• Breaker Requirement: A 2-pole circuit breaker (Schneider Electric recommends a 30-amp double-pole breaker) compatible with your load center.
• Location: Install the unit in the breaker slot closest to your main service disconnect for optimal performance.
• Grounding: Ensure your home's electrical system has adequate grounding.

3.2 Installation Steps

1. Power Disconnection: Turn off the main power supply to your electrical panel at the main service disconnect. Verify power is off using a voltage tester.
2. Mounting: Select an appropriate knockout on the electrical panel. Install the surge protection device by securing its threaded nipple through the knockout.
3. Breaker Installation: Install the required 2-pole circuit breaker into an available slot in your load center.
4. Wiring Connections: Connect the two black wires from the surge protector to the terminals of the newly installed 2-pole breaker. Connect the white (neutral) wire to the neutral bus bar and the green (ground) wire to the ground bus bar in the panel. Keep the wire leads as short and direct as possible to ensure the fastest response time during a surge.
5. Secure Wiring: Ensure all connections are tight and secure. Neatly route and secure the wires within the panel.
6. Restore Power: Close the electrical panel cover. Restore power to the main service disconnect.
