Alternative cable to use instead of armoured when running external power circuit

[Dave OCD]

Surely with M.I. you'd face the same issues with glanding properly as you would with SWA in this scenario ? I'd tell the customer that a short piece of conduit was the only economical solution, however where there is minimal risk of mechanical damage I've seen a lot of T&E externally clipped with no apparent ill effects, not for many years anyway. Just saying....

Is there not a conventional route internally?? I can't even remember the last time I even contemplated doing something like you are suggesting in a house?

I'll throw Pyro into the mix.

So would I. Slim, unobtrusive, impact resistant, UV resistant etc. If 2.5 T+E was adequate for the circuit then 2L1.5 MI will probably be suitable, only 7mm diameter including PVC oversheath. It can be glanded within the depth of the wall, into a coupler bushed into a rear knockout of a flush metal socket box. Using an earth-tail seal overcomes the need to access the gland nut to prove maintainability of the CPC connection. No-brainer in my book.

Hi guys, update: i went to 3 wholesalers intending to get myself some Hi tuff/NYY-J and all i got from all three suppliers was a blank stare and that they would have to order it in specially, ended up using t+e in conduit as the customer wanted it done ASAP... at least next time i know to order in advance.

NYY - Protected Cables - https://www.tlc-direct.co.uk/Main_Index/Cable_Index/NYY/index.html

www.electric-cable.com - NYY-J Cable - https://www.electriccable.co.uk/nyy-j-cable.php

Both do cut lengths.

I agree but the problem is the cost, it's only oddballs like you and I who have stocks and offcuts of this stuff on the shelf and buying it new is just ridiculous now.
Plus I don't do general domestic work like this, and I assume you probably don't do too much of it either.

Yeah most wholesalers I go in don't stock it, and they usually try to sell me SY control cable instead....always have a bit of 2.5 and 1.5 NYY in my lock up now, and order more from TLC when I am running low.
