Abb aqu1424rcxaxb4 Lighting Panelboard Interior 400A 42-circuit

Product Description

The ABB aqu1424rcxaxb4 is a lighting panelboard interior rated for 400 amps at 240 volts AC, single phase. It accommodates up to 42 circuits and stands 64 inches in height, making it a full-size interior assembly suited for commercial and light industrial electrical distribution systems. This interior unit is the replaceable inner assembly that mounts inside a compatible panelboard enclosure, housing the bus, breaker positions, and connection infrastructure. Licensed electricians install and service this type of component during new construction, tenant improvement, or panel upgrade projects.

This panelboard interior is designed for single-phase lighting and branch circuit distribution at 240 volts AC. With 42 circuit positions and a 400-amp main rating, it fits large commercial lighting and power distribution applications where high circuit density is required. Typical installations include commercial buildings, warehouses, retail spaces, and institutional facilities where a dedicated lighting panel is needed to manage multiple branch circuits from a single distribution point.

Key Features

• 400-amp amperage rating supports high-load lighting distribution systems
• 42 circuit positions provide high branch-circuit density in a single interior
• Single-phase, 240-volt AC configuration for standard commercial lighting applications
• 64-inch height accommodates full-size panelboard enclosures
• Interior assembly design allows field replacement without replacing the outer enclosure

Compatibility

Designed as an OEM-style replacement interior for compatible ABB lighting panelboard enclosures rated for single-phase, 240-volt AC service. Verify enclosure model compatibility with ABB documentation before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the upstream feeder before removing or installing any panelboard interior. Confirm that the enclosure dimensions, bus rating, and circuit configuration are compatible with this interior before mounting. Do not energize the panel until all branch circuit breakers are properly seated and all wiring connections are torqued per the terminal manufacturer specifications noted on the interior assembly itself.
