Hopefully I am not asking a question already posted. I have seen some questions related to residential service sizes, but nothing to answer my questions. We are involved in a project that is installing 1 hp, 240v, 1ph sewer grinder pumps in residential neighbor hood. Each home owner is getting one. We instructed the electrician to provide a service calculation for each resident to determine if a service upgrade is needed. The calculation was based on Example D2(b) of the 2005 NEC. First question - if the calculation totals 85 amps (including new load) will the existing 100 amp service be adaquate per code? Where would an upgrade be required, over 100 amps? I would contend the countertop mounted microwave is not a fixed appliance and would be included in the small appliance load - yes/no? I have seen from some other posts that it is possible to have more than 2 small appliance circuits. Has anyone seen 4, 5 or 6 small aplliance circuits? Some of the residental calculations have that many. If a circuit is dedicated to the countertop is that what will label it as a SAC? Any insight would be appreciated.
