5. Installation and Setup
Proper installation is crucial for the safe and efficient operation of your automatic transfer switch. Always ensure all power sources are disconnected before beginning any wiring work. It is recommended to consult a qualified electrician.
5.1 Wiring Diagram
The unit includes a wiring schematic on the inside cover for detailed connection instructions. This diagram illustrates connections for Generator, Shore Power, and the AC Panel. Key connections include:
- Hot and Neutral (Neu) connections for Generator, Shore Power, and the Panel.
- Ground Bar Data: Torque specifications for #4 - #6 (35 IN.LBS), #8 (30 IN.LBS), and #10 - #14 (25 IN.LBS) wires.
- Time Delay / Relay Control: Connections for Yellow (Yel), Black (Bk), White (Wht), and Red (Red) wires.
- Maximum Service: 120V 60Hz 1 Phase 30A/Pole 2 Pole.
- Time Delay: 20-45 Seconds (voltage must exceed 90V) for general loads.
- Continuous load current should not exceed 100% of the switch rating.
Use copper wire only, 75C minimum. When using conduit, the hub must be assembled to the conduit before the hub is installed in the enclosure.

6. Operating Instructions
The 5100 Series Automatic Transfer Switch operates automatically to switch between available 120 VAC power sources. When both shore power and a generator are connected, the switch prioritizes the generator. Once the generator is shut off, the switch will automatically transfer back to shore power after a built-in time delay (20-45 seconds) to ensure voltage stability. This automatic operation ensures a seamless power transition to your RV's AC panel.
7. Maintenance
Regular inspection of the transfer switch and its connections is recommended to ensure continued safe and reliable operation. Check for any loose wiring, signs of wear, or corrosion. Keep the unit free from dust and debris. If the circuit board requires replacement, the quick-change design allows for easy servicing without disconnecting the entire unit. Always disconnect all power sources before performing any maintenance.
8. Troubleshooting
If the transfer switch is not operating as expected, consider the following:
- No Power Transfer: Ensure both power sources (shore power and generator) are providing adequate and stable voltage. Check all wiring connections for tightness and proper contact.
- Delayed Transfer: The unit has a built-in time delay of 20-45 seconds when switching from generator to shore power. This is normal operation to allow generator voltage to stabilize.
- Intermittent Power: Check for loose connections at the terminals or within the pigtail connectors. Verify that the continuous load current does not exceed the switch's rating.
- Unit Malfunction: If issues persist after checking connections and power sources, the quick-change circuit board may need inspection or replacement. Contact customer support or a qualified electrician.
