Abstract
A power pedestal including a receptacle, a circuit breaker electrically connected between a power source and the receptacle and including separable contacts structured to trip open and electrically disconnect the receptacle from the power source, a current sensor structured to detect current flowing to the receptacle, and a ground fault detection device structured to sense a ground fault based on an output of the current sensor and to control the circuit breaker to trip open the separable contacts in response to detecting the ground fault. The ground fault detection device has an adjustable range of ground fault protection.
Claims9
A power pedestal comprising:
- a receptacle;
- a circuit breaker electrically connected between a power source and the receptacle and including separable contacts structured to trip open and electrically disconnect the receptacle from the power source;
- a current sensor structured to sense current flowing to the receptacle;
- and
- a ground fault detection device structured to detect a ground fault based on an output of the current sensor and to control the circuit breaker to trip open the separable contacts in response to detecting the ground fault,
- wherein the ground fault detection device has an adjustable range of ground fault protection,
- wherein the circuit breaker includes a shunt trip input,
- wherein the ground fault detection device is structured to output a signal to the shunt trip input to control the circuit breaker to trip open the separable contacts in response to detecting the ground fault,
- wherein the ground fault detection device includes an adjustment unit including an adjustable member structured to allow a technician to adjust the level of ground fault protection of the ground fault detection device, and
- wherein the adjustable member is at least one of a dial and a dip switch.
