I'm with Hotline. I've never seen a 150 amp meter can. Actually, there is no such thing as a 200 amp panel. They are 225 amp rated bus with a 200 amp main. Heck, if you're worried about it, ask him to pull the 200 amp main out, and install a 150. By doing that, you open up other issues concerning how much load is on the house, etc. Though, I would be hard pressed to believe that a house that has an existing 60 amp service wouldn't run off of a 150 amp main, but I'm not the electrician on the job.
The person to ask, is the inspector (Authority Having Jurisdiction). Let him give you the "official" position.
