Splitter Trough · 600A, 600 VAC, NEMA 1, 72 x 10 x 6 in - EXM 1100 T6604
Steel splitter trough for up to 600A, 600 VAC power distribution in ordinary indoor locations. This EXM 1100 Series unit includes factory-installed insulated splitter blocks, concentric knockouts, and a padlockable door for commercial and industrial service equipment layouts.
What this product is for
This steel splitter trough is used to split and distribute feeder conductors in commercial and industrial electrical systems. It is built for up to 600A, 600 VAC service in ordinary indoor locations where a NEMA 1 enclosure is suitable.
Use for
Use for indoor power distribution, service entrance transitions, feeder taps, and multi-circuit distribution layouts where a splitter trough with factory-installed insulated blocks is required. Commonly used by electricians and contractors in panel rooms, electrical rooms, and service distribution areas.
Avoid for
Avoid using this trough in wet locations, washdown areas, or outdoor installations unless the installation is otherwise protected and code-compliant. NEMA 1 and IP30 construction is intended for ordinary indoor locations only.
Best for
Best for contractors needing a 600A indoor splitter trough with lay-in lug access, concentric knockouts on all sides, and a straightforward wall or panel mounting format. It suits projects where serviceability and conductor routing matter.
Installed in
Typically installed in commercial buildings, industrial facilities, service rooms, utility areas, and other indoor electrical distribution spaces. The enclosure measures 72 x 10 x 6 in (approximately 1829 x 254 x 152 mm).
Why this product exists
This product provides a practical way to divide incoming power to multiple downstream circuits while keeping conductors enclosed and accessible. Factory-installed insulated splitter blocks and removable lug tops help reduce field assembly time and simplify conductor placement.
Compared with similar products
Compared with smaller splitter troughs, this 600A model is intended for higher-capacity feeder distribution. Compared with outdoor or gasketed enclosures, this NEMA 1 steel trough is intended for indoor use where environmental sealing is not required.
