WEN 56405 Power Pro 4050 Watt - Manual (Page 21)

If these specifications are not available, you may estimate the Watts required by your device using
the chart in figure 10.
When the running wattage requirement of each electrical device has been determined, add these
numbers to find the total running wattage needed. If this number exceeds the running wattage of
the generator, DO NOT connect all these devices. Select a combination of electrical devices,
which has a total running wattage lower than or equal to the running wattage of the generator.
CAUTION: The generator can run at its surge wattage capacity for only a short time.
Connect electrical devices requiring a rated (running) wattage equal to or less than the
running wattage of the generator. Never connect devices requiring a running wattage equal
to the starting wattage of the generator. This can trip the circuit protectors (circuit
breakers).
