Electric Towel Rail wiring

[Dom Burgess]

Hi, trying find out if I can run the flex wire from electric towel rail all the into the attic where I would like to put the fused switch spur. (the attic is easily accessible via a door in upstairs bedroom. I would put the switch next to the attic door for easy access). Please see diagram. I'm trying to avoid having to put a connection box in the bathroom under the rail and not having to channel out the plaster etc.

Thanks in advance! Dom

Yes, you can do that, but it might be inconvenient.

Connecting to the lighting circuit might avoid the need for the junction box.

I don't really understand, with the cable as you have drawn it, why having the Fused Connection Unit (the cable is the spur) at a more convenient position would involve any more channelling.

Ah, sorry, I wasn't clear on that front. So, where the cable comes down from the rail, it will run into boxing beneath it. That boxing runs all the way along the skirting and then up the corner of the wall. So, if the cable goes directly into boxing and not into a connection box, then I avoid any channeling or cutting into the plaster. Make sense? Also, it's going into rcd protected mains in the attic, not lighting circuit.

Ok.

So do you think that's ok? Also, do you mind me asking, are you an electrician? Thanks for your responses by the way. Much appreciated.

Yes, it's ok. A retired electrician.

Presumably you will also have to connect the radiator flex to the supply flex within the boxing (if not able to replace the radiator flex) so,

if it will be accessible then any suitable junction box will do but if not accessible then you should use a maintenance free JB.

I like these:

but there are others, of course.

Ah, well that's kind of the question... Can I just run a long length of white round flex all the from the rail to the fused switch in the attic? Wasn't sure if there was any regs about how long a round flex can be or whether I can use that in the attic space. Does that make sense?

 

[EFLImpudence]

Yes, flex is fine.

I can be used just like twin and earth.
