FAQs
The 6672 GRT uses embossed thru holes that align with standard Eaton B-Line enclosure mounting patterns, enabling straightforward installation on compatible panels. Secure the trough with plated screws in the flange, then route conductors through embossed holes for a neat, repeatable cabling route. This approach minimizes field drilling and ensures reliable alignment across projects.
With 23 bottom knockouts and a 6 x 6 inch footprint, the trough accommodates large cable bundles and mixed cable diameters without crowding. Its 16-gauge steel construction provides rigidity under load, maintaining channel integrity and thermal performance in busy control rooms and machine centers. This translates to fewer rework incidents and faster commissioning.
Yes. The 6672 GRT is CSA Certified and UL Listed, confirming compliance with North American electrical safety standards. These certifications support regulatory audits, simplify approvals during panel builds, and give procurement teams a reliable, standards-aligned component for critical electrical infrastructure.
Plan knockouts in advance and align the trough with the enclosure’s embossed hole pattern. Secure the cover with flange screws first to prevent movement, then route cables through allotted knockouts before final enclosure closure. Keeping a spare set of common-size knockouts on hand minimizes field adjustments and speeds up commissioning.
Yes, the 6672 GRT carries a NEMA 3R rating and ANSI 61 gray finish, offering protection against rain and dirt for semi-exposed environments. Ensure site conditions stay within enclosure ratings and pair with appropriate sealing if required. For extreme weather, verify additional environmental requirements with site engineering.
