single core

[tweegs]

I've been asked to wire a shed the customer said that he has got the cable when I looked at the cable it was single core like pme cable I guess the neutral and earth are both in the armoured sheath has anyone used this cable before?

It could be concentric or split concentric. Neither can be directly buried. Concentric you can’t use at all for domestic systems.

If you don’t know what I’m talking about, find an electrician that does.

It could be concentric or split concentric.

Asking as an apprentice, what is the difference between concentric and split concentric?

use armoured cable or high tuff

split con has seperate insulated neutral cores for tn-s
con just has bare outer cores for tn-c-s.

as both types still require rcd protection , they have rather limited use for sub-mains or exterior circuits.

its a split concentric....
go tell `im to get an armoured....

There is a large electrical contracting company in my area that uses split concentric cable for sub - main cable between the DNO's OMB and consumer units when distance is more than 3 mtrs. They have been doing it for years. Easier to install than SWA cable.

it is good stuff to work with , alot lighter and more flexible than swa.

re above comments........I doubt it can be used for any final sub-circuits though?
