We Know What You Need

Essential aid for traveling boaters when connecting to unfamiliar dock side 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 in to shore power have a polarity indicator. 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.

At Raritan, we offer dependability where it counts.
