The growing demand for cost efficiency, enhanced safety, and reliability in power distribution systems has propelled the demand for busbar trunking systems in the utility sector. The electric distribution system is prefabricated and consists of a set of copper or aluminum bus bars suitably enclosed with superb protection against any foreign materials. Busbar trunking systems have emerged as highly efficient, safe, and ideal electric supply and distribution system suitable for a variety of industrial installations and in high-rise buildings. Enabled by compact design and standard plug-in boxes, these systems can deliver current in the range 125A to 2000A suitable for a wide variety of industrial purposes. They are gaining prominence over normal cabling systems due to a variety of factors.
