GENERATOR APPLICATION

WHAT IS A GENERATOR
A generator is basically a prime mover, typically a
gasoline or diesel engine, coupled to an alternator to
produce electricity. It is very useful as a substitute power
source during power outages or as the primary source in
remote locations where
Generators are essential for people such as contractors
or farmers who are always in need of portable power.
They are also very convenient for recreational use.
SELECTING A GENERATOR
Selecting the proper generator is important. A generator
that is too small for your application will not run all of the
equipment needed. A generator that is too large will cost
more and if never used to its potential the money is
wasted. The correct size generator is determined by
totaling the wattage requirements of the items to be used
simultaneously, determine additional starting wattage
requirements and total these numbers. Select a generator
with a continuous rating that exceeds this by about 20%
to allow for expansion. See the table in the section titled
"Generator Set Overload" for some wattage guidelines of
common equipment.
RATED vs. SURGE WATTS
Rated, or continuous, watts are the watts an item needs
as it is running.
Surge, or maximum, watts are the watts an item needs to
start. This is typically 2-4 times the rated watts.
This information is
manufacturer's nameplate. If watts are not provided, it
can be calculated using the formula: Watts=Amps x Volts.
EXTENSION CORDS
An extension cord should always be in good condition
with no damage to the wires or sheathing. Never run an
extension cord through water. The correct wire size for an
extension cord can be determined from the table that
follows.

LOADING YOUR GENERATOR SET

With reference to the Receptacle details section, please
review the power receptacles fitted to your generator. The
circuit breaker rating and the generator rating drive the
actual load that may be pulled from each receptacle. The
ratings shown in the table are the maximum available from
each receptacle. DO NOT EXCEED THE INDIVIDUAL
RECEPTACLE RATINGS AS SHOWN IN THE TABLE
BELOW. DO NOT EXCEED THE TOTAL GENERATOR
RATING SHOWN
SPECIFICATIONS. All generator units are equipped with
a thermal-magnetic main circuit breaker as well as a
"PUSH TO RESET" breaker on branch circuits.

ENGINE LIMITATIONS ON GENERATOR
Generator ratings assume 60F (20C) and Sea
Level. Operation of your generator at temperatures
above 60F (20C) or above Sea Level will result in
lower electrical output. Electrical output must be
derated 1% for each 10F above 60F and 3 ½ %
for each 1000 feet above mean sea level.

GENERATOR CLEANING

CAUTION:
GENERATOR AND ALLOW IT TO COOL
COMPLETELY
CLEANING OPERATIONS.
WARNING: DO NOT USE HIGH PRESSURE
WATER OR A GARDEN HOSE TO CLEAN
YOUR GENERATOR. WATER INTRODUCED
INTO THE GENERATOR CAN CAUSE ELECTRICAL
SHORTS, GENERATOR DAMAGE OR PERSONAL
INJURY.

Compressed air (max. 25 psi) may be used to blow
loose dirt and dust from your generator. DO NOT
DIRECT COMPRESSED AIR DIRECTLY INTO ANY
OPENING IN THE GENERATOR OR ENGINE.

Use a dampened cloth to wipe clean exterior
surfaces.

Use a soft bristle brush to clean/ loosen heavy dirt, oil
or grease deposits.

NEVER insert rags, tools or any device into the
generator or engine openings.
