Abb TLM4220CCU 200A 42 Circuit Load Center 1 Phase

Product Description

The ABB TLM4220CCU is a field convertible, combination-type residential load center rated for 200 amps at single phase. Designed for main breaker or main lug configuration in the field, this load center supports up to 42 circuit spaces and carries a 22kA interrupting capacity (IC) rating. Electricians install this unit in residential and light commercial applications where panel flexibility during rough-in or service upgrades is a priority. The field-convertible design reduces the need to stock separate main breaker and main lug panels, making it a practical choice for electrical contractors managing diverse job requirements.

This load center is suited for single-phase residential installations, including new construction and service upgrades. The 42-circuit capacity accommodates full residential circuit loads, and the 22kA IC rating meets standard residential service requirements. It is installed by licensed electricians in accordance with NEC guidelines for panelboard installation and service equipment.
