400A Track Busway Splitters & Higher-Capacity Layout Planning
400A Track Busway splitter assemblies can support project-specific overhead power layouts where distribution needs to branch, divide into coordinated downstream paths, or support separately protected sections.
For larger projects, multiple coordinated splitter assemblies may be used across a layout to support higher-capacity distribution discussions such as 800A or 1200A project planning. These should be presented as layout strategies, not as single standalone 800A or 1200A splitter products.
What a 400A Splitter Assembly Does
400A splitter assemblies can support project-specific Track Busway layouts where power needs to be divided into coordinated downstream paths, branches, or separately protected sections. A 400A splitter helps organize how power is routed through the overhead busway layout, while downstream section ratings, conductor configuration, overcurrent protection, voltage drop, access, and code review still govern the design.
Planning Protected Downstream Paths
A 400A splitter assembly helps divide power into coordinated downstream paths where the electrical design requires separate load zones, branches, or protected sections. Each downstream path should be planned around its rating, conductor configuration, overcurrent protection, voltage drop, access requirements, and project-specific electrical review.
This allows larger project layouts to be planned intelligently without treating one continuous busway run as if it has unlimited capacity.
Caption: Example only. Multiple splitter assemblies require project-specific layout review, source coordination, overcurrent protection, and code review.
Using Multiple 400A Splitter Assemblies Across a Layout
Larger layouts may use multiple coordinated 400A splitter assemblies across a project to separate load zones, divide distribution paths, or support phased capacity planning. These assemblies should be placed only where the electrical design intentionally defines protected sections or separately coordinated runs.

800A Project Distribution Layouts
An 800A project distribution discussion may involve multiple 400A splitter assemblies, multiple feed points, separately protected sections, or multiple coordinated busway runs. The 800A figure should describe total project distribution planning, not a single 800A splitter product.
1200A Project Distribution Planning
A 1200A project distribution layout should be positioned as system architecture. It may involve several coordinated 400A splitter assemblies, multiple runs, switchgear or panel coordination, load-zone separation, and separately protected sections. Do not describe this as one standalone 1200A splitter.

Breaker-Protected Feeds, Branches, and Divided Sections
Breaker-protected feed units can be part of a coordinated layout where local overcurrent protection is required at a feed, branch, or divided section. Final feed placement, splitter placement, conductor configuration, breaker sizing, and tap-rule application must be reviewed for the specific project.
Request a Splitter-Based Layout Review
Splitter-based layouts should be reviewed around the project’s equipment layout, source locations, voltage, phase, load calculations, overcurrent protection, conductor configuration, access requirements, and future expansion plans.
