2.3.2 CONNECTING THE GENERATOR TO A BUILDING’S ELECTRICAL SYSTEM
When connecting directly to a building’s electrical system, it is recommended that a manual
transfer switch is used. Connections for a portable generator to a building’s electrical sys-
tem must be made by a qualied electrician and in strict compliance with all national and
local electrical codes and laws.
Grounding the Generator
2.3.3 CONNECTING ELECTRICAL LOADS
DO NOT connect 240 (230) Volt loads to 120 (110) Volt receptacles.
DO NOT connect 3-phase loads to the single phase generator.
DO NOT connect 50 Hz loads to the 60 Hz generator,vice versa.
1. Let engine stabilize and warm up for a few minutes after starting.
2. Plug in and turn on the electrical loads.
3. Add up the rated watts (or ampere) of all loads to be connected at one time. This total
should not be greater than (a) the rated wattage/amperage capacity of the generator or
(b) circuit breaker rating of the receptacle supplying the power. See “Don’t Overload the
Generator”.
2.4 DON’T OVERLOAD THE GENERATOR
Overloading a generator in excess of its rated wattage capacity can result in damage to the
generator and to connected electrical devices. Observe the following to prevent overload-
ing the unit:
• Add up the total wattage of all electrical devices to be connected at one time. This total
should NOT be greater than the generator’s wattage capacity.
• The rated wattage of lights can be taken from light bulbs. The rated wattage of tools,
appliances and motors can usually be found on a data label or decal axed to the
device.
• If the appliance, tool or motor does not give wattage, multiply volts times ampere rating
to determine watts (volts x ampere=watts).
• Some electric motors, such as induction types, require about three times more watts
of power for starting than for running. This surge of power lasts only a few seconds
when starting such motors. Make sure to allow for high starting wattage when selecting
electrical devices to connect to the generator:
1. Figure the watts needed to start the largest motor.
2. Add to that gure the running watts of all other connected loads.
The Wattage Reference Guide is provided to assist in determining how many items the
generator can operate at one time.
