FAQs
Yes. The PRL1X3400X42AD is designed to fit within Eaton’s Pow-R-Xpress ecosystem and complements the Pow-R-Line Xpert family for fast commissioning. It supports standard 208/120 V 3P4W service, offers a dense 42-circuit interior, and leverages modular interior components, enabling seamless upgrades without replacing existing sub-feed arrangements. Ensure you verify enclosure dimensions and compatible bus kits during planning.
Key considerations include adequate enclosure space, mounting clearances, and proper wiring methods to handle 400 A service. The unit uses an aluminum bus for weight and durability advantages, so plan for compatible lugs, termination torque, and conductor sizing. The 79 in length and 8.5 in width define a standard footprint that supports predictable labeling and orderly cabling in commercial rooms.
With 42 circuits in a single interior, wiring density improves, reducing the number of enclosures required for a given load. This enables shorter feeder runs and simpler conductor routing. Labeling tasks are streamlined by consistent circuit arrangements and standardized documentation, which lowers commissioning time and minimizes field errors during testing and startup.
The PRL1X3400X42AD carries UL 67 certification for panelboard safety and is NEMA compliant, aligning with common electrical installation standards in commercial and industrial facilities. These certifications help simplify approvals with AHJs, support warranty validity, and reduce project risk by meeting recognized safety benchmarks.
The 400 A, 42-circuit interior panelboard delivers faster installation, reduced space, and scalable future expansion, which translates to lower labor costs and faster time-to-operation. Aluminum bus reduces weight and simplifies handling during installation. Ongoing maintenance is streamlined due to standardized components, clear labeling, and compatibility with Eaton’s quick-reference guides, helping facilities keep downtime to a minimum.
