I am about to resurface a driveway between the house and an outbuilding. I anticipate wishing to run mains electricity to the outbuilding on the other side of the driveway at some future time (but not yet!).
It would seem sensible to lay some sort of duct beneath the driveway at this time. What are regulations? depth? best practice? As the cable will be armored anyway can I just use a length of 4" sewer or even 2" plumbing pipe as a duct? Or are there special requirements for electrical ducts? Identification? Color coding? etc.
Am I likely to run into trouble getting sparky to certify when eventually comes to laying the SWA cable?
