Using the Blue Sea 187-Series 30 Amp Surface Mount Circuit Breaker is easy. First, make sure to mount it on a flat surface using the provided mounting holes. Connect your heavy - gauge wire lugs to the terminal studs, which are designed to handle high - torque connections. The single lever is there for you to operate the breaker. When the lever is up, it's usually in the 'ON' position, and if it trips, it'll move to indicate the trip status. Just a reminder, don't use it as a switch in situations where there are high inrush currents. As for maintenance, keep it dry because it's waterproof, but it's still best to avoid long - term submersion. Check the terminal connections from time to time to make sure they're tight. Also, operate it within the specified temperature range of - 40°C to 85°C for optimal performance.
