Need help! When we moved in 10 years ago, an electrician "cut" the cable to the lamppost next to the path to our house because the ground nearby was live and the post had been off for a long time. Now we want to install a new post on the same concrete foundation and were thinking of locating the entries to 1) the concrete foundation and 2) the house. Dug pretty deep, 40cm down, around the foundation but can't find anything. Did they run the cable directly underneath into the foundation in the late '60s? I don't even know where to start looking for the entry to the house. Any tips?
