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. |
