Eaton PowerWave* 2 vs. USA TrackBusway®
Both USA TrackBusway® T225 and Eaton PowerWave 2 use open-channel designs that let tap-off units be added or repositioned as layouts change.
The compared system offers busway ratings from 250A to 1000A. USA TrackBusway® uses additional feeds to electrically isolated 225A sections, with splitters and feed placement planned around project loads. Each section retains its 225A-per-phase rating.
T225 is manufactured by USA TrackBusway® and combines 225A-per-phase busway lengths, feeds, joiners, and repositionable tap-offs in a modular system. The typical production lead time for a complete 225A system including tap-offs is 8 weeks, with factory-direct layout assistance and BIM support.

Need More Than 225A per Phase?
A CLOSER LOOK AT T225 SPLITTER LAYOUTS
A facility’s total demand can exceed 225A per phase while its loads are served by electrically separate, protected T225 sections. A 450A splitter serves two 225A feed circuits. Circuits sharing a splitter share its upstream supply and do not establish independent A/B power paths.
Each T225 section is limited to 225A per phase, per feed, with tap-offs up to 60A per phase. If a load exceeds either limit, the design needs a different distribution arrangement or appropriately rated equipment. Confirm normal and required outage loads, upstream capacity, protection and monitoring for the complete layout.

Need help choosing the right busway system?
USA TrackBusway provides complimentary design drawings and installation guidance to help you select and configure the right Track Busway solution.
Compare Capacity, Layout and Project Support
In higher-capacity data-center projects, the busway decision often centers on feeder strategy, monitoring requirements, release coordination, and how much capacity should be concentrated into each busway run.
USA TrackBusway manufactures the open-channel 225A system, rated at 225A per phase. Factory-direct layout support, complimentary drawings, and BIM resources help plan feeds and separate supply zones around actual load locations.
Key Advantages of USA TrackBusway
Factory-direct layout support for distributed-feed busway projects
USA TrackBusway works directly with engineers, contractors, and facility teams to review load locations, feed placement, available capacity, lead time, and future layout changes. This helps determine whether separately planned and protected T225 runs or electrically separate sections can support the project.
Complimentary drawings, BIM resources, and project-specific layout support can help clarify where power is needed before the system is released. For projects comparing higher-ampacity data-center busway with a distributed-feed Track Busway approach, this support can make it easier to evaluate cost, schedule, and layout flexibility.
Shared Busway Capabilities
Both PowerWave 2 and USA TrackBusway can support overhead busway distribution for projects that need flexible power access above equipment or work areas.
- Voltage Capabilities Both product families offer configurations rated up to 600V. Confirm the marked voltage and conductor arrangement of the selected components.
- Installation Compare contractor installation estimates for the same layout, connection count and site conditions.
Side-by-Side System Comparison
The right busway strategy depends on required ampacity, tap-off load size, monitoring scope, lead time, and whether power needs to be concentrated in dense rack areas or distributed over an area.

Frequently Asked Questions About Track Busway
Plan system capacity, monitoring and voltage around your equipment loads.
For general questions about Track Busway safety, standards, reconfiguration, and installation, visit the full Track Busway FAQ page.
When is a higher-ampacity data-center busway the better fit?
Consider a higher-ampacity system when a load requires:
- More than 225A per phase through one T225 length
- More than 60A per phase from one tap-off
A larger total layout may instead use separately fed, electrically separate, protected sections. Check calculated normal and required outage loads against the selected assemblies, feeds and protection.
When is USA TrackBusway T225 the better fit?
T225 can serve data-center rack rows, server rooms, workcells, laboratories and other equipment zones. Calculated normal and required outage loads must fit:
- 225A per phase, per feed and busway section
- Up to 60A per phase for each tap-off
- The selected equipment’s limits
Plan separately fed, electrically separate sections near the loads. Coordinate upstream capacity and protection.
How should critical power monitoring be evaluated?
Both systems offer monitoring. Match the selected hardware to the required measurement points, alarms, communications and integration.
- T225: Schneider-based metering is a regular feed option and is available at selected tap-offs. A project-specific two-cord PowerDrop can measure each cord output separately.
- End-feed and tap-off monitoring are also available for the compared system.
For T225, a local meter display, optional HMI or networked web interface depends on the selected hardware.
Can both approaches support power distribution up to 600V?
Both families offer configurations rated up to 600V.
- Choose the voltage and conductor arrangement required by the load.
- Verify every selected component’s ratings and listing.
- Also compare ampacity, tap-off loads, monitoring and schedule.
