There's more rubbish in this thread than my local landfill.

You've got three options....clip it, hang it or bury it. Its not a nuclear warhead we're discussing.

More like a dirty bomb....... I can smell the advance of the 5th columnists.

Rule of thumb for burying SWAs in the ground appropriate for domestic installations and as recommended by the CITB and in most training manuals is 2 spade depths, just in case you have a propensity for double digging which equates in new money to 600mm.
 
15" will satisfy the utility companies for a gas trench across private land.
But when I've had this problem before, I've just had the client make a little dwarf fence (8' rails on 1' posts) along the route out of 2 x 3 and then cleat the cable to the back of it.
 
I've always got my builders to do trenches, I specify 600mm, then layer of sand, then cable, then sand and fill it. Was a special type of sand but forgotten now.

That's exactly what I have in mind for mine. :)
 
@ritchard Burns, which part of electricians guide to building regs would satisfy this problem? As far as I know this guide would refer to bs7671.
 
Cable laid in silver sand then sharps sand and then back filled with gravel and top soil till 150mm below the surface, then either electrical bricks, not on your life , more like electrical warning black and yellow tape and filled with top soil.
