Reusing Electrical Cables
I’m building on a site that had a manufactured home some 20 years ago. The pedestal for the electrical service is still there and powering my tools and the well pump. Also left in place are the three main cables that used to power the manufactured home, which was farther from the pedestal than the house I’m building. In the attached photos, you can see the big cables exiting the pedestal through a conduit that’s covered by a rusty steel box on the outside. My plan is to pull the ends of the cables out of the pedestal so that they extend out of the top of the conduit on the outside and then try to pull the whole cables out of the conduit so that I can use them to power the new house and save a lot of money and materials. I know I’ll need an antioxidant compound to join the aluminum to my copper service panel inside the house. The other end of the conduit is buried somewhere that I haven’t found. Would it be better to try to pull all three cables at once, which is my inclination, or one at a time, and do you have any other suggestions?
If the buried ends of the cables are too bent or attached to something, they may not pull through, in which case I’ll have to find them. They’re probably around two feet deep. My understanding is that even the better metal detectors can’t find anything that deep. Is there another way to find the ends without digging a lot of holes and hoping to hit the right spot?
