flood light cable

[APE37]

Hi guys.
Just wondering if any one can help on a small job I have, that I will be using as my minor work for upcoming assessment.
Customer wants a flood light over their front door, was going to put a switched fused spur next to a socket in the bedroom run along in trunking for around 2meters, drill through wall and place adaptable box on wall outside then place light and run flex in to box with compression gland. Unfortunately the customer don't want trunking run along inside from the spur. ( all sockets are surface), so was thinking of coming off socket with spur and drill through wall through the back of the spur and run cable on outside to adaptable box. Just wondering if there are any recommendations for cable other than Swa. I was thinking of some black flex clipped to wall, but I think I have read somewhere this is not allowed maybe I have mis read this? just wondering if some one can put my mind at ease and confirm flex would be ok or is there a different type of cable that is not so intrusive like swa.
Thanks for any help.
Cheers

I used MI when I fitted one on my house, stripped bare after it left the wall. You could use conduit or outdoor rubber flex H07RNF.

You could consider the use of this cable; NYY - Protected Cables - https://www.tlc-direct.co.uk/Main_Index/Cable_Index/NYY/index.html

You may also need to consider reg 521.11.201, if the cabling runs above the doorway. Plus it would not look rather nice, I would prefer to conceal the cable in some way, be it inside or outside.

I would go back to the customer to clarify what they will accept!

If you use flex, it will sag over time unless you use loads of clips
If you use Hi-Tuff / NJJ - this will need fewer clips
If you use conduit - it will need fewer supports

Give then the choice!

This looks up to the job with some d line fire clips on approach to the door. Meets all the regs but won't look great, trunking indoors would look better than cabling on exterior walls in my opinion but it's the customers choice.

Conduit on the outside may look better? unsure how far you're running the cable...

Can you not run cable under the floor to avoid internal trunking or outside cable/conduit ?

Why cant you come from upstairs from the light in the hallway?

Are you sure you are ready to undergo an assessment if you need to ask this?

Be more positive man! a valid question was asked.

I keep black fp in 2&3 core flavours along with a few P clips for such exterior lighting clipped cables, a drum tends to last a few years so a long term proposition but is nicer looking/easy so worth it. Many wholesalers might have a titzy if you try to order it though.

What's the issue in using swa? For the size you require it is very neat and durable .

FP200 of any colour is not best suited to external installation due to the sheath not being overly watertight and the hollow construction causing water to be wicked up the cable through capillary action.

The question is certainly valid, for someone of very limited experience and knowledge, not for someone about to undergo an assessment for a competent persons scheme.

what are you saying, the sheath is porous?
