- Frequently Asked Questions
What is dense busway?
Dense (sandwich) busway is a compact busbar system where phase conductors are tightly stacked with thin insulation, giving low impedance and low voltage drop for high-current distribution.
How is busway tapped for loads?
Plug-in tap-off units insert at intervals along the run, allowing loads to be added or moved without de-energizing the main bus.
What current range is typical?
250–6300 A for low-voltage distribution, with higher ratings available for special applications.
