over outlets:
iF any circuit BreaKerS trip cHecK tHe FOLLOWinG:
1. Make sure that ALL circuit breakers are reset
before starting the Generator again.
2. Adjust the plugs so the loads are
shared across outlet circuits.
to achieve rated output from the Generator,
distribute loads over outlets.
The generator uses a 2‑circuit system to supply power to the receptacles. The loads must
be evenly distributed across receptacles to prevent overload on a single circuit. If the loads
being drawn are below the max rated wattage of the generator, yet the overload light begins
blinking or the generator shuts off, try redistributing plugs across receptacles.
120V Only (3-wire) adaptor cord connected to L14-30 receptacle:
If the overload light begins blinking or the Generator shuts off, too much wattage is being drawn from one
circuit even though the rated wattage of the Generator has not been reached. If an additional plug is connected
to one of the duplex receptacles, move the plug to the other duplex receptacle. Restart the Generator.
note: Only half the Generator’s rated wattage, or 3500W, will be delivered through
a 120V (3‑wire) adaptor cord. Exceeding this may cause overload.
240V cord connected to L14-30 receptacle:
The 240V cord will draw full wattage from both circuits. If further loads
are possible, distribute them across receptacles.
