Using this circuit breaker is easy. First, make sure your electrical system's voltage and amperage match the breaker's specifications. Mount it on a panel using the #10 (M5) screws through the recessed mounting holes. Connect the heavy gauge wire lugs to the 5/16' - 18 terminal studs and tighten them to the recommended torque of 75 in-lb (8.47 Nm). The large lever on the breaker will show its status - vertical or horizontal orientation indicates trip status. Remember, don't use it as a switch when high inrush currents are expected. For maintenance, check the breaker regularly for any signs of damage or overheating. Keep it clean and dry as it's waterproof but still needs proper care. If it trips, find and fix the cause before resetting it manually. It's designed for a long service life, but if you notice any issues, consult a professional electrician.
