Overloaded Switchboard

Not open for further replies.
I have 20 roof-top HVAC units that serve 60 residential condos. Each unit draws 60 amps. Is there a code section that allows me justify a demand load of less than 1200A?

I looked quickly and I think not...

"220.53 Appliance Load ? Dwelling Unit(s)
It shall be permissible to apply a demand factor of 75 percent to the nameplate rating load of four or more appliances fastened in place, other than electric ranges, clothes dryers, space-heating equipment, or air-conditioning equipment, that are served by the same feeder or service in a one-family, two-family, or multifamily dwelling."

There are other sections that reference 100% for cooling equipment also.
