Connect heavy gauge wire lugs to the terminal studs, which can handle a good amount of current. The large lever makes it clear to see the trip status. Just operate the lever to switch it on or off. When it comes to safety, don't use it as a switch where high inrush currents are expected. The breaker is ignition protected, so it's safe for gasoline-powered boats. In terms of maintenance, keep it in a clean and dry place. The waterproof feature helps, but avoid exposing it to extreme conditions. Check the terminal connections regularly to ensure they're tight, and make sure the operating temperature stays between -40° C and 85° C.
