Raritan Reverse Polarity Alarm – Critical Protection for Shore Power Safety
When docking at unfamiliar marinas, electrical safety is not guaranteed. The Raritan Reverse Polarity Alarm acts as your boat’s frontline defense against dangerous wiring faults, providing instant visual and/or audible alerts when dockside power is improperly connected. Improper wiring—particularly reversed hot and neutral conductors—can lead to equipment failure, shock hazards, or even fires.
This compact, easy-to-install alarm is designed to monitor 120V AC shore power connections, detecting reversed polarity or missing grounding before problems occur. Whether you're cruising between ports or docking at your home marina, the Reverse Polarity Alarm offers peace of mind and protection with every plug-in.

Why It Matters
Marina wiring conditions vary widely—what seems like a safe power source could hide critical faults. Without a reverse polarity indicator, boaters may unknowingly expose their onboard systems to reversed current, damaging sensitive electronics or creating dangerous shock risks.
By installing Raritan’s Reverse Polarity Alarm, you gain a fail-safe notification system that activates the moment an issue is detected. It’s not just recommended—it’s a fundamental part of any safe AC electrical setup onboard.
Frequently Asked Questions – Reverse Polarity Alarm
Q1: What does a reverse polarity condition mean on a boat?
It means the hot and neutral wires are reversed in the shore power source, potentially allowing electricity to flow dangerously through ungrounded paths—even when breakers are off.
Q2: What happens if I plug into a dock with reversed polarity and have no alarm?
You could experience shock hazards, failed appliances, or electrical fires without any warning. Sensitive systems might be damaged over time, or safety systems may not function properly.
Q3: Is this alarm compatible with both 30-amp and 50-amp shore power?
Yes, it is compatible with both—as long as it monitors a 120V AC circuit, which is standard for most boats. Always confirm voltage before installation.
Q4: How is the Reverse Polarity Alarm installed?
The unit wires directly into your shore power input line or AC panel, typically with minimal tools and a straightforward connection to your neutral and hot conductors.
Q5: Can the alarm be disabled or muted?
Some models include audible alerts with mute functionality, while others are visual-only (LED indicators). Choose based on your preference for alert type and environment.
