Good afternoon:
As Reno said, there may be other issues with this.
Keep in mind that Reno and I are 'stateside', and use the NEC, and out area POCO rules. One of our Canadian members should jump in on this.
The service in the pic would be 'red tagged' IMHO, by me, as to why are the conductors wrapped?? Are they damaged from rubbing on the corner of the structure?
The mast/riser is considered 'inside the structure'. This may be the result of an addition to the structure, which enclosed the riser. Possibly this was an 'open' area between the two buildings?
