NYMJ or SWA?

[Dr_Doolittle]

i'm running a cable from the CU to a shed for a twin socket and a light. The cable will go out and along the side wall of the house, then along the back wall of the house and along the diving wall in the back garden, and into the shed which is alongside the dividng wall. The cable will be about 8 inches from the ground, clipped to the wall, and 100% visible.

Is it ok to use NYMJ, or should i use SWA?

Thanks.

NYMJ?

SWA, NYMJ doesn't have mechanical protection.
Hadn't heard of it myself but a quick google seach shows it as a flexible cable.

Sorry, maybe it's an Irish thing! NYMJ is resistant to deterioration from sunlight and wet conditions. Doesn't have mechanical protecion like SWA though.

NYMJ is used alot over here. i.e you would use it for an outside light mounted on the wall of your house. What cable would you normally use for that? (just out of interest, nothing to do with my original query)

Black flex

I used 1.5mm 3 core on this project it seemed the most durable on offer at B&Q. Looks ok IMO. I am planning improvements this year, btw.

Sorry Steve but that looks awful.
Personally I would sooner destroy the decorating inside a little and have no cables on show at all. Maybe it's just my pet hate but I HATE cables on show outside a house. I even ran (internally of course!) two CT100 cables prior to a visit by Sky for fear of them putting a cable on the outside of my house.
If I had no choice at all then I would prefer unsheathed pyro.

Ah a man after my own heart.

I love pyro

Indeed, but on a DIY level of budget and skill, black flex and plastic glands is a more practical option. And I know it looks terrible. The re-hash will involve all cable running higher up. The cable that runs lower goes off to a 500W floodlight mounted on a mast fixed to a fence (i know, i know), the fence will soon be extended which will enable me to re-route this. I used two lights so the whole garden was lit evenly. It works really well.

Some fair comments Steve.

Never a good idea to take cable through the top (2nd picture).
With the best will in the world, moisture will eventually penetrate.

Drainage hole in the bottom. I'll not show you inside, it looks terrible. I'll show the after pictures soon.

Looks ok IMO.

Wish I could change the mind of my missus that quickly

There's no need - it's far easier for her to change yours.

You may have a point there......
