Evening All,
Can an Ontario/Canadian expert tell me any specific requirement for the condition of the service mast that I can use as reference?

A contractor working on a house next door was using a stone slinger to backfill and, what must have been a pretty big rock, hit the 2.5" mast holding our 200A service. The PVC is smashed exposing a 12" x 3" hole. The conductors look fine but I would like to make it crystal clear that this has to be fixed in accordance with code, asap.

Of course neither house is installing the service or even doing electrical at this point so there is no ESA inspection planned. The contractor knows it has happened but I don't want to delay in cases water gets in and then down into the meter below.
Any help or comments welcome.
Andrew
