1. A system, comprising:
- a power distribution center, comprising;
an enclosure comprising an access door configured to move between a closed position and an open position;
a non-contact sensor disposed inside the enclosure, wherein the non-contact sensor comprises a non-contact voltage sensor, or a non-contact temperature sensor, or a combination thereof;
a monitoring system communicative with the non-contact sensor to monitor one or more components within the enclosure, wherein the non-contact sensor is electrically isolated from the monitoring system and the one or more components; and
an indicator viewable outside of the enclosure while the door is in the closed position, wherein the indicator is coupled to the non-contact sensor.

Abstract
A system, in one embodiment, includes a power distribution center having an enclosure with an access door configured to move between a closed position and an open position. The power distribution center includes a non-contact sensor disposed inside the enclosure, wherein the non-contact sensor includes a non-contact voltage sensor, or a non-contact temperature sensor, or a combination thereof. The power distribution center also includes an indicator viewable outside of the enclosure while the door is in the closed position, wherein the indicator is coupled to the non-contact sensor.

13. A system, comprising:
a power distribution center, comprising; an enclosure comprising an access door configured to move between a closed position and an open position; a non-contact voltage sensor disposed inside the enclosure, wherein the non-contact voltage sensor is configured to sense voltage of a group of components; and a monitoring system communicative with the non-contact voltage sensor, wherein the monitoring system comprises a sensor baseline setup having a plurality of voltage measurements for the non-contact voltage sensor, the plurality of voltage measurements correspond to different permutations of the components being turned on and off, and the monitoring system is configured to compare the sensor baseline setup against actual voltage measurements during operation of the power distribution center to determine power states of individual components in the group; and an indicator coupled to the monitoring system. - View Dependent Claims (14, 15, 16, 17)
