Installing 120V Circuits
Establish which lines will be the most critical to you in the time of a power outage. For example, let’s assume that switch 3L will be designated to supply power to the kitchen lights.

Turn oﬀ the corresponding kitchen light circuit breaker. Undo the screw that secures the wire to the circuit breaker, then disconnect the wire from the circuit breaker.
On the transfer switch, ﬁnd the wires marked with the number 3L, there should be one black and one red.
As figure 2 shows, feed the red 3L wire into the kitchen light breaker. Strip approximately 5/8″ off from the end of the wire, connect the stripped red wire to the kitchen light circuit breaker and tighten the screw.

Cut the black 3L wire to a similar length for aligning with the wire removed from the kitchen light circuit breaker in step a above. Strip approximately 5/8″ from the end of the black wire. Connect black 3L wire and the wire that was removed from the circuit breaker in step a by twisting a wire nut.
This completes the installation of the transfer switch for backup power to your kitchen light.
Repeat steps a – e for each of the remaining circuits.

Installing 240V Circuits
Establish which 240V lines will be the most critical to you in the time of a power outage. For example, let’s assume that switch 1L and switch 2L will be designated to supply power to the pump.

Turn oﬀ the corresponding pump circuit breakers. Undo the screws that secure the wires to the circuit breakers. Then disconnect the wires from the circuit breakers.
On the transfer switch, ﬁnd the wires marked with the number 1L and number 2L, Each number shall have one black wire and one red wire.

As ﬁgure 2 shows, feed both red wires into the pump breakers. Strip approximately 5/8″ oﬀ from the end of the wire, connect the stripped red wire to the pump circuit breaker and tighten the screws.
Cut both black wires to a similar length for aligning with the wires removed from the pump circuit breaker in step a above. Strip approximately 5/8″ from the end of the black wires. Connect black wires and the wires that were removed from the circuit breakers in step a by twisting wire nuts.
This completes the installation of the transfer switch for backup on your pump. Repeat steps a-e for each of the remaining circuits.

Completing the Installation
When you have wired all the load circuits in the transfer switch, only the white neutral wire and the green ground wire remain.

Insert the white neutral wire into an unused opening in the neutral bar in the load center and tighten the screw (Figure 2).
Insert the green ground wire into an unused opening in the ground bar, if existing, and tighten the screw. If no ground bar exists, insert the green wire into an unused hole in the neutral bar and tighten the screw.

Replace the cover to the load center.
Fill in the chart on the transfer switch to identify your emergency circuits and corresponding circuit numbers in the load center.
Return all load center branch circuits and main breakers to the “ON” position.

Move all rocker switches on the transfer switch to the “L” position. Installation is now complete.

Connect Your Power Transfer Switch to Generator
Once the Power Transfer Switch has been successfully installed, you can now connect your Power Transfer Switch to your Generator by using the included power cord. The steps below are using Nature’s Generator Powerhouse as an example.

Fit the female connector of the included power cord into the power inlet of your PowerTransfer Switch. Turn the connector clockwise to secure the connection.

Insert the male connector of the included power cord into the AC outlet on the generator.

Use Your Power Transfer Switch

Once you’ve connected the Power Transfer Switch to the Nature’s Generator Powerhouse, now when there is no utility power, you are still able to power your most important electrical items.
