Which wiring/cabling?

[pinheadplanet]

Hi

Was just about to buy 1.5mm twin & earth cable, which is oval, to wire up an external light but now notice the light specifies 6mm round cabling. I can't see round twin & earth anywhere, which cable should I buy? Screwfix, wickes etc. anywhere in southampton. Only need 4 metres!

is this right, or too thick at 2.5mm?

Thanks

Twin and earth is the flat cable used in internal wiring. That is not the type you need.
You need a round, flexible 3-core cable with an overall diameter of 6mm.
Don’t get confused, the 1.5mm you refer to is actually 1.5mm² - this refers to the cross sectional area of one of the live conductors.

The Wickes cables is huge. You need something like this

If you don’t need 50metres then Sfx do this:

'Round twin and earth' is called 3 core flexible cable.

The measurement of 6mm. diameter is purely to ensure a water-tight fitting and nothing to do with the wire size, whether 1, 1.5 or 2.5 square millimetres .

Yeah I know about the conductor size, how about this cable I just found at screwfix, would this be ok?

Yes, it says the diameter is 8.1mm.

8.1mm is TOO BIG.

The instructions say 6mm.

8.1 is bigger than 6mm

I just told you the cable to buy from Screwfix,!!!!

Didnt you like the colour??

Actually went for the 1.5mm as opposed to the 0.75mm, but yeah I hadn't read your post in it's entirety obviously Guessing I'm ok with 1.5mm right? And yes I found the black instead of blue!

It says 6mm. 'minimum' and 'at least'.

Ahh yes didn’t look at the picture. Apologies!!
but it’s a stuffing gland and they aren’t universal for all cables. Should be ok for 8mmish though.
