Single Phase Load
Always be sure to check the nameplate on the generator and equipment to insure the wattage, amperage and frequency requirements are satisfactorily supplied by the generator for operating the equipment.
Generally, the wattage listed on the nameplate of the equipment is its rated output. Equipment may require 130— 150% more wattage than the rating on the nameplate, as the wattage is influenced by the efficiency, power factor and starting system of the equipment.
If wattage is not given on the equipment's
NOTE name plate, approximate wattage may be determined by multiplying nameplate voltage by the nameplate amperage.
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 1.0 See Table 2 below when connecting loads.

MQ GA-2.9R— LOAD APPLICATION
To determine the running wattage for your load, multiply the running wattage as indicated by steps 1, 2, and 3 below:
1.INCANDESCENT LOADS
Lights, heaters and similar appliances. Total the running wattage and multiply by 1. Example:
29 light bulbs @ 100W each = 2.9 KW use a 3 KW generator.
2.SMALL MOTORS
Drills and other small power tools.
Total the running wattage and multiply by 2. Example:
A 1 inch drill runs at 1 KW use a 2 KW generator.
3.LARGE MOTORS
Submersible pumps, table saws etc.
Total the running wattage and multiply by 3. Example:
A conveyor belt runs at 8 KW use a 24 KW generator.
CAUTION
Motors and
Extension Cables
When electric power is to be provided to various tools or loads at some distance from the generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the generator and point of use (load) is held to a minimum. Use the cable selection chart (Table 3 ) as a guide for selecting proper cable size.
