The primary function of a bussed trough is to enable efficient power distribution throughout a facility. By housing busbars within a protective enclosure, the trough ensures the safe transmission of high electrical currents from the main power source to the load centers.
Electrical Enclosure Guide for Non-Hazardous Locations
There are standards used to categorize electrical enclosures. In the USA, the two bodies that publishes these classes of enclosures are NEMA and UL.
Electrical Enclosures – About, Types and Ratings
About: Electrical Enclosures are a core safety features of a robust electrical system. They have a two-pronged purpose of not only protecting users from live parts of an electrical system but are also designed to protect electrical wiring and /or equipment from harsh environments, related to severe weather conditions or industrial hazards. Enclosures are box-shaped […]
CT Cabinets – About, Types, Ratings
About: Electric meters, depending on the size of electricity (amperage) being measured, can be either transformer rated or self driven. For amperage lower than 200 amperes, self driven meters are generally used where the electricity being consumed passes through the meter. For higher amperages, current transformers or CTs are used coupled with a meter to measure […]
NEMA Type 3R Electrical Enclosure Standards
The NEMA Type 3R electrical enclosure is designed with the same level of protection as the NEMA Type 3 with one exception. The Type 3R comes with the addition of ventilation louvers. The NEMA type 3R has the same level of protection for personnel, as well as protection against falling dirt, water, rain, sleet and […]
