Key Components:

  • Painted Steel Cabinet: Durable enclosure for outdoor installation.
  • 10-Circuit Breakers: Allows connection of up to 10 individual household circuits.
  • Manual Transfer Mechanism: Safely switches selected circuits between utility and generator power.
  • CS6375 Power Inlet: 50-Amp inlet for connecting a generator cord.
  • Watt Meters: Integrated meters to monitor generator load.

Setup and Installation

IMPORTANT: Installation must be performed by a qualified electrician in accordance with all applicable electrical codes.

  1. Location Selection: Choose a suitable outdoor location for the transfer switch, close to your main service panel and where the generator will be operated. Ensure it is accessible and protected from direct impact.
  2. Mounting: Securely mount the transfer switch to a sturdy surface using appropriate hardware.
  3. Wiring to Main Panel: Connect the transfer switch to your main service panel. This involves running circuits from the main panel to the transfer switch and connecting the generator input. The pre-wired flexible conduit simplifies this process.
  4. Generator Inlet Wiring: Ensure the CS6375 power inlet is correctly wired to the transfer switch. This inlet is designed for a 50-Amp generator connection.
  5. Circuit Selection: Identify the 10 essential circuits you wish to power with your generator (e.g., refrigerator, furnace, lights, well pump). These circuits will be disconnected from the utility and reconnected to the transfer switch.
  6. Final Connections and Testing: After all wiring is complete and verified, restore power and test the functionality of the transfer switch according to the operating instructions.

Operating Instructions

Follow these steps to safely operate your manual transfer switch during a power outage:

  1. Prepare Generator: Place your portable generator in a safe, well-ventilated outdoor area, away from windows and doors. Ensure it is properly fueled and maintained.
  2. Connect Generator: Plug your 50-Amp generator cord into the CS6375 power inlet on the transfer switch.
  3. Start Generator: Start your generator according to its manufacturer's instructions and allow it to warm up.
  4. Transfer Circuits: For each circuit you wish to power, move its corresponding switch on the transfer panel from the 'LINE' (utility) position to the 'GEN' (generator) position. Observe the watt meters to balance the load and avoid overloading the generator.
  5. Monitor Load: Continuously monitor the watt meters to ensure the total load does not exceed the generator's capacity.
  6. Return to Utility Power: When utility power is restored, first move all transfer switches from 'GEN' to 'LINE'. Then, shut down your generator and disconnect the generator cord.

Maintenance

The Reliance Controls R510A transfer switch requires minimal maintenance. Regular inspection is recommended to ensure continued safe operation.

  • Annual Inspection: Have a qualified electrician inspect the transfer switch annually. This includes checking all electrical connections for tightness, inspecting the enclosure for damage or corrosion, and verifying proper operation of the transfer mechanism.
  • Keep Clean: Keep the exterior of the transfer switch clean and free of debris. Do not use harsh chemicals or abrasive cleaners.
  • Inlet Cover: Ensure the CS6375 power inlet cover is securely closed when not in use to protect against moisture and debris.
