I've just installed an electric shower. The 6mm T&E cable runs from the
loft down through an unheated airing cupboard. Does the cable have to be
inside trunking or conduit where it runs through the airing cupboard, or
can I simply staple it to the back of the cupboard's door frame, using
cable clips like this: http://tinyurl.com/nllh2b2

Many thanks for any clarification..

In general, no, it does not need to be in trunking.

Doing so will mean the cable will get a slightly lower rating compared
to being in free air (clipped-direct method).

However, if you have a reason to suspect the cable will get clouted by
hard things in normal use of the cupboard, then it should be protected
(installation appropriate to the environment). It's not a hard and fast
rule, you will need to assess it.

Cables are normally surface mounted and clipped in airing cupboards, if
you want a "how's it normally done" baseline

Clipped direct to a surface is fine unless in an area where its likely
to be subject to mechanical damage.

Many thanks, Tim and John! That's what I expected, but thought I'd better
check!

I agree with what Tim and John said.

But is the correct name for an unheated airing cupboard just "cupboard"?

Also, make sure you route it such that no clothes, towels, or other
fabrics can be piled in contact with it. The cable needs to be
ventilated.

May need to derate for higher ambient temperature (I assume 40C would be
a safe ceiling for an airing cupboard).

In my case it is a cupboard with a doorway but no actual door. So the
slatted shelves are open to the air on landing, apart from a curtain which
I draw accross if a guest is in the house!

Good point - thanks.

Please may I ask, what power rating is the shower?

I was thinking of installing an electric shower as a back-up to the
aging combi boiler. I thought that 10.5kW was the most powerful
electric shower, so I went to TLC's calculator and typed in 11kW and
12 metres of cable, clipped direct. The calculators aid 6mm^2 would be
fine; I was expecting to have to run 10mm^2 cable.

Sorry to hijack the post. It's too late for the OP as he has already
installed 6mm^2 but for everyone else, should you use 6mm^2 or 10mm^2
cable for showers?

Thanks,
Stephen.

Yes.





Oh, more detail?

;-)

It depends on the circumstances; primarily the rating of the shower, and
the length and nature of the cable route.

This gives you the full explanation:

My local council powered its street lamps with 'clipped direct' to a
barbed wire fence for a 'temporary' 5 months using what looked like 4mm
T&E .......... thought it a bit mad, as in event of fault the very long
fence would become live.
