A remote controllable monitoring system includes a movable sensor to monitor characteristic(s) of electrical components of equipment housed at different locations inside of an electrical enclosure. The movable sensor is movably mounted inside of the electrical enclosure. The monitoring system can also control the power supplied to the electrical components (e.g., turn power ON or OFF). A remote device interacts with the monitoring system to provide a user with remote control over the functions of the monitoring system. The remote device can include an interactive user interface with a virtual map of the electrical components. Accordingly, the user can monitor electrical components and turn OFF power to the electrical components if a problem or perspective problem is detected, via the interactive user interface of the remote device without opening or being near the electrical enclosure.

An antenna mount () is provided for an enclosure () of a panelboard. The mount includes an antenna cover () mountable on the enclosure via a hole on a wall of the enclosure. The cover includes an opening () at one end to receive an antenna in the cover and a mounting assembly (andand) to mount the one end onto the enclosure via the hole. The mounting assembly includes a flange () which abuts against or is proximate the wall of the enclosure around the hole when the cover is arranged in the hole at a mounted position. The mount also includes a retainer () which engages the opposite end of the cover to close the opening and retain the antenna in the cover. The mounting assembly can be a snap-in mounting assembly or a screw-on mounting assembly.

Panel wiring apparatus

An optical waveguide sheetis fastened to an inward facing access doorof the load center. When the door is closed, the optical waveguide sheet is positioned so that one portion is juxtaposed with the circuit breakerA in the load center, to enable the optical waveguide sheet to receive an optical signalA characterizing current in the circuit breaker. The optical waveguide sheetis further positioned so that another portion is juxtaposed with an optical windowof an aggregator. The optical waveguide sheet is configured to internally reflect the optical signalA within its body and to conduct the internally reflected optical signal from the circuit breaker to the optical window of the aggregator. The aggregator may provide information characterizing current usage to an alarm, a measurement device, the smart grid, or a storage device for later use.

A system for detecting faults in an electric vehicle charging system includes an electric vehicle supply equipment (EVSE) coupled to an electric vehicle via a cable. The EVSE includes a first charging circuit interrupting device (CCID) configured to detect faults at let-go levels between an ungrounded conductor in the cable and an external (or unintended) ground. The first CCID is also configured to detect faults above leakage current levels between a chassis of the vehicle and a power storage device of the vehicle. A second CCID is included in the cable or the vehicle to detect faults at let-go levels between an ungrounded conductor in the cable and the chassis. The system maintains grounding continuity between the electric vehicle and ground. The system thus provides protection at let-go levels while allowing a leakage current in the vehicle to be detected at a higher level for nuisance trip avoidance.

A touch safe system is provided for an electrical panel, such as a panel board or residential load center. The system includes a phase barrier to isolate branch connectors along a center portion of the electrical panel, a top central cover that snaps onto the phase barrier and two side bus covers. The side bus covers are arranged along opposite sides of the phase barrier over opposite side portions of the electrical panel. The system further includes snap-in filler plates to cover any exposed portion of a branch connector which is unoccupied by a circuit breaker. Each of the snap-in filler plates is secured between the top center bus cover and one of the side bus covers. A snap-in lug cover can also be provided for each circuit breaker on the panel, and secured between one of the side bus covers and a recessed portion of the circuit breaker.

Method and apparatus for minimizing exposure to live parts in the panelboard allow safe insertion and removal of a circuit breaker from the panelboard. The method and apparatus provide a shutter assembly that automatically closes off access to conductors in the panelboard until a circuit breaker is inserted in the panelboard. Inserting the circuit breaker in the panelboard causes the shutter assembly to open and allow the circuit breaker to contact the conductors. When the circuit breaker is removed from the panelboard, access to the conductors is automatically closed off again. Such a shutter assembly allows operators to safely insert and remove a circuit breaker and other electrical device from the panelboard.

Methods and systems for minimizing exposure to live parts in a panelboard allow safe insulation and removal of a circuit breaker or other electrical devices from the panelboard. The methods and systems provide an isolation assembly for the panelboard that isolates and prevents contact with energized portions of the circuit breaker as well as the conductors in the panelboard. The isolation assembly covers up the energized part of the circuit breaker, including the line terminal extending from the circuit breaker, and any accessible portion of the conductors in the panelboard. Additionally, for bolt-on type circuit breakers, the isolation assembly replaces the bolts or screws typically used to fasten the line terminals to the conductors in the panelboard with standoff screws that insulate metal screwdrivers and similar tools from the energized part of the circuit breaker.

A load center featuring a two-piece dielectric barrier that securely retains a plug-on neutral rail and methods of assembling the same. The barrier includes a shield and a base having a protrusion that cooperates with fingers of the shield to securely retain the conductor in the load center. The shield is installed over the base and rests on hooks protruding from the base. This creates a distance between the protrusion and the fingers to allow the conductor to be inserted through a gap between the fingers along the conductor's skinny edge. The conductor rotates 90 degrees until it rests on the protrusion. The base and shield are snapped together, causing the hooks of the base to attach to the shield. At the same time, the fingers of the base move downward to rest against the conductor so that it is sandwiched securely between the protrusion and the fingers.

Rotary switch interlock mechanisms and electrical switch assemblies with a rotary switch interlock mechanism are presented herein. An electrical distribution device with at least two electrical switches is disclosed. Each of the electrical switches has a switch actuator that is movable between engaged and disengaged positions. A rotary interlock member is rotatably mounted to the housing of the electrical distribution device adjacent the first and second electrical switches. The rotary interlock member is rotatable 180 degrees between a first orientation, whereat the rotary member allows the switch actuator of the second electrical switch into its engaged position while preventing the switch actuator of the first electrical switch from being moved into its engaged position, and a second orientation, whereat the rotary member allows the first switch actuator to be moved into its engaged position while preventing the second switch actuator from being moved into its engaged position.

A combiner that calculates energy produced by each panel feed during the daytime, and calculates a resistance value needed to calculate the energy by injecting a known current into each panel feed at nighttime and measuring the resulting voltage across a resistive element in each panel feed. A voltage tap across the protection device in each panel feed allows logic and control circuitry to measure the voltage across each protection device. At nighttime, a known current is injected into each panel feed and the voltage across each protection device is measured. Plugging the current and voltage into Ohm's Law, a resistance of each protection device is calculated, then that resistance value is used during the daytime to calculate energy produced by each string in real time and to monitor each string's performance. When an individual string's performance wanes, an alarm is indicated to help the operator troubleshoot which individual panel(s) within the string is responsible for that string's underperformance.

Electrical load spreading arrangements reduce peak power demand. An enclosure houses an electronic circuit board, which receives at a first input terminal a first thermostat control signal from a thermostat intended to control a first air conditioning unit and at a second input terminal a second thermostat control signal from a thermostat intended to control a second AC unit. A controller on the circuit board is programmed with instructions stored in a memory coupled to the controller causing the controller to monitor the first and second input terminals to determine the timing and duration of the thermostat control signals passed to the output terminals for activating or deactivating the AC units such that overlapping operation of the AC units is reduced particularly during peak demand periods. A similar arrangement may be applied to a broader class of HVAC equipment, including water heaters, for example.

A load center is equipped with a neutral phase conductive rail with breaker mounting and retention features providing automatic neutral connection for a plug-on mounted AFI and/or GFI circuit breaker. Breakers may be designed to have specific interfaces to the breaker mounting and retention features of the load center rails. The neutral rail may have two pieces including a breaker undercut positioning rail shorted to a standard neutral rail, or a neutral rail may be designed to have all mounting features integrated therewith. The new panel is compatible with non-AFI and non-GFI breakers.
