Folks,
I'd like your opinions on this method of burying cables.
Over here in New Zealand, you are allowed to direct bury Neutral-Screened cable, provided it has an Outer sheath of 3.2mm thickness and it is buried in "fine sand".
This means no de-rating and no further protection.
Once covered over the cable is "there", stuck there as it is.
I was always bought up with this method of laying cables, as an EC.
But one thing the other day made me think otherwise.
Drawing wires or cables has got easier since we used Conduit wires in PVC conduits and we have lubes to help us.
What is your preferred method?.
We have up to 200mm dia conduit and if you can't get a cable through that you've got problems.
It also makes replacement or drawing in new wiring easier.
Take your pick. [Linked Image]
