Using this Blue Sea circuit breaker is a breeze. First, make sure you're working in a safe environment and the power is off. Mount the breaker using the #6 - 32 stainless - steel mounting screws and tighten them to 6 in - lb (0.68 Nm). Connect your wires to the 1/4 - 20 tin - plated brass terminal studs, torquing them to 35 in - lb (3.95 Nm). Once everything is connected, turn the power back on. The flat rocker actuator makes it easy to switch the breaker on and off. When the breaker trips, it's a sign that there's an overcurrent situation. Don't try to force it closed; instead, check for any faults in your electrical system. This breaker can operate in temperatures from - 40°C to 85°C, but try to keep it within a normal range for better performance. Remember, this product contains chemicals that can be harmful, so follow the California Proposition 65 warning. For long - term use, periodically check the connections to make sure they're tight and there's no sign of wear. Also, note that it has a switching cycle of 10000, so don't expect it to last forever. If you notice any issues, it might be time to replace it.
