Trench for cable
Hi we need to put a 16mm armoured voltage cable from. Our house to our detached garage! About 25 meters distance over our Drive . How deep should the trench be as I was told only 300 mm deep would be sufficient by a Solar company!
This sound too shallow so I'm looking for advice.
Expert Trade Answers
"Hi
The depth of the trench should be 500 -600 mm deep. If you can get it more deeper the better it is."

"yes I would say 300mm if you are too worried about it then put it in a metal copex or conduit"
