Using this Blue Sea circuit breaker is easy. First, mount it on a surface using #10 (M5) screws through the recessed mounting holes. Connect heavy gauge wire lugs to the terminal studs with the right torque (75 in-lb or 8.47 Nm). You can tell the trip status from the large lever's orientation. Remember, don't use it as a switch when there are high inrush currents. Keep it in an environment between -40° C and 85° C. It's waterproof, but try to avoid excessive moisture. Check the terminals regularly for tightness and clean the case with a dry cloth. If it trips, manually reset it according to the Type III class rules. It's safe for gasoline-powered boats as it's ignition protected, but always follow safety guidelines.
