Using this Blue Sea circuit breaker is straightforward. First, make sure the power is off before installation. Mount it using the recessed holes for a clean look. Connect heavy gauge wire lugs to the terminal studs with large clearances. The single-lever operation makes it easy to switch on and off. When the lever shows the trip status, it means there's a fault current, and you should check the circuit. As for maintenance, keep it dry since it's waterproof but avoid extreme wet conditions. Check the terminals regularly to ensure high-torque connections. Remember, this product contains chemicals that can be harmful, so follow the warning on P65Warnings.ca.gov. Also, operate it within the -25°C to +82°C temperature range for best performance.
