450A Track Busway Splitters for T225 Split-Run Layouts

A 450A splitter is rated for a 450A supply and splits that supply into two 225A sources for a split run of T225 Track Busway. For larger layouts, multiple 450A splitters can be coordinated across the project to create 900A or 1800A distribution strategies using multiple protected 225A T225 sources.

900A and 1800A layouts are built from multiple 450A splitters and multiple 225A T225 sources.

How Splitters Are Used

A 450A splitter supplies a split T225 Track Busway run by dividing one 450A supply into two 225A T225 sources. These two 225A sources can feed separate directions, sections, zones, or run segments within the approved project layout.

Step 1

Incoming Feed

A 450A supply is brought to the splitter location from the project’s approved power source.

Step 2

450A Splitter

The 450A splitter divides the incoming supply into two 225A T225 sources for a split run.

Step 3

Two 225A T225 Sources

Each outgoing 225A source is coordinated as part of the project’s approved T225 layout.

Step 4

Split T225 Track Busway Run

The downstream T225 sections are planned around the two 225A sources supplied from the 450A splitter.

Coordinating a 450A Splitter with Two 225A T225 Sources

A single 450A splitter supplies two 225A T225 sources for a split run. For larger projects, two 450A splitters can support a 900A layout, and four 450A splitters can support an 1800A layout, with each splitter feeding two 225A T225 sources.

Multiple 225A Track Busway runs with line feeds, joiner kits, and power drops for larger project distribution layouts.

Using Multiple 450A Splitters Across a Larger T225 Layout

Larger layouts may use multiple coordinated 450A splitters to separate load zones, divide T225 distribution paths, support phased capacity planning, or determine how often power should be supplied to the busway. Two 450A splitters create a 900A layout, while four 450A splitters create an 1800A layout using eight total 225A T225 sources.

Breaker-Protected Feeds and Splitter Breakers

Breaker protection is available for feed units and can also be included as part of splitter assemblies where the project requires local overcurrent protection. This can apply to feeds, branches, divided sections, or downstream sources based on the approved electrical layout.

Final breaker placement, feed placement, splitter placement, conductor configuration, breaker sizing, and tap-rule application are confirmed during project-specific electrical review.

Planning 900A and 1800A T225 Splitter Layouts

900A T225 Splitter Layouts

A 900A T225 splitter layout uses two 450A splitters. Each 450A splitter supplies two 225A T225 sources, creating four total 225A T225 sources across the layout.
1800A T225 Splitter Layouts

An 1800A T225 splitter layout uses four 450A splitters. Each splitter supplies two 225A T225 sources, creating eight total 225A T225 sources across larger project layouts with multiple feed points, zones, or split runs.
