I've to dig a couple of trenches for swa supplies to a garage and workshop. Would you suggest I lay a tape in there whilst I'm at it? Anything special about terminating the tape? (I've never seen it, let alone installed it!)
As JP says, depends on soil conditions. The electrodes need to be at least 600 mm deep because of frost (BS 7430) ... the SWA is recommended to be at least 500 mm (although Sections 705, 708, 740 etc. require at least 600 mm in general, with Section 705 further requires > 1000 mm in cultivated ground and I would recommend keeping to this for the electrodes also).
