Abstract: A leakage current protection system includes a current transformer disposed about current-carrying conductors that extend from first ends to second ends. The first ends are coupled to load receptacles. The current transformer detects an aggregate differential current between the conductors. Each of a plurality of circuit breakers is coupled to the second ends of the conductors that are coupled to a corresponding one of the load receptacles. Each circuit breaker is coupled to a source of electrical power. A differential current monitor coupled to the current transformer generates a signal when the aggregate differential current exceeds a threshold current. Each of a plurality of shunt-trips coupled to the differential current monitor receives the signal. Each of the shunt-trips opens a corresponding one of the circuit breakers when the signal is received so that all of the circuit breakers are opened simultaneously.
Abstract: A receptacle breakaway system for power pedestals includes an electric power receptacle having a body and mounting ears with an axis passing through the body and mounting ears. A mounting plate having a hole passing there through is configured for passage of the receptacle's body wherein the mounting ears engage a face of the mounting plate. A first retainer is rigidly coupled to the mounting plate at a first position offset from the receptacle's axis. The first retainer extends at least partially over a first of the mounting ears. A second retainer is rigidly coupled to the mounting plate at a second position offset from the receptacle's axis. The second retainer extends at least partially over a second of the mounting ears. The receptacle's axis passes between the first position and second position.
Abstract: A power housing assembly includes a housing having a side thereof that is at least partially open. A faceplate, coupled to the open side at a first hinge position, can articulate about the first hinge position between a first position and a second position. The faceplate includes a substantially L-shaped portion that resides (i) in the housing when the faceplate is in its first position, and (ii) outside of the housing when the faceplate is in its second position.

Abstract: A transformer system includes a cabinet and at least one toroidal transformer with each toroidal transformer being supported in a cradle. Each cradle is mounted in the cabinet and supports its toroidal transformer in a vertical or horizontal orientation such that a central air-filled region thereof is arranged in a substantially horizontal or vertical orientation, respectively. The cradle supports active and passive cooling arrangements for the toroidal transformer, while also providing modular attributes for the transformer system.
