A "y" adapter for supplying power to a marine vessel from a dockside pawer center having two receptacles includes two three-pole plugs insertable into the receptacles, a third four-pole plug for connection to the wiring system of the vessel and a sensing and control unit for selectively switching paths between these plugs. All conductor lines are switchable to the third plug and between the input plugs by a voltage and phase sensing unit and contactor arrangement. Energization of one input plug while the other one is plugged into a receptacle is prevented and other dangerous voltage circumstances are also prevented.

Why it's free to use
- Filed November 22, 1990 and granted August 31, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 22, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 22, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
