Busduct System were UL Classified, Fully Type Tested design as per IEC61439-1 and IEC61439-6.

Busduct System performs the function of transporting current from one point to the other traditionally cables were used for this function. Busduct goes beyond what cables do. Busduct System can tap off power to switchgear for further distribution using plug-in unit. In comparison to cables, Busduct thus continues as a single system to replace cable as well as distribution boards at floor level for building (commercial & industrial). Busduct is a system for an effective and efficient supply of electricity borne by valuable resources. In this era where high rise buildings and large scale industrial plants have become a common sight, a busduct system truly meets the needs of the systematic and economical wiring.


All Powerbox Busducts and accessories were designed, manufactured and tested in accordance with the following IEC Standards:
