Using this Blue Sea battery selector switch is easy. First, choose the right mounting option - you can mount it on the surface, rear, or front panel. Connect your battery cables (up to 4/0 AWG) to the tin - plated copper studs. You'll feel the tactile indicator to know the knob position. When using, you can switch between battery banks without any power interruption thanks to the make - before - break contact design. As for precautions, since it's for gasoline - powered boats, make sure it's installed correctly to ensure ignition protection. And it's waterproof, but don't submerge it for a long time. For maintenance, regularly check the terminal stud torque to keep it at 220 in - lb (24.86 Nm). Also, check for any signs of corrosion on the tin - plated copper studs and clean them if necessary.
