Does anyone (besides me) install 150 Amp services? On a small home with gas appliances and a 60 Amp service, which needs an upgrade for central air, the load calculations still fall shy of even the minimum 100 amp mandated by code. I won't install only 100, but 200 seems excessive for such small homes. Some people feel that the materials dont cost much more for 200 than 150, so install 200. Others feel differently. Anyone?
Some people will never use the capacity of a 200A service and do not want the extra cost, I've noticed that too. I would give them the option. Most times it's not much difference from 150 to 200 though. If there happens to be a long or difficult run to the water main and there is a #6 copper in place already it wouldn't have to be replaced for a 150A service. Put that together with a long SEU run and it could mean a significant difference in price.

In my area we have only one supply house in the county and they handle ITE loadcenters. A 200A 30-40 ct. copper buss indoor loadcenter runs $147.00. A 150A loadcenter runs $180.00. A 100A 30 ct. loadcenter runs $110.00. They tell me the demand pretty much regulates the prices. They also sell a 5/8" x 8' ground rod for $2.00 less than a 1/2" x 8'. They simply sell more 5/8" rods.
