Abstract: A utility station or pedestal for a boat dock is formed of an upper portion hinged to a lower portion. The interface between the portions extends across the housing at an angle with respect to horizontal so that when the upper portion is swung into an open position, an electrical terminal block mounted in the lower portion is readily accessible for connecting power lines introduced through the bottom of the housing.

Abstract: A ballast circuit for limiting the kilovolt-ampere rating of a ballast required to operate a high pressure sodium lamp during starting, hot restart and lamp out conditions. The ballast circuit includes a voltage limiting or clamping circuit across the secondary of a ballast transformer which responds to the voltage level and the rate of change of voltage across the secondary to activate a switch during each half cycle that the lamp is not conducting current.

Abstract: A ballast circuit for limiting the kilovolt-ampere rating of a ballast required to operate a high pressure sodium lamp during starting, hot restart and lamp out conditions. The ballast circuit includes a voltage limiting or clamping circuit across the secondary of a ballast transformer which responds to the voltage level and the rate of change of voltage across the secondary to activate a switch during each half cycle that the secondary of the ballast transformer goes into saturation.

Abstract: A ballast circuit for driving a sodium vapor lamp includes a ballast transformer having a primary winding connected to a constant current power source. A secondary winding of the transformer is connected across the lamp. A high voltage oscillator responsive to the voltage across the lamp superimposes high voltage pulses across the lamp when the voltage across the lamp is above a predetermined level. A time delay circuit, triggered by the initial voltage across the primary winding when the power from the power source is turned on, opens a normally closed switch connected across the primary winding a predetermined time interval after the time delay circuit is triggered.
