Schneider Electric NQ442L2C Main Lug Panelboard

Schneider Electric's NQ442L2C is a 225 A, 240 V, 3-phase, 4-wire panelboard interior in the NQ family designed for main-lug service with a 42-space copper-bus arrangement and a Type 1 indoor enclosure. The interior accepts copper or aluminum conductors for the lug connections—copper up to AWG 6 and aluminum up to 350 kcmil—providing flexible feeder wiring. It supports plug-on and bolt-on circuit breakers, enabling field configurations from standard distribution layouts up to the required protection. With a short-circuit current rating up to 100 kA, the NQ442L2C is suitable for many commercial and light-industrial services, where a separate upstream main disconnect is used or where a main-lug-only arrangement is desired. This panelboard interior is part of the Square D/NQ line and is designed for indoor Type 1 environments in a 42-pole, 225 A configuration.
