Abb PLM3220C Load Center Mlo 200A 32 Circuit Nema 1

Product Description

The ABB PLM3220C is a main lug only (MLO) load center rated for 200 amps with 32 circuit positions, housed in a gray NEMA 1 enclosure. MLO load centers do not include a main breaker, making them suitable for use as a sub-panel fed from an upstream disconnect or main breaker panel. The 32-circuit capacity provides ample space for branch circuit breakers in residential or light commercial distribution systems. Electricians and electrical contractors install this unit during new construction or service upgrades where a secondary distribution point is required.

The PLM3220C is applied in residential and light commercial settings as a sub-panel. Typical installations include detached garages, workshops, accessory dwelling units, and multi-family units where a downstream distribution point is fed from a main service panel. The NEMA 1 enclosure rating is appropriate for indoor, dry-location installations. The gray finish is standard for indoor panel installations and coordinates with common interior electrical room finishes.

Key Features

• 200-amp MLO rating supports high-capacity sub-panel applications without a built-in main breaker
• 32 circuit positions accommodate a full complement of single-pole and double-pole branch breakers
• NEMA 1 enclosure rated for indoor dry-location use
• Gray enclosure finish standard for residential and light commercial electrical rooms
• Plug-on neutral (PON) design simplifies neutral connection for compatible breakers

Compatibility

Designed as an OEM-style MLO load center for use as a residential or light commercial sub-panel fed from an appropriately rated upstream overcurrent protective device and disconnect.

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 feeder and verify the circuit is dead with a meter before beginning any wiring work. The MLO design requires that a properly rated main breaker or disconnect be located upstream of this panel. Secure the enclosure to a structural surface per manufacturer mounting instructions and ensure all knockouts and wiring entries are properly sealed and bushed.
