Current Transformer Cabinet Connections

Power distribution electrical enclosures are designed to supply power to electrical equipment, to start or stop the flow of power to electrical equipment and to monitor and detect the operation of electrical equipment. Power distribution cabinets protect the internal components from the surrounding environment and protects operators from electric shock. They come in many different shapes, sizes and materials. The power distribution enclosure will have holes made for pulling cables inside for incoming electric current and cables leaving for power distribution. Having the proper connectors are essential for maintaining the NEMA rating of the enclosure.

Current transformer cabinet connections are used in the process of lowering or stepping down a high current to a lower, safer level for measurement and management. The current transformer cabinet is part of an electrical distribution system and house the current transformers, which are used for metering. Terminal box connections split feeder circuit conductors into multiple branch circuit conductors. Terminal boxes are insulated blocks that secure two or more wires together.

Hoffman Terminal Box Lug Assemblies tap feeder to branch circuits in terminal boxes. Each 400 amp main lug has copper/aluminum connectors secured to insulators.

Hoffman Splitter Box Block Assemblies tap feeder branch circuits in splitter boxes and troughs. Each 600 V block includes a main lug and branch lugs, together with copper/aluminum connectors secured to insulators.

Hoffman Interchangeable Bolt-On-Hubs are used on terminal boxes for easy and secure entry through the top of the enclosure for conduits sized 1 to 2.5 inches.
