Description
Reverse Polarity Alarm An essential aid for traveling boaters when connecting to unfamiliar dockside power. The quality of marina wiring can vary greatly from place to place and from plug to plug.
That is why most boats designed to plug into shore power have a polarity indicator. It is usually a warning light on the AC electrical panel, although it can also be an audible alarm.
It is an important safety feature that few boat owners fully understand or appreciate. With a couple of exceptions, it should be standard equipment on every boat that is capable of plugging into a common 120-volt AC shore power outlet.
Its purpose is to allow the boat owner to verify that the electrical outlet on the dock is wired correctly. When the polarity is incorrect or reversed, it is because the hot and neutral wires are switched.
Without an indicator light, you will not know when this condition exists.

Electrical — frequently asked
- What’s the difference between marine wire and regular wire?
- Marine wire uses tinned (tin-coated) copper strands that resist the corrosion salt air causes, and it’s more finely stranded so it flexes with vibration without breaking. Standard automotive or household wire corrodes and fails much faster in a marine environment.
- How do I size a fuse for a marine circuit?
- Size the fuse to protect the wire, not just the device. Match the fuse rating to the wire gauge’s safe current capacity so the fuse blows before the wire overheats. When adding a new circuit, follow the wire manufacturer’s ampacity chart for the gauge and run length you’re using.
- Do I need a battery switch on my boat?
- A marine battery switch is strongly recommended. It lets you disconnect the battery for storage or service, isolate a failed battery, and — on multi-battery setups — choose which bank powers the boat. It’s a core safety and reliability component.
