Armoured Cable Thickness?

There are special requirements for electricity in buildings with livestock. You really need an electrical engineer with agricultural experience to design and spec the installation.

with all due respect, a qualified electrican will be more than adequate to spec this in my opinion.

Horses are particularly susceptible to electrocution. If you don't have the knowledge to do the work and don't have the equipment to test it then get an electrician in.

Read BS7671, section 705 in regard to Agricultural and Horticultural premises, this should help you with what you propose to do.

Good point, although I doubt many electricians are au fait with horse physiology.

The problem for horses and other 4 legged mammals [cows are also prone to electrocution] is that being 4 legged, their leg base, to coin a term is significantly larger than that of a human - so if they are standing near an earth fault, the potential gradient in the ground puts more than 40V across their legs.

The Newbury incident was a bit extreme and I suspect that it was a high voltage cable causing the problem. Having said that, the distance of the stables from the main incoming supply does pose some issues which means that some thought is needed for the earthing and bonding of this installation.

No one mentioned Part P as an outdoor lighting or power installation?

60m of 6mm² PVC insulated SWA will withstand a continuous load of 6KW in the configuration you describe.
You will only need 2 core as the armour is the earth conductor.

Watch out because there are a few 2 core SWA sizes where the armour isn't low enough impedance to act as earth

OP's in Scotland.

There is no mention of it being a dwelling with residence by the OP which it what Part P applies too

Still think it should be TT.
