I live in Canada and was wondering if anyone knows if you have to change the meter base when your upgrading your panel from 100 amp to 125? I have 1/0 aluminum feeds from city with a new 1 1/4 pipe to inside with number 2 copper. I'm just not sure if the city will complain about me leaving the 100 amp meter base or if I'm suppose to switch it to a 200 amp meter base.
The power company is going to confirm that its 1/0 aluminum at the transformer and the meter base, if so I can replace the #3 copper with #2 and upgrade to a 125A in the house. Its an underground service so to trench and replace the wires could be quite costly. I just don't want to leave the old meter base and get pinched for it. But at the same time I don't want a huge monstrosity (200A meter base) for no reason.
