Buying
the right generator can seem like a formidable task.
But in just a few easy steps you can effectively and
confidently decided and choose which generator is
right for you.
-
Identify the tools and appliances you wish to
operate with your generator.
-
Determine
the required power for each item ( see appliance
data plate i.e.: watts of appliance).
-
Add
the required Watts of each item that will be running
simultaneously. Also allow for motor starting
of appliance * see chart
-
Choose
the generator that has rated Watts that meet or
exceed this total power.
Motor
Starting is an important consideration when buying
a generator. Keep in mind that induction type motors,
like those that run sump pumps, refrigerators and
compressors , typically require 2 to 3 times their
listed running watts to start.
Opposite
is a chart you can use to determine how many Watts
you will need to start up motors of various sizes
and types.
Please
note that power tools using a universal commutator
do not require any additional start up power.
The
table opposite lists tools and appliances you may
want to use with your generator.
With
each tool or appliance is listed the approximate running
watts for each.
NOTE:
Always consult the data plate on the tool or appliance
for accurate electrical information. The outlet configuration
of some units may require modification to achieve
maximum rated power.

MAX kVA: Some Manufacturers give ratings
in kVA by adding 25% to the power rating. This figure
is for comparison with these values. |
