    3va/sf * 900sf [COLOR=#ffffff]................[/COLOR]= 2700va
    2 S.A circuit @ 1500va ea = 3000va
    Subtotal[COLOR=#ffffff].........................[/COLOR]= 5700va

    From 220.42
    First 3000va @ 100%......= 3000va
    Remaining 2700va @ 35%= 945va
    From 220.55
    Range[COLOR=#ffffff]............................[/COLOR]= 8000va
    Total[COLOR=#ffffff]..............................[/COLOR]= 11945va

      I guess they assume a common laundry. I hate questions like that
      They say I shot a man named Gray and took his wife to Italy
      She inherited a million bucks and when she died it came to me
      I can't help it if I'm lucky
