FAQs
Begin with a detailed mounting plan that respects the 68.75 in L, 22 in W, and 8 in H footprint. Verify the top-feed wiring configuration, confirm three-phase connections, then install bus bars and circuit modules per the UL 67 guidelines. Ensure all feeders are correctly terminated, use copper conductors of appropriate gauge, and perform an insulation and clearance check before power-up.
Yes. The PRL4X interior design supports modular subfeed configurations, including business-relevant subs like PD5, PXR20, and ALSI 18CKT units. To ensure compatibility, verify kit part numbers against Eaton’s current Pow-R-Xpress subfeed catalog and follow the manufacturer’s installation diagrams for mounting, interconnection, and protective devices.
This panelboard is UL 67 certified, confirming compliance with established safety and performance standards for interior power distribution equipment. While UL 67 is the primary certification listed, always cross-check any regional regulatory requirements and consult Eaton documentation for additional compliance guidance relevant to your facility.
The interior panelboard measures 68.75 inches in length, 22 inches in width, and 8 inches in height, with a weight of 350 pounds. These dimensions influence enclosure space planning, mounting methods, and service clearances. Plan for adequate access to rear and top-feed connections during installation and maintenance.
Industry applications include manufacturing plants, data centers, and process facilities requiring reliable three-phase power distribution at 208/120V. The 1200A rating supports heavy-load circuits, while the copper bus and UL 67 certification deliver low impedance and robust safety. The interior design also enables scalable upgrades and modular expansion with minimal downtime.
