A reverse polarity indicator is placed between which two wires?

A reverse polarity indicator is designed to detect incorrect wiring orientations, particularly in AC circuits where the hot and neutral wires may be improperly connected. The placement of the indicator is specifically between the white neutral wire and the green grounding wire.

In AC systems, the neutral wire serves as the return path for current, while the grounding wire is a safety feature that helps prevent electric shock by providing a path for fault currents. If the hot wire is accidentally connected to what should be the neutral wire, this creates a reverse polarity situation, which can lead to unsafe conditions. The reverse polarity indicator, when placed between the neutral and grounding wires, detects this fault and alerts the user, enhancing safety by indicating that the circuit is wired incorrectly.

This configuration is significant because it enables the detection of potential hazards without having to check the entire circuit, thereby promoting safer electrical practices in marine environments.
