John,
What happens at a later time if additional loads are added to this service and the calculated load is now at 286 amps? Who cheated who? If I was the owner and requested a 300 amp service I should get a 300 amp service not a 285 amp service. Most of projects I would on I am also the designer so I have the freedom to select the conductor sizes. The cost difference between the 300 and 350 can’t be a very high percentage of the total project. Since you bid the job with 350’s if you decide to use 300’s are you going to reduce your bill for this work accordingly?
