Abstract

A reverse fed single pole miniature ground fault circuit breaker includes a housing, a line termination on the lower portion of the housing, and a load termination on the upper portion of the housing. Separable contacts are disposed between the line termination and the load termination. A handle and operating mechanism form a manual mechanism for manually operating the separable contacts. The handle has an upper position in which the separable contacts are closed and a lower position in which the separable contacts are open. A ground fault circuit interruption trip circuit opens the separable contacts in response to predetermined ground fault current conditions and is powered through those separable contacts. In this manner, when a power source is electrically interconnected with the line termination on the lower portion of the housing, when the handle is in the upper position, and when there is none of the predetermined ground fault current conditions, the ground fault circuit interruption trip circuit receives power through the separable contacts.
