Abstract: A ground fault protection system and method for implementing such is provided for protecting an electrical power distribution system having multiple sources and multiple grounds. A set of current transformers are connected to an interface unit which in turn is connected to a ground fault trip function for a circuit breaker. The interface unit has an output with a low impedance, and the outputs of multiple interface units can be connected in series and feed a single ground fault trip function; thereby tripping the circuit breaker on a ground fault detected by any set of current transformers connected to one of the interface units. Another embodiment utilizes multiple, independent ground fault trip functions in a single circuit breaker. Each ground fault trip function is connected to a set of current transformers, and the circuit breaker will trip if any connected set of current transformers detects a ground fault.

Abstract: An electrical enclosure having continuous front accessible dedicated wiring compartments. The dedicated wiring compartments provide the installer with easily accessible front wiring compartments. Each dedicated wiring compartment contains wiring for a specific function. The dedicated wiring compartments are configured to provide a continuous front accessible wiring compartment for multiple enclosures installed immediately adjacent one another. Horizontal frame members of the electrical enclosure provide a significant part of each dedicated wiring compartment.
