Power Distribution Electrical Enclosures

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.

Receptacles (din rail mount) are designed to mount easily to a din rail and provide convenient plug-in surge protected power to an electrical enclosure that contains cord-connected equipment.

Enclosure grounding is an essential safety measure that must be installed in order to clear any electrical faults and to protect equipment from damage and operators from electric shock. Ungrounded or poorly grounded enclosures will not clear the electrical fault and can remain operating and energized. The ground path resistance from the enclosure back to the source ground must be very low, resulting in the fault current traveling quickly to ground.
