# Unit ampacity = 125percent of largestoperating component's full load amps plus 100 percent of allother potential operating components' (EAC, humidifier, etc.) full load
amps.
Time-delay type is recommended.
Length shown is as measured one way along wire path between unit and service panelfor maximum2 percent voltage drop.
