摘要: A compact auxiliary connector can include two bushings each with an electrical connector(s), and a tubing connected between the two bushings to insulate an electrical cable, which is connected between electrical connectors of the two bushings. The electrical connector of each of the two bushings can be connected to an electrical device, a line or load bus or a combination thereof, according to the desired connection configuration. Each bushing may also include a flexible joint cover, such as a boot, to cover the connection of the bushing connectors to a bus, such as a primary bus. The compact auxiliary connector can manage live connections between auxiliary or other device(s) and line/load buses in a switchgear cabinet of a switchgear assembly. The bushings, tubing and flexible joint cover can be formed of insulating materials having desired dielectric strength according to the voltage applications.

摘要: An apparatus provides homeowner selectable full or partial back-up power of a residential photovoltaic system to power critical loads during a utility power outage. A single split-bus electrical panel with a first panel section supplies utility power to non-critical loads and a second panel section supplies photovoltaic power to critical loads. A mechanical interlock in contact with interlocked circuit breakers of the first panel, prevents them from both being simultaneously on. A patch panel associated with the split-bus electrical panel enables an installer to selectively connect factory installed connections to either: connect the second panel section to utility power via a microgrid interconnection device when the second panel section is at least partially powered by back-up photovoltaic power, or connect the first panel section through one of the interlocked circuit breakers to utility power via the microgrid interconnection device to provide both panel sections with full back-up photovoltaic power.

摘要: A modular retainer assembly (10) is presented herein. The modular retainer assembly (10), includes a first retainer module (12a) defining a flexible first retaining finger (14a) and a second retainer module (12b) that is distinct from and joined to the first retaining module (12a). The second retainer module (12b) defines a flexible second retaining finger (14b). When the first and second retainer modules (12a, 12b) are mated together, the first retaining finger (14a) is arranged opposite the second retaining finger (14b). The first and second retaining fingers (14a, 14b) are configured to receive and retain an elongate article (20), such as a wire cable, between them.
