| Internal P.C. Board Senses That: - Both plugs are fully engaged (i.e., one is not dangling loose while the other is plugged in). - The polarity of the 30A receptacle on the dock is correct (i.e., no mis-wiring of the hot and neutral wires). - The two 30A receptacles are from opposite phases (i.e., there is a true 250V available instead of just 125V). | | Application: Problem: A boat owner with a 50A 125/250V electrical system on board cruises into a marina that can only provide 30A 125V power. Solution: Use of the Hubbell YQ230 Intelligent Adapter permits the boat owner to use the boat's 50A 125/250V cable set and safely plug into 2 oppositely phased 30A 125V receptacles. Result: This will result in 30A 125/250V power so that much of the boat's services can be used: Safely -- If one plug is not fully engaged, or accidentally becomes disengaged while the other plug is plugged in, the power is shut off preventing the disengaged plug from ever becoming hot or live! Intelligently -- If an improper wiring condition such as reversed polarity exists on the power center, the YQ230 detects that and shuts the power off. Also, the YQ230 will work regardless of whether the marina is powered with a 125/250V system or a 3-phase 120/208V system. |
