A modular switchboard provides an adjustable length bus bridge for electrically connecting two adjacent switchboards, where the length of the bus bridge can be adjusted on site if needed. The bus bridge comprises a first set of busbars, each being electrically insulated from one another, and a second set of busbars, each being electrically insulated from one another. The first and second sets of busbars are arranged such that the busbars in the first set of busbars and the busbars in the second set of busbars are slidable relative to one another to adjust a length of the bus bridge. A longitudinal slot is formed in each busbar in either the first or the second set of busbars, or both, to accommodate a through bolt in the bus bridge when the first and second set of busbars slide relative to one another.

The present invention discloses a field assembled electrical distribution device assembled from various prepackaged modular kits. The prepackaged modular kits include all of the components required for their assembly. The prepackaged modular kits, when assembled by a certified assembler using a certified method and verification means provided by the modular kit manufacturer and one or more well know third-party certifiers, meets the requirements local, national and international electrical codes and is eligible for the third-party's certification mark.

A plug-on neutral (PON) device includes a housing that defines a phase cooperation portion configured to physically cooperate with phase buses of a bus assembly. The phase cooperation portion is configured to be electrically isolated from the phase buses and stabilize the PON device when installed on the bus assembly. A neutral cooperation portion is configured to physically cooperate with the neutral bus and to physically stabilize the PON device when installed. An electrical connector disposed at the neutral cooperation portion is configured to electrically connect to the neutral bus at an external end and to electrically connect to a conductive current path at its internal end. A lug assembly has one or more conductive terminal lugs, each terminal lug configured to receive current from an external neutral source via an aperture in the lug end of the housing and to electrically connect to the current path.

Plug-on neutral device and kit

A service-entrance plug-on neutral (SEPON) device having a conductive neutral sled having a line sled side and a load sled side configured to electrically couple with a neutral bus of a bus assembly of a switchboard or panelboard when the SEPON device is installed on the bus assembly; a lug assembly having one or more electrically conductive terminal lugs configured to receive line neutral current from an external source and to electrically couple to the line sled side; a movable neutral disconnect link movable into a connection position to establish electrical continuity between the line sled side and the load sled side and into a disconnection position to cause a discontinuity between the line sled side and the load sled side; and a main bonding jumper having first mounted to the line sled side and a second ends configured to be moved between a non-connected position and a ground position.

A closed door operation racking device is provided for racking a circuit breaker to and from a power bus from outside of a housing of a motor control center unit. The racking device includes a racking operator assembly and a push-button interlock assembly. The racking operator is configured to rack-in the electrical device and connect the stabs to a power bus in a connected position and to rack-out the electrical device and disconnect the stabs from the power bus in a disconnected position. The push-button interlock assembly prevents the operation of the racking operator under certain conditions, and includes a spring-loaded locker assembly and a spring-loaded push-button operator assembly. A push-button operator of the push-button operator assembly is depressed to disengage the locker assembly from the racking operator to allow operation of the racking operator.

A circuit breaker may be plugged into a breaker compartment in a panelboard without making a connection to a power bus of the panel board. A tool may be inserted into the breaker compartment to operate movable contacts that connect, or disconnect, the circuit breaker from the power bus without de-energizing the power line network. Inserting the tool into the breaker compartment first causes a trip actuator to trip the circuit breaker.

A retractable connector assembly for establishing an electrical connection to a power bus bar from an electrical device is disclosed. The retractable connector assembly includes a frame plate and a sled. The sled has a rack and a connector assembly having an electrical contact. The sled has an extended position and a retracted position relative to the frame plate. A spur gear is mounted on the frame plate. The spur gear engages the rack to move the sled between the retracted position and the extended position when the spur gear is rotated. The electrical contact creates an electrical connection with the power bus bar when the sled is in the extended position but not in the retracted position. Safety interlocks and indicia can be provided for the connector assembly.

A busway joint pack includes a first latch mechanism having an open position and a closed position and a second latch mechanism having an open position and a closed position. The busway joint pack further includes a first connector plate having a first major surface opposing a second major surface and a second connector plate having a first major surface opposing a second major surface. The second connector plate is spaced from the first connector plate such that the first and the second connector plates are configured to engage phase conductors of busway sections in a clamping fashion when to the first latch mechanism is in the closed position and the second latch mechanism is in the closed position. The busway joint pack lacks a fastener positioned through the center of the first and the second connector plates, but is rather held together by the latch mechanisms.

An electrical busway plug-in unit includes a pair of restraint mechanisms extending through the housing of the plug-in unit for mechanically attaching the plug-in unit to the busway. Each restraint mechanism includes a rotatable shaft extending through the front wall of the housing, and a knob attached to the front end of the shaft, on the exterior side of the front wall of the housing, for manually rotating the shaft. A mechanical connector projects rearwardly from the rear wall of the housing and extends forwardly into the interior of the housing where the connector is coupled to the shaft so that rotational movement of the shaft in opposite directions moves the connector into and out of latching engagement with the busway.

A panelboard supplies electricity to multiple loads, such as lighting fixtures and/or other electrical devices via one or more high-amperage circuit breakers and one or more low-amperage circuit breakers. The panelboard includes one or more vertical busbars and one or more horizontal busbars coupled together in a single housing. The one or more horizontal busbars are coupled to a main input breaker that receives electricity from a source. The main input breaker distributes the electricity to the horizontal busbars. The horizontal busbars distribute the electricity to the high-amperage circuit breakers coupled thereto and to the vertical busbars. The vertical busbars distribute the electricity to the low-amperage circuit breakers coupled thereto.

A busway joint pack for joining busway conductor sections has a heat sink assembly with an interstitial heat sink portion sized to fit between its connector plates; an exterior heat sink portion projecting beyond the exterior surface of a side panel of the joint pack; with the interstitial heat sink portion having thermal conduction to the exterior heat sink portion; to attain cooler operation. The heat sink may include thermally conductive dielectric materials or metals, or both, or other thermally conductive materials used with the thermally conductive dielectric materials.
