Using this circuit breaker is easy. First, find a suitable panel location for mounting. Make sure to use #10 (M5) screws for a secure fit. Connect heavy gauge wire lugs to the terminal studs, which have plenty of space around them. The large lever can be used to operate the breaker, and its orientation will show you the trip status. When it comes to safety, don't use this breaker as a switch where high inrush currents are expected. The 'Trip Free' design means it will trip automatically during fault currents. This breaker is waterproof, but still keep it away from excessive moisture. For maintenance, check the terminals regularly to ensure high-torque connections. If you need to reset the breaker, use the manual reset function. It can operate between -40°C and 85°C, so avoid extreme temperatures. And since it's ignition protected, it's safe to install on gasoline-powered boats.
