I`m looking at leasing a office unit with what ive been told has "60 amp 600 volt" electrical capacity. The unit can be upgraded to 100amp with an additional 45KVA transformer. at its current 60amp limit how many 8 core MACPROS with 30' apple monitors can I have running at once? at 100amp limit how many? Im not sure if air con is powered separately to the main supply. For this calculation Im assuming NOTHING else is using this circuit. many thanks for opinions!
