There is a 500KVA transformer feeding a 1200A a service entrance for a building. The Load factor for that building is 65.98 and the KW is 17.6 and the KWH for that building is 8640 ...(info from the elec.bill)...

The question:- How do i work out what the remaining amperage is for that 1200A SES from the said infomation or what other info do i need to know to get my answer.
with thanks

What you need is the maximum KW or KVA demand that is available from the utility billing dept. The KW you show, 17.6, seems too low. KWH's does not tell you anything. I'm not sure what you are calling "load factor" has to do with your billing. Check with the utility to clear this up.
Get the max KW and the amps demand = KW x 1000/(1.73 x volts x power factor). What is the voltage?
