Bus Duct

Definition

A bus duct is a prefabricated unit containing one or more electric conductors, often a metal bar, that serves as a common connection for two or more circuits.

Purpose

Bus ducts are used to distribute electrical power efficiently and safely within industrial, commercial, and large residential buildings. They provide a flexible and modular method for routing electrical power, facilitating easier installation, maintenance, and future expansion compared to traditional wiring methods.

Examples of Use

1. Industrial Facilities: Distributing power to various machinery and equipment across a manufacturing floor.
2. Commercial Buildings: Routing power through large office buildings, shopping centers, or hospitals.
3. Data Centers: Providing reliable power distribution to servers and IT infrastructure.

Related Terms

• Busbar: A metallic strip or bar used for power distribution within a bus duct.
• Electrical Conduit: A tube used to protect and route electrical wiring.
• Switchgear: A combination of electrical disconnects, fuses, or circuit breakers used to control, protect, and isolate electrical equipment.

Notes

Bus ducts are preferred in scenarios where high current loads are present due to their ability to carry large currents efficiently and their robustness against mechanical damage. Proper installation and regular inspections are critical to ensure safety and reliability.
