Reliance 510C Pro/Tran2 50-Amp 10-Circuit Manual Transfer Switch with Watt Meters

1. Introduction

The Reliance 510C Pro/Tran2 is a 50-amp, 10-circuit manual transfer switch designed to safely connect a portable generator to your home's electrical system. This unit allows you to power essential circuits during a utility power outage. It features integrated watt meters for monitoring power consumption. The Pro/Tran2 series is UL listed to UL standard 1008 and is suitable for use in accordance with Article 702 of the National Electrical Code ANSI/NFPA 70.

2. Safety Information

WARNING: Installation and servicing of this transfer switch must be performed by a qualified electrician in accordance with all national and local electrical codes. Failure to follow these instructions can result in serious injury, death, or property damage.

• Always disconnect utility power before working on the transfer switch or associated wiring.
• Ensure the generator is properly grounded according to its manufacturer's instructions.
• Never operate the generator indoors or in enclosed spaces. Generator exhaust contains carbon monoxide, which is a colorless, odorless, and deadly gas.
• Do not overload the transfer switch or the generator. Refer to the specifications section for maximum wattage and amperage ratings.
• Keep children and unauthorized personnel away from the transfer switch and generator during operation.

4. Installation

Installation of the Reliance 510C Pro/Tran2 transfer switch requires electrical expertise. It is strongly recommended that a licensed electrician perform the installation.

4.1 Mounting the Transfer Switch

The transfer switch should be mounted indoors, close to your existing main electrical panel. Ensure there is sufficient space for wiring and access to the circuit breakers and toggle switches.

• Select a suitable location on a wall near the main service panel.
• Mark the mounting points using the transfer switch enclosure as a template.
• Drill pilot holes and secure the transfer switch to the wall using appropriate fasteners.

4.2 Wiring Connections

The transfer switch connects to your main electrical panel and to an external generator inlet box (sold separately). The unit is pre-wired with flexible conduit containing the necessary conductors for connection to the main panel.

• Identify Circuits: Determine which 10 circuits from your main panel will be powered by the generator. These are typically essential loads such as furnace blowers, well pumps, refrigerators, and lighting circuits.
• Connect to Main Panel: The pre-wired conductors from the transfer switch must be connected to the corresponding circuits in your main electrical panel. This involves disconnecting the existing load wires from the selected circuit breakers in the main panel and connecting them to the transfer switch's load terminals. The transfer switch's line wires are then connected to the circuit breakers in the main panel.
• Generator Connection: Connect the generator input wires from the transfer switch to a properly installed 50-amp generator inlet box. Ensure correct phase, neutral, and ground connections.
• Breaker Configuration: The transfer switch includes circuit breakers. These may need to be reconfigured or swapped (e.g., changing a 20-amp breaker to a 15-amp breaker) to match the requirements of the connected circuits.

The flexible metallic conduit, containing the pre-wired conductors for connection to the main electrical panel, exits from the bottom right side of the unit.

5. Operating Instructions

The 510C Pro/Tran2 allows you to manually switch selected circuits between utility (LINE) power and generator (GEN) power.

5.1 Transferring to Generator Power

• Prepare Generator: Start your portable generator and allow it to warm up according to the manufacturer's instructions. Ensure the generator is producing stable power.
• Connect Generator: Plug the generator cord into the external generator inlet box.
• Turn Off Main Breaker: At your main electrical panel, turn off the main utility breaker. This prevents backfeeding power to the utility grid.
• Switch Circuits: For each circuit you wish to power with the generator, firmly and swiftly move the toggle switch on the transfer switch from the 'LINE' position (utility) to the 'GEN' position (generator). There is a center 'OFF' position for each switch.
• Monitor Watt Meters: The integrated watt meters provide real-time feedback on the power being drawn by the connected circuits. Monitor these to ensure you do not overload your generator.

5.2 Transferring Back to Utility Power

• Switch Circuits to LINE: For each circuit powered by the generator, firmly and swiftly move the toggle switch from the 'GEN' position back to the 'LINE' position.
• Disconnect Generator: Unplug the generator cord from the inlet box.
• Shut Down Generator: Turn off your portable generator according to its manufacturer's instructions.
• Restore Main Breaker: At your main electrical panel, turn on the main utility breaker.

6. Maintenance

The Reliance 510C Pro/Tran2 transfer switch is designed for long-term reliability with minimal maintenance. However, periodic inspection is recommended.

• Visual Inspection: Annually, or after any significant electrical event, visually inspect the transfer switch for any signs of damage, loose connections, or corrosion.
• Cleanliness: Keep the area around the transfer switch clean and free from dust and debris.
• Professional Check: Consider having a qualified electrician inspect the unit every few years to ensure continued safe operation.

7. Troubleshooting

If you encounter issues with your transfer switch, consider the following common troubleshooting steps:

• No Power to Circuits (Generator):
  • Ensure the generator is running and producing power.
  • Verify the generator cord is securely plugged into the inlet box and the transfer switch.
  • Check that the individual circuit toggle switches are firmly in the 'GEN' position.
  • Confirm that the circuit breakers within the transfer switch are not tripped. Reset if necessary.
  • Check the generator's circuit breakers.
• Overload Indication (Watt Meters):
  • If the watt meters indicate an overload, reduce the number of appliances or devices connected to the generator.
  • Ensure the total wattage of connected loads does not exceed the generator's capacity or the transfer switch's 12000-watt rating.
• No Power to Circuits (Utility):
  • Ensure utility power has been restored.
  • Verify the main utility breaker in your main panel is ON.
  • Check that the individual circuit toggle switches are firmly in the 'LINE' position.

For persistent issues, contact a qualified electrician or Reliance Controls customer support.
