Abb TL30420C Mlo Load Center 200A 30-circuit 3ph 4W

Product Description

The ABB TL30420C is a main lug only (MLO) load center rated at 200 amps with a 30-circuit, 3-phase, 4-wire configuration for 208Y/120-volt systems. It accepts up to 30 single-inch breakers across 3 phases and is housed in a combination/flush enclosure. The bus is rated at 200 amps and is suitable for use as either a main panel or a sub-panel, depending on the installation layout. All ABB load centers in this series are rated for 60 degrees C and 75 degrees C conductors, keeping the unit compliant with a wide range of wiring configurations encountered in commercial and light industrial work.

The TL30420C is designed for 3-phase, 4-wire 208Y/120-volt distribution systems commonly found in light commercial buildings, multi-tenant residential properties, and larger residential installations requiring 3-phase power. Its MLO design makes it well suited as a sub-panel fed from an upstream main breaker or as a service entrance panel when installed in accordance with applicable electrical codes. Licensed electricians handling new construction, tenant improvements, or panel upgrades are the primary installers of this unit.

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 the upstream service and verify the absence of voltage before making any connections to the bus or lugs. The combination/flush enclosure should be properly secured to the mounting surface before wiring the panel. Verify conductor ratings match the 60 degrees C or 75 degrees C termination rating before landing wires.
