STEP 3: USING YOUR GEN/TRAN
®
TRANSFER SWITCH:
NEVER run portable generators indoors or in garages, basements, or sheds. Portable generators should always be used at least 5 feet away from windows, doors,
vents, or any other opening. Carbon Monoxide (CO) from a generator is deadly and can kill you in minutes. Read and follow all generator directions before use.
A. Transferring from Utility Power to Generator Power:
1. Move generator outdoors.
2. Connect the male plug of the Power Cord into the correct outlet on the
generator. Turn ON the circuit breaker for the outlet plugged into.
3. Plug in the female connector of the Power Cord to the Power Inlet Box or the
power inlet on the front of the transfer switch. Turn all circuit breakers in
the transfer switch to their OFF position.
4. Start the generator outdoors, following the procedures described in the
generator’s owner’s manual furnished by the manufacturer. Turn ON the
GENERATOR MAIN circuit breaker in the transfer switch. Turn ON circuit
breakers in the manual transfer switch one at a time alternating from phase
“A” and phase “B”. Watch the meters as you turn on successive circuits so
that the meters do not continuously exceed the maximum wattage of the
generator. It may be necessary to alternate the use of larger loads (furnace
motors, well pumps, freezers, etc.) to avoid overloading the generator. To
promote generator life, loads should be balanced on Phase “A” and “B” so
that the wattage reading on each meter is within about 1000 watts of the
other.
5. Test your circuits by using the wattmeters or determine wattage from that
shown on each appliance. Make a note of any excessive loads which must
be removed from a given circuit during generator operation in an emergency.
B. Transferring from Generator Power to Utility Power:
1. On the transfer switch, turn the GENERATOR MAIN breaker OFF and the
UTILITY MAIN breaker ON.
2. Turn ON any branch circuit breakers in the transfer switch that are OFF.
3. Shut down the generator, following the procedures in the generator Owner’s
Manual.
4. Unplug the power cord from the generator and the power inlet.
5. Cool off the generator and store in a dry, secured location.
To ensure that your generator will work properly when you need it, it is important
to start and run your generator under load
regularly and keep the tank filled with
fresh fuel. Perform the above steps at least ONCE A MONTH to keep the generator
properly “exercised.” It is not necessary to turn off any circuits in the MAIN load
center when operating the transfer switch.
