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