Maximum distance for operating a load





MAXIMUM DISTANCE FOR OPERATING A LOAD
The distance at which the IIS Inverter will operate a load is determined by three things:

1) The wattage of the load
2) The voltage (120V or 277V)
3) The gauge of the wire

Below is a reference chart to help determine the distance (in feet) allowing for a 3% voltage drop.

120V 277V*
Watts 14 gauge 12 gauge 10 gauge 14 gauge
50 watts 1600 ft 2468 ft 4084 ft 8623 ft
100 watts 809 ft 1249 ft 2066 ft 4311 ft
125 watts 646 ft 997 ft 1649 ft 3445 ft
*Incandescent lamps are not generally operated above 140 volts except by special permission by the authority having jurisdiction.
