at something like 5Amps, dnt really see any difference.

and to Electro i always try and use the same size cable to the supply side of the fused spur as from where im spurring from.

You are absolutely correct Dave, however, the circuit should have been designed taking into account the extra loading the socket puts on the design current of the circuit.

looks like youve answered your own question dave

If the circuit is protected by a 32A MCB, how come we are allowed to spur off of a RFC or the MCB with 2.5??

this was my point also

and a fused spur is being used so its better protected still
so the conclusion is yes or no?

looks like its down to personal preference mark. i say no but others say yes

Considering what has been pointed out in the previous posts, i would say yes its fine, especially in this scenario as there is virtually no way anything else will be used on the spur other than the extractor.

i like that jason, "virtually no way"

found this last night, seems our mate trevor linsley thinks its ok to put a 12kw cooker on 2.5 or 4mm t/e

If the correct voltage is used (230) this is nearer 52A.

However, it would still be mad to install a 2.5 cable to a cooker, especially if in the future a different appliance is fitted.

I did see a cooker once supplied by a 1mm cable,
