Advice on trench depth for SWA - Answered!

MikeD

I'm planning to build a timber garden room for use as an amateur radio shack. It will have a TT mains supply from the house consumer unit. I can't attach the SWA to a fence as the boundary belongs to the neighbour so it will have to go underground.

The trench will be about 5 metres long under a gravel walkway and will cross a sewer pipe that is 600mm below the surface with an inspection cover nearby. How deep does the trench need to be?

    Would a glassfibre tube be acceptable as a conduit? It's lighter than a scaffold pole, very strong and doesn't rust.

    If you can't puncture it with a garden fork heavily stomped on, it might suffice.

    I for one am not keen on the likes of scaffold tube, not because of it's mechanical strength but that should there be any relative movement at the end, it could well use it's mechanical strength to shear or certainly damage the cable.
