will not increase the electric power output, and it can cause problems with
your motors and other frequency sensitive equipment, such as clocks.
8. Put the transfer switch in the generator position.
9. Connect the electric load. Start the largest motor rst, adding other loads
when each successive motor reaches its full operating speed. Do not add the
loads too quickly. If the generator stops, repeat steps 2, 5, 6, 7 and 8.
10. Check the voltage often to make sure you are not overloading the generator.
If voltage falls below 220 volts for 120/240-volt service, or 110 volts for 120-
volt service, turn off some of the electric equipment to reduce the load.
11. When regular power is restored, switch the transfer switch into the regular
utility power source’s position. Then stop the standby generator. Turn on
electric loads as usual. The transfer switch should be used to switch load
from the generator. DO NOT USE THE FLEXIBLE CORD CONNECTOR
TO REMOVE OR DISCONNECT LOAD FROM THE GENERATOR.
Removing the exible cord connector from a loaded generator can cause
damage to the connector and/or electric shock.
12. Re-install the neutral grounding jumper to allow the generator to be used as
a stand-alone power source.
Follow the instructions in your generator manufacturer’s manual. Test operate
the generator unit – under load – at least once a month. Check for fuel leaks. Replace
or use the fuel supply periodically to prevent moisture condensation in the tank, gum
accumulation in the carburetor or fuel deterioration – loss of the volatile components.
Consider using a “fuel stabilizer” if recommended by the generator manufacturer.
These guidelines are not intended as a complete installation guide for all genera-
tors and transfer switches, or to relieve the user of meeting the National Electric Code,
applicable state or local ordinances or codes.
If questions arise in the application of this guideline, contact your electric utility, a
licensed electrical engineer, local or state inspector, or a licensed electrical contractor
for clarication and application of local ordinances and codes, to guarantee a reliable,
safe and economic installation.
The congurations illustrated by Figures 1, 2, 3, 4 and 5 will require some re-
working or restructuring of the electrical service into your house. Consult with an
electrician or with your utility if you have any questions, unless you are familiar with
the requirements of the National Electrical Code applicable to these situations.
• Test your standby generator in advance, before an emergency occurs, to make
sure it works and to familiarize yourself with the procedure.
• If wiring has been damaged or is defective, don’t use your standby generator
until you remove the defective circuit from the system.
• If wind, ice or an accident caused the power outage, your home wiring may
need to be repaired before you use the standby generator.
• Keep ashlights or lanterns handy so you have light if you need it.
• Do not fuel the generator while the generator is running, or if it is hot. Allow
the generator to cool before refueling.
