Shower Cable Surface Mounted

[gazdkw82]

I was at my folks house yesterday and when I went to the toilet I noticed whoever has installed the electric shower (it's been there a good 10 years) fed the cable down the wall in trunking. The shower is slightly offset to the bath so I guess it would sit on the outside of the shower curtain but it still didn't look very good.

It had me thinking, say you had a shower to install and couldn't sink cable behind tiles or into the wall etc, would surface mounted options still be viable?

512.2.1 "Equipment shall be of a design appropriate to the situation in which it is to be used or its mode of instllation shall take account of the conditions likely to be encountered."

134.1.1 "Good workmanship by skilled or instructed persons and proper materials shall be used in the erection of the electrical installation."

So in practice, you'd have to come up with a wiring system that is suitable for the external influences, probably AD5 (ref appendix 5).

I reckon surface mounted trunking would be about a P120 or P80 in terms of roughness...

P120 p80?

I'm confused, what's the grade of sandpaper got to do with trunking??

It's like a scale. If someone suggests a way of doing something, or shows you a picture, you take a view on how professional it looks or will do the job. For things at the lower end of the scale, you could describe it in terms of roughness. There is an established method of different grades of sandpaper in terms of how rough they are. P80 is pretty rough.

Rough may not necessarily be dangerous or non-compliant with the regs.

Apologies for the confusion.

New to me but makes sense
