Garden wiring for lights and sockets

[Ventricular Fibrillation]

Its mostly a waste of time doing any cable laying when there's any complexity . Any saving likely be will be wiped out by error

A simple a-b you might get away with it

That's without instruction . Even with instruction it probably won't work out

Exactly. The naïve nature of the OP's questions makes me inclined to suggest getting a professional in and offering to help. Laying a duct with a draw rope in it is a good idea though.

Yes you cab remove the armour.
What you can do is have the armoured cable to into a junction box, with an armoured gland.
The cacble coming out will also need a gland, and this will to to the CU.
The armoured gland will need earthing correctly.

The electrician gave me some glands when he brought the SWA cable. I don't know what are these for but this is something he is going to install later on while replacing the consumer unit. I just wanted to use the opportunity to get SWA into the building when the doors are being replaced. It's the shortest way anyway and no more holes drilled into the walls.

Someone else on a different thread said there should be as few connections as possible so I wanted to avoid that box outside the building for transitioning from armoured to unarmoured cable but now it looks like it is unavoidable.
