Raritan Reverse Polarity Alarm for Shore Power

Description

The Raritan Reverse Polarity Alarm helps boaters identify incorrectly wired 120V dockside shore power before relying on the connection. It is especially useful when traveling between marinas, where wiring quality and outlet condition can vary from pedestal to pedestal.

Reverse polarity occurs when the hot and neutral conductors are switched. Without a warning indicator, the boat owner may have no obvious sign that the incoming supply is wired incorrectly. A polarity alarm adds an important diagnostic layer by alerting the operator to this condition before normal shore power use continues.

Many boats already include a reverse-polarity light on the AC distribution panel, but an audible alarm can make the warning harder to miss. This product is an important safety aid for boats that connect to common 120V AC shore power outlets. For owners upgrading or replacing a shore-power warning system, the Raritan alarm provides a dedicated indication of reversed incoming polarity. Browse more shore power accessories.
