FAQs
The PRL1X1400B42C is an interior panelboard designed for 120/240V single-phase service with 1P 3W configuration. Plan for a suitable mounting surface, adequate ventilation, and clearance for door access and wiring access at the bus bars. Ensure proper feeder routing to the 42 copper circuit spaces and verify UL 67 compliance during commissioning. Budget for 72 inch depth and 8 inch width to fit within the targeted enclosure footprint.
The PRL1X1400B42C aligns with Eaton’s Pow-R-Xpress stocking program by providing a standardized interior panelboard design with defined circuit count and protection (MCB & SFB). This enables faster procurement, consistent spare parts, and simplified field replacements, reducing downtime and streamlining project schedules for panel installations in facilities and control rooms.
This panelboard is well-suited for commercial electrical rooms, light industrial environments, and machine control panels that require reliable 120/240V distribution with a high circuit density. It supports 400A input and copper bus for low voltage drop, making it appropriate for facilities seeking compact, scalable power distribution with robust protection and code compliance.
Yes. The PRL1X1400B42C is UL 67 listed, indicating conformity with recognized safety standards for panelboards. Its copper bus design and interior construction are selected to withstand typical industrial and commercial duty cycles, helping ensure safe operation, easier code compliance, and reliable performance across expected service conditions.
Total cost of ownership is reduced by the 400A rating and dense 42 circuit capacity, which minimize enclosure footprint and downstream expansion costs. Copper bus bars offer durable, low-resistance pathways, reducing wear on protective devices. Regular inspection of MCBs and SFBs, along with adherence to UL 67 guidelines, supports long-term reliability and predictable maintenance budgets.
