ABB TL MLO Combination Flush Load Center

The ABB TL MLO Combination Flush Load Center is a main lug only (MLO) load center family designed for use as either a home's main panel or a sub panel depending on the installation. This combination/flush enclosure line is available in amperage options ranging from 125 amperes to 200 amperes and in single-phase (1) or three-phase (3) configurations, allowing installers to match the exact bus rating and phase arrangement to the job. Every configuration in this family is built for indoor mounting, rated up to 60 degree/75 degree centigrade, and suitable for use with service entrance equipment when installed in accordance with electrical code, making it a dependable choice for residential and light commercial circuit distribution.

ABB TL412C – Frequently Asked Questions

1) Is the ABB TL load center a main breaker panel or main lug only?
It's main lug only. The ABB TL combination flush load center has no factory main breaker, so the feeder lands directly on the bus lugs. That lets it serve as a sub panel fed from an upstream overcurrent device, or as a main panel where the service disconnect and overcurrent protection are provided ahead of it. ABB lists it as suitable for use with service entrance equipment when installed per electrical code.
2) Does this ABB load center come in single phase and three phase?
Both. The ABB TL series is offered as a single-phase panel (TL412C, 125 amperes) and as three-phase panels (TL24415C at 150 amperes and TL42420C at 200 amperes). Three-phase is the one to pick for a 208Y wye feed in light commercial work; the single-phase version is the residential choice. The phase configuration is not field convertible, so order the one that matches the service.
3) Can I install this ABB panel outdoors or in a wet location?
No. The ABB TL combination flush enclosure is an indoor panel only. For an exterior wall, a meter socket location, or any damp or wet spot, you need a rainproof enclosure instead. Keep this one in finished interior walls, mechanical rooms, garages, and similar dry indoor spaces.
4) Which ABB TL panel should I order for a 200 amp three-phase sub panel?
TL42420C is the 200 ampere three-phase version. If the feeder is sized at 150 amperes, TL24415C is the three-phase option; for a 125 ampere single-phase job, TL412C. All three are main lug, so the overcurrent protection sits at the upstream panel and must be sized at or below the panel rating you choose.
5) How many breakers fit in the ABB TL24415C load center?
The 24CRT configuration gives space for 24 full-size 1 inch breakers. That count is the physical space, so tandem or half-size breakers, where the panel and code permit them, are not part of that number. Plan your circuit schedule against 24 single-pole spaces and remember every two-pole breaker consumes two of them.
6) What does a combination flush enclosure mean for mounting in a finished wall?
Combination means the enclosure can be set flush between studs behind a finished wall surface or mounted on the surface, so one part number covers both jobs. Flush mounting is the usual choice in finished living space where only the trim and door show; surface mounting suits unfinished walls, basements, and utility rooms. Either way, it is an indoor installation.
7) What conductor temperature rating can I terminate on the lugs of this ABB TL panel?
The panel is rated for 60 degree and 75 degree centigrade terminations. Size your feeder conductors from the 75 degree column only where the rest of the terminations in the circuit are also 75 degree rated; otherwise size from the 60 degree column. This matters most on the larger three-phase versions where feeder ampacity is tight.
8) Is the ABB TL load center a 4-wire panel, and do I need a separate ground bar?
It's set up for a 4-wire feed, meaning three phase conductors plus a neutral on the three-phase versions. Equipment grounding conductors land on a ground bar, which must be bonded to the enclosure when the panel serves as service equipment and kept isolated from the neutral when it is used as a sub panel downstream of the service disconnect.
