Burying a cable
We want to run a length of cable carrying a mains electrical supply underground from the barn to our new greenhouse. My OH can find the regulations on the internet for doing this in England but not in France. It will obviously be in all the appropriate ducting etc - but how deep, and at what depth does the warning tape above it go?
We started digging a trench 60cm deep and unearthed all sorts of interesting stones, terre cuite and bits of pottery which we will show to someone knowledgeable when it's all done.
