How to actually TT a shed/garage?

You can purchase plastic glands for SWA to isolate the earthed armour from the shed.

Do you have a link? When I search for plastic swa gland I just get stuffing glands.

I see no reason not to use a stuffing gland as long as the cable is properly secured by cleats etc.
A bit of heat shrink over the end of the cut end of the armour will keep it neat, just remember not to shrink it until after the Zs test

I'm going to extend the example now!!

If the shed/garage is going to have sockets/lights AND an electric vehicle charging point would you need to take 2 separate supplies (i.e 2 x 2 core SWA) as the charging point needs to be on it's own dedicated circuit? Or could it be on it's own dedicated circuit from the Garage CU? I would have thought the former as otherwise it's not really a dedicated circuit.

Apologies if this has been covered but If supplying a ev point I think youll need something like 40a (min depending on size of charging point) with no diversity allowed? (not done the course but im sure thats right) so in a normal house you'd probably split the tails into a new small board purely for the ev. Based on that if you were powering a shed that subsequently supplied an ev you might have to take that into account? If just a shed then its unlikely youll be using that much power at one time but might be worth considering??

Never again am I going to spend hours with TT rods attempting to get a good Ze, another couple of easy year’s fitting meters and I’m done working.
