Burying a cable
by Annik • Sat 30 May 2015 17:59

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.

60cm is sufficient for the most part, BUT, where the route of the cable passes under a possible line of motor traffic the depth must be increased to 85cm. The 85cm depth must also be observed under any walkways adjacent to the drive. The dispositif avertisseur de couleur rouge (warning tape) shold be placed 20cm above the protected cable.

That's fantastic, thank you so much. The cable won't go anywhere near a road or public space, it just runs about ten metres from the back of the barn to the greenhouse, underneath the lawn.

We are indebted to you! My husband is a stickler for following the regulations and he couldn't find any.

Annik, an additional remark about wiring. If you want to install a little tableau secondaire in the greenhouse, please respect correct wiring size. How to do it the French way. It is for single-phase and a maximum voltage drop of 2%.

Regards,

Robert
