* Permissible limits of the voltage range at which the unit operates satisfactorily.
# Unit ampacity = 125 percent of largest operating component’s full load amps plus 100 percent of all other 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 furnace and service panel for maximum 2 percent voltage drop.
