2. Safety Information

WARNING: Risk of Electric Shock. Disconnect all power sources before servicing.

• More than one live circuit: Always disconnect all sources of supply before servicing this device. Failure to do so can result in severe injury or death.
• Do not remove cover with voltage present: Ensure all power is off before opening the unit.
• Mounting: Do not mount with the cover face down (parallel to earth).
• Wiring: Use copper wire only.
• Wire Specifications: Use 75°C wire, 300V, No. 10 AWG supply conductors.
• Strain Relief: Suitable strain relief for conductors must be provided at installation.
• Current Rating: Continuous load current must not exceed 100 percent of the switch rating (30A).
• Application: This automatic transfer switch is for use only in optional standby systems.

3. Setup and Installation

Installation of this transfer switch should only be performed by a qualified electrician in accordance with all local and national electrical codes.

3.1 Pre-Installation Checks

• Verify that the electrical system voltage and current match the switch specifications (120V, 30A, 60Hz).
• Ensure you have all necessary tools and materials, including appropriate copper wiring (No. 10 AWG, 75°C rated).
• Confirm that the mounting surface is stable and suitable for surface mounting.

3.2 Mounting the Switch

1. Select a suitable location for surface mounting, ensuring it is not with the cover face down.
2. Securely mount the transfer switch to the chosen surface using appropriate fasteners.

3.3 Wiring Connections

1. Disconnect all power sources: Turn off the main utility power and ensure the generator is off and disconnected.
2. Remove the cover of the transfer switch.
3. Connect the utility power supply conductors to the designated 'INPUT' terminals using screw connectors. Ensure proper polarity.
4. Connect the generator power supply conductors to the designated generator input terminals.
5. Connect the load conductors (to the circuits you wish to power) to the 'OUTPUT' terminals.
6. Install suitable strain relief for all conductors entering and exiting the switch enclosure.
7. Double-check all connections for tightness and correct wiring according to the internal wiring diagram (if provided on the unit or in supplementary documentation).
8. Replace the cover securely.

4. Operating Instructions

The Southwire 41301-30A is an automatic transfer switch with a push-button actuator for manual override or selection. It is designed for a 2-way circuit type.

4.1 Automatic Operation

In normal operation, the switch automatically detects the presence of utility power. When utility power is lost, the switch will initiate a transfer to the generator source after a pre-set delay time (Generator to Shore Automatic). When utility power is restored, the switch will automatically transfer back to the utility source.

4.2 Manual Override (Push Button)

The unit features a push-button control for manual intervention. Refer to the markings on the unit for specific push-button functions, typically allowing for manual selection between utility and generator power or initiating a transfer cycle.

5. Maintenance

Regular maintenance ensures the longevity and reliable operation of your transfer switch.

• Annual Inspection: Have a qualified electrician inspect the unit annually.
• Cleanliness: Keep the exterior of the switch clean and free from dust and debris.
• Connection Checks: Periodically, with all power disconnected, check all electrical connections for tightness. Loose connections can cause overheating and potential hazards.
• Environmental Conditions: Ensure the operating environment remains within specified temperature and humidity ranges.

6. Troubleshooting

If you experience issues with your transfer switch, consult the following common troubleshooting steps. For complex problems, contact a qualified electrician.

• No Power to Load:
  • Check if both utility and generator power sources are active.
  • Verify that the transfer switch is in the correct position (utility or generator).
  • Inspect circuit breakers for both utility and generator inputs, and the load output.
• Switch Not Transferring:
  • Ensure the generator is running and producing stable power.
  • Check for any error indicators on the switch (if applicable).
  • Confirm that the delay timer has completed its cycle.
• Overheating:
  • Immediately disconnect power.
  • Check for loose connections or overloaded circuits.
  • Ensure the continuous load current does not exceed 30A.
