FAQ’s
Busway systems
Busway systems are modular power distribution solutions that use enclosed busbars instead of traditional conduit and cable, offering greater flexibility, scalability, and efficiency—especially in high-power environments like data centers. When paired with tap boxes, they enable safe, fast, and customizable power connections, making them ideal for facilities with evolving electrical needs.
What is a busway system and how does it differ from traditional cable or conduit systems?
A busway (or busduct) system is a modular electrical power distribution solution consisting of an enclosed metal housing with copper or aluminum busbars. It replaces conventional conduit-and-cable systems, offering higher flexibility, faster installation, and easier scalability. Busways are ideal for high-power applications in data centers, manufacturing facilities, and commercial buildings due to their clean layout, reduced installation labor, and ability to handle high amperage efficiently.
What is a tap box in a busway system?
A tap box (or tap-off unit) is a device that connects to a busway to draw power for a downstream load—such as a PDU, panelboard, or individual circuit. It is mounted onto the busway and contains circuit protection (e.g., fuses or breakers) and termination points. Tap boxes enable flexible and modular power distribution by allowing new loads to be added without rewiring the entire system.
What are the advantages of using a busway system with tap boxes in a data center?
Busway systems with tap boxes offer:
- Modularity: Easily add or move power connections.
- Speed: Faster installation than conduit/cable systems.
- Scalability: Supports phased growth in high-density environments.
- Efficiency: Lower voltage drop and cleaner routing.
- Safety: Factory-tested components and accessible power distribution with clear isolation points.
This makes them ideal for modern data centers with evolving power needs.
How do I size or select the right tap box for my application?
Tap box selection depends on factors such as:
- Busway system voltage and amperage
- Load requirements
- Number of poles/phases
- Circuit protection needs (e.g., breaker size/type)
- Mounting location (top, bottom, inline)
Working with an experienced electrical engineer or manufacturer like Power Quest is key to ensuring code compliance (e.g., NEC 368) and safe operation.
Are busway systems UL listed or NEC compliant?
Yes, most major busway systems are UL 857 listed (for busways) and must comply with NEC Article 368, which governs their use in commercial and industrial buildings. Tap boxes may also fall under UL 508A (if customized or used in control panel applications).
Power Quest always ensure that components are tested and approved for the intended environment, including ratings for indoor/outdoor use and temperature rise.
