An antenna platform includes: a mounting assembly configured to mount to an antenna tower; a plurality of main floor sections, each of the main floor sections connected to the mounting assembly; a plurality of auxiliary floor sections, the auxiliary floor sections arranged in alternating relationship with the plurality of main floor sections to form an endless platform, each auxiliary floor section mounted to two adjacent main floor sections; a plurality of pole supports mounted to each main floor section; a plurality of horizontal antenna poles mounted to the plurality of pole supports, wherein some of the plurality of horizontal antenna poles are main horizontal antenna poles that are positioned radially outwardly of each main floor section, and wherein others of the plurality of horizontal antenna poles are auxiliary horizontal antenna poles that are positioned radially outwardly of each auxiliary floor section; and a plurality of vertical antenna poles mounted to the horizontal antenna poles.

A junction box architecture includes a main circuit breaker, plurality of branch circuit breakers, and an arc detection unit. The main circuit breaker input is connected to main power supply lines, e.g., phase 1 and phase 2 power lines. The main circuit breaker output is connected to respective inputs of branch circuit breakers and to an input of the arc detection unit. The arc detection unit includes an enable output and is configured to generate an enable signal on the enable output. The enable output is coupled to enable inputs of each branch circuit breaker. When no enable signal is present on an enable input of any one branch circuit breaker, the one breaker will not trip. In general, for any one circuit breaker to trip, the breaker must simultaneously detect a high frequency current in the associated branch circuit and receive an enable signal from the arc detection unit.

Method and apparatus for circuit breaking

A fully automated circuit breaker saddle assembly in the form of a plastic support base having modular components that define the end and central sections of the support base. The components are snappingly fitted together and are retained by means of formations on the ends of the respective components. The metal circuit breaker stab assemblies are attached to the base by connectors integrally-formed in the base.

Low voltage electric switchgear equipment includes a central processor unit electrically interconnected with electronic main and branch circuit interrupters within the same enclosure and used within a multi-phase power distribution circuit. A terminal connector block is connected by cable with each of the electronic trip units within the branch circuit interrupters to provide communications between the branch circuit interrupters and the main circuit interrupter for continuously updating the status of the branch circuit interrupters and their associated electrical equipment. Strain relief is provided to the cable connecting between the terminal connector block and the branch circuit interrupter to prevent damage to the electrical components within the electronic trip unit that are internally connected with the cable.

Electronic circuit interrupter with attached terminal connector block

A compact circuit breaker containing an electronic trip unit employs an actuator-accessory unit to articulate the circuit breaker operating mechanism and separate the circuit breaker contacts to interrupt current within a protected circuit. A tolerance compensating spring is attached to the actuator-accessory unit trip armature to precisely set the separation gap between the tip of the armature and the actuator-accessory trip actuator arm.
