Mains supply to garage

[Tricky Dicky]

With work in the garden coming to a close I am looking to start the permane nt wiring of the garage. The main cable will pass from the house through pl astic conduit into the garage the conduit being fixed to a beam above a sid e gate over a 1.2m path separating the garage from the house. Question? Wit h the new rules regarding fire containment within CUs is it permissible to connect PVC conduit and for that matter PVC trunking directly up to the CU or do any particular fixings or glands need to be used?

A PVC conduit installation across the gate to the garage CU could result in build up of condensation that may drip into the garage CU. So either slope the conduit the correct way or fit some sort of drip tray. This could be as easy as a conduit T box with an open bottom (no pun intended) before the garage CU

Other than that I would normally fit a bit of intumescent silicone around any cables entering the CU.

Thank you Adam will do that.

Why not use an armoured cable?

If the cable is doing as he says and connecting _up_ to the CU surely this won't be a problem?

But if it's a metaphorical up - why not a drip loop?

Glands, junction boxes and expensive cable just for a 1.2m run outside. It is much more cost effective to run T&E straight from the house CU.

How can I visually confirm the profile of existing guttering [either half round or deepflow] from 20 feet below?

binoculars, quadcopter or camera on 21' pole?

[Newman]

Thanks

Any particular features of the guttering that would help identify it?

erm, its shape?

That's what I did - the first lot lasted about 30 years and was pliable when I replaced it.

That's what the 3 way conduit box is for. The cable passes through it, is shaped into a drip loop and the bottom entry left open. Then stick a lid on the box.

Either that or drill drain holes if there is a definite lowest point(s).

I am pretty sure the OP can work it out. I just wanted to make sure that he was aware how much condensation could actually accumulate into a couple of metres of conduit. Maybe the conduit box is not needed in the OPs case. But if it is needed it's a £1 solution.

Why would cable need weapons?
