3. Installation
Proper installation is critical for the effective operation of the IG1240RC3. If you are not comfortable working with live electrical panels, please contact a qualified electrician.
Installation Steps:
- Disconnect Power: Locate your main electrical service panel and turn off the main breaker to completely disconnect power to your home. Verify power is off using a voltage tester.
- Select Mounting Location: Choose a suitable location near your main electrical panel or utility meter cabinet. The device should be mounted securely to a wall or directly to the panel enclosure.
- Mount the Device: Secure the IG1240RC3 using appropriate fasteners. Ensure the device is oriented so the LED indicator is visible.
- Connect Leads: The device has four 30-inch, 12-gauge leads. These leads must be connected as follows:
- Connect one lead to the neutral bus bar.
- Connect one lead to the ground bus bar.
- Connect the remaining two leads to a dedicated 2-pole, 20-amp circuit breaker within your electrical panel. This breaker should be connected to opposite phases of your 120/240V service.
- Manage Wiring: When routing the leads, avoid sharp 90-degree bends. Maintain a gradual curve (approximately 4 inches radius) to optimize surge protection performance. Ensure all connections are tight and secure.
- Restore Power: Once all connections are made and verified, close the electrical panel cover. Turn the main breaker back on.
