1. When would I need a generator:
Generators are very handy to have in the event the power
goes out because of a storm or other natural event. They
are a good backup system for heaters, freezers, well pumps
and lights.
There are two different types of generators available. The
first are the Portable models. These are very popular for
those who need to run equipment away from electricity. Many
are available for light duty residential use, while others
are rated for heavier commercial and industrial use.
The second type is a fully automatic permanently installed
unit attached to a home or business.
Both have dual-fuel capability.
2. What is a permanent unit:
Permanent units are fully automatic generators that can
be installed next to a home or business in a fixed location.
These units typically can perform such functions as monthly
self-tests and systems checks. They generally are directly
wired into the main breaker panel and can operate the entire
facility or a part of it in the event of an outage. In addition,
they automatically turn themselves on when they sense a
power failure.
While these units are the most expensive to purchase,
they are also the most convenient to operate.
3. How do I connect my portable generator safely:
There are two ways to connect a generator.
First, you can plug your appliances directly into the generator
and run them as needed.
Second, you can have the generator connected to your breaker
panel, by a licensed electrician, through a transfer switch.
This enables you to throw the switch and have the items
that you have designated as important continue to operate
from the generator.
VERY IMPORTANT NOTICE: The main breaker
on your panel does not qualify as a transfer switch under
the National Safety Code. Using it in such a manner is illegal!
4. Do I need any permits:
Yes. If you choose to have the transfer switch installed
the electrician will get the necessary permits for the job.
If you choose to operate a portable generator with items
plugged into it, you do not need a permit.
However, please let your local utility know that you are
running a generator. Line crews may pass you by if they
see lights on.
Also, crews in the area can plan on working in the vicinity
of an operating generator.
5. Can someone or something be hurt by a generator:
Yes. Emergency generators pose safety hazards you may not
be aware of.
Transfer switches are required because electricity from
the generator can be sent through the meter base and into
the distribution lines. This could be life-threatening to
workers, neighbors, children or animals in the vicinity
of a downed power line.
In addition, when power is restored it will flow back
to your home, and can seriously damage or destroy a generator
that does not have approved safety switching.
6. Who can help me do this?:
Your local utility can provide you with information and
assistance on generator installation and safety.
They can also help you contact the appropriate people
to size, connect and maintain your unit once you have decided
you want to seriously consider a generator.
