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 vertical support provides for the rapid assembly, disassembly, and modification of a shelving system in a variety of configurations, as determined by the practical and aesthetic requirements of the user. The vertical support facilitates the mounting of a variety of attachment members, such as shelves, hangers, or media boards, that contain powered appliances, allowing the user to further customize the shelving system to his practical and aesthetic requirements. The vertical support makes it easy for a user to mount these attachment members and hides the connections of the various components, to maximize the aesthetic appeal of the shelving display. Additionally, vertical support can be configured with other subcomponents to form shelving systems.

A modular, space-efficient support structure mounts multiple electrical devices. The structure is modular to allow for subsequent addition and removal of electrical devices by adding and removing primary structural elements coupled for structural efficiency. The structure is deployable in many locations without reconfiguration and has reduced dependence on local site conditions. The structure uses non-permanent construction methods to facilitate rapid assembly, disassembly, re-deployment and re-use of components. Multiple electrical devices such as transformers are mounted at elevation on device mounting columns. The electrical devices are interconnected to each other in parallel or series with connectors mounted on the top portion of the device to allow maintenance clearance underneath. The arrangement of the electrical devices maximizes the density of the devices while maintaining vertical, lateral and radial safety clearances. The electrical devices are arranged in a symmetrical fashion around the primary structural element for symmetrical load distribution.

A support rail and housing assembly is mountable on a housing base. The housings are equipped with electrical contact and/or functional elements which can be strung together. The support rail is mountable on the mounting base even when the housings have already been arranged on the support rail before the support rail is mounted. The support rail is secured to the mounting base by two or more mounting pins which have been placed before the support rail is mounted to the mounting base. The mounting pins and the support rail are designed to correspond to each other such that the support rail can be placed on the mounting pins and locked thereto without using a tool.

A termination field and a guide member are independently pivotally coupled to a base body. The termination field pivots relative to the base body along a path of travel. The guide member is coupled to the base body to provide bend radius protection to cables plugged into the termination field. The guide member defines a channel leading the cables from the termination field towards a first side of the base body at an exterior of the base body. In certain examples, the guide member and termination field pivot relative to the base body about different hinge axes. In other examples, the termination field pivots with the guide member for part of the path of travel and relative to the guide member for another part of the path of travel.

A circuit breaker arrangement includes a housing, a contact seated in the housing, and a lead in electrical communication with the at least one contact and disposed outside the housing. The circuit breaker arrangement includes a heat sink in thermal communication with the lead to transfer heat between the contact and the lead.
