Step 3: USING YOUR TRANSFER SWITCH:
A. Transferring from Utility Power to Generator Power:
1. Move generator outdoors. Then connect the male plug of the Power Cord into the correct
outlet on the generator and turn ON the circuit breaker (on generator) for the outlet
plugged into.
2. Plug in the female connector of the Power Cord to the Power Inlet Box or the power inlet
on the top of the PowerStay Manual Transfer Switch. Turn all circuit breakers in the
transfer switch to their OFF position.
3. Start the generator outdoors, following the procedures described in the generator’s
owner’s manual furnished by the manufacturer.
4. 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. Then turn ON any branch circuit breakers in the transfer switch that are OFF.
2. Shut down the generator, following the procedures in the generator Owner’s Manual.
3. Unplug the power cord from the generator and the power inlet.
4. 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.
