The local requirement here is Saskatchewan now is for an expansion joint, plus a cable loop box to provide slack if the ground settles. It's ugly as **** but it makes sense. The cable expansion box is below the meter and simply contains a loop of the feeder wires. In the pic, I don't have a generator installed yet. Also, if you are wondering about the foundation, it is the original foundation placed 110 years ago. I'm told that the house originally had a 48 volt battery system with some kind of generator. Electrical service was installed later. When I got the house, it had 80 amp fused mains, and an overhead service drop. I have upgraded it to a 200A service (way overkill - but the panel was the same price as the 100A, just a different main breaker). And I moved the service underground, with the panel for a whole house generator. Oh and the second LB fitting below the cable loop box is an empty conduit for a future detached garage.
