Yes. Not sure if the question is really asking about the max. residential service amperage. So, for the size of the largest service entrance conductor and associated size of grounding conductor, see ... http://www.cmapc.com/Elect%20Files/EHtmFiles/GECTable250-94.htm For the associated ampacities of those conductors, see ... http://www.cmapc.com/Elect%20Files/EHtmFiles/Table310-16.htm The table maxes out at 705 amps. To calculate the size of the service needed, go to the following webpage, select the cell "Sizing of Electrical Service", download the Excel spreadsheet, and enter the necessary info in the yellow squares. http://www.cmapc.com/_private/electsfr.htm Regards, Doug McKean ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
