I have made a control box for my pool pump. The buzzer is 110 mA the power needed is 12 Volt backup battery and 12 volt wall wart.
Do I need to place a fuse in the circuit, inside of the control box?
For instance, if the wall wart goes bad or too much voltage goes through the power jack, it may make the battery explode or get real hot! It may be a fire hazzard.
If so, what kind or type of fuse or breaker would I place in line for 110 ma buzzer and 12 volt wall wart?
