That's my point. Put a diode in the reverse of the expected polarity, and that circuit powers a buzzer. That circuit is always on (regardless of the state of the breaker). If reverse polarity occurs, it buzzes.

2. If you close the breaker, death will occur.
Yes, but the buzzer sounds as soon as you connect a battery with the reverse polarity. If you close the breaker while the buzzer is sounding ... Well, that's your fault.

The situation it does not solve is if you reverse wire the breaker to the PDP.
