Eaton Specification Sheet - 1NK400
The 1NK400 is a purpose-built neutral accessory for Eaton Pow-R-Xpress panelboards. Its robust design delivers a clean single-point neutral path for high ampacity installations, reducing termination complexity and the risk of miswiring. This translates to safer, more reliable distribution and faster commissioning in busy electrical rooms. With a length of twenty two inches, a height of six inches, a width of ten inches, and a weight of six pounds, the unit integrates alongside standard components and aligns with common mounting footprints on four hundred amp panelboards. Special features PRL1X/2X and PRL1A/2A extend compatibility across the Pow-R-Xpress family, simplifying retrofits and phased upgrades. Availability of documentation including the Pow-R-Xpress quick selector reference guides and a dedicated specification sheet helps engineers plan, size wire, and verify connections before site work. Some customers worry about space or clearance; the 1NK400 is designed to fit standard panel enclosures and aligns with other Eaton accessories, reducing the need for custom brackets. In practice, using the 1NK400 reduces commissioning time, lowers the chance of neutral misrouting, and improves maintenance predictability for lighting and emergency systems.
