A method of assembling a load center featuring a dielectric barrier that securely retains a plug-on neutral rail without requiring any fasteners. The dielectric barrier and the rail are installed in the same Z-axis direction, which is orthogonal to a rear wall of an enclosure into which the load center is installed. Retention features in the dielectric barrier can create a snap-fit connection between the rail and the barrier, or the barrier can feature a support feature onto which the rail snaps as the rail is installed relative to the dielectric barrier in the Z-axis direction. The snap fit connections eliminate the need for any fasteners, and together with the Z-axis assembly, the assembly process is simplified and accelerated and the possibility of assembly error is reduced or eliminated.

A jumper is for an electrical switching apparatus having a plurality of poles. Each of the poles comprises a terminal. The terminal of a first one of the poles is proximate the terminal of a second one of the poles. The jumper includes a jumper member having an attachment portion and a heat sink portion. The attachment portion is structured to electrically connect the terminal of the first one of the poles to the terminal of the second one of the poles. The heat sink portion includes a plurality of spaced apart heat transfer members that are arranged in a plurality of rows and a plurality of columns.

A plug-in summation current transformer module for insertion into a module-overlapping installation space of a multi-pole rail-mounted device that is formed of a plurality of housing modules has a summation current transformer and primary conductors routed through the tubular summation current transformer. The primary conductors have primary conductor ends. A primary conductor holder for fixing the primary conductor ends is fastened to the summation current transformer and adopts a fixing position for holding the primary conductor ends in an assembling position for insertion into a module-overlapping installation space and a releasing position where the primary conductor ends move transversely into a releasing position allowing the primary conductor ends to join into their contacts in the modules.

A configurable electrical distribution panel, comprising: circuit breakers; a panel, for operating on/off switches of the circuit breakers, wherein each circuit breaker has a corresponding EPD (Electronic Paper Display) for displaying information associated with the circuit breaker; and a control circuit, wherein the control circuit can obtain a corresponding amount of current flowing through each circuit breaker via a corresponding current sensor and displaying each obtained amount of current on a corresponding EPD, respectively.

An electrical conductor assembly for use in a power distribution assembly includes an electrical conductor. A casing covers at least a portion of the electrical conductor. The casing insulates the at least a portion of the electrical conductor.

Thermal management structures and techniques are provided for cooling solid-state circuit breakers. For example, a circuit breaker comprises an integrated heat sink which is configured to absorb and dissipate heat from electronic components of the circuit breaker using a combination of conduction and convection.
