  • Does a secondary distribution box need a protective enclosure

    Does a secondary distribution box need a protective enclosure

    These applications usually require a stronger enclosure structure and a suitable IP protection rating. Metal distribution boxes are commonly used in industrial and commercial applications where higher mechanical strength, impact resistance, and long-term durability are required. This document provides specifications, ordering information, illustrations, and application instructions for the various sizes of non-concrete and precast concrete enclosures used in PG&E electric underground secondary distribution. The words boxes/enclosures have the same meaning and are used. At a basic level, electrical panels (also called distribution boards or panelboards) split incoming power into branch circuits and protect each branch with breakers or fuses. Switchgear is a higher-capacity family of equipment—typically used at primary distribution points—that includes switching. Discover the robust selection of secondary pedestals at Hubbell, designed to enhance and secure your power distribution needs.
