Standby Generators
Proper connection can save and protect generator
from feedback
Many of Roseau
Electric Cooperative members have generators to supply their emergency electrical
needs. It's important to use them safely and maintain them
properly to get the maximum benefit from your investment.
Safety
- A generator installation must have an approved double-throw
transfer switch. The National Electric Code and your Cooperative
requires this switch for two very good reasons.
First, it does
not allow electricity from the generator to flow backward into the
power lines. Without a double-throw disconnect switch, 240-volt
electricity may feed back to your transformer which steps it up to
7,200 volts. As a result, a line crew working on the line or
someone else who assumes the line is dead would be put in danger.
Second, the double-throw switch protects your generator from
damage when the electricity is restored.
Maintenance
- Many of Roseau Electric Cooperative's rural customers already have a pole-top or
grade level double throw disconnect for their standby generator
systems. Some preventative maintenance is required to ensure your
disconnect will work when needed.
Have the
remote switch on top of your pole checked periodically. This
switch should be exercised and lubricated to ensure it is working
properly. Also check the box for holes that would allow dirt to
infiltrate the switch mechanism. All holes (except drainage holes)
should be sealed with a good quality silicon caulk.
Always follow
the manufacturer's recommendations on how to use your generator.
If you have questions about purchasing or connecting a standby
generator, please contact your electrician or call us at 218-463-1543 or
888-847-8840. It will be well worth your time to
avoid costly and hazardous mistakes.
