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?
