Construction Specification For Electrical Busbar Trunking (Bus Duct) System

Sample MEP Specification For Electrical Busbar Trunking

Busbar Trunking System (BBT) in electrical construction, uses to transporting electrical power to a shorter distance but many utilization point, say, within the building or a compound of facilities. Though cables can also be used in these areas, their economic impact would be high if compared to the effective Busbar Trunking System. It will help us to tap power directly from where we want it to be and make utilize to the service point.
