ABB TL12412R – Frequently Asked Questions

1) Can the ABB TL18420R load center be mounted outdoors?
Yes. The ABB TL series load center comes in a NEMA 3R enclosure, which is the rating for outdoor rain-tight service. It can be set as a main panel or a sub panel on an exterior wall, and it is suitable for use as service entrance equipment when installed per the electrical code.
2) Is this ABB load center 3-phase or single phase?
Three phase, four wire, rated 208Y/120V ac. That makes it a commercial panel, not a typical 120/240V single phase residential panel. If the service feeding your building is single phase 120/240, this is the wrong panel. Check the service voltage at the meter before ordering.
3) What is the difference between the 125A and 200A ABB TL load centers?
Two bus ratings are offered: the TL12412R at 125 amperes and the TL18420R at 200 amperes. The 200A version carries the 18-space, 1 inch breaker configuration on a 200 A bus. Pick the bus rating to match the feeder or service ampacity ahead of the panel, not the connected load.
4) Does a main lug load center need a separate main breaker?
Main lug means there is no main breaker in the panel itself. Power lands directly on the lugs, so overcurrent protection has to come from upstream, either a main breaker at the service disconnect or the feeder breaker in the panel ahead of it. Used as a sub panel that is normal. Used as a service entrance panel, code limits how many disconnects you may have, so the disconnecting means has to be provided ahead of or at the panel.
5) What is the difference between the ABB TL18420R load center and the Square D Homeline 225A main lugs load center?
The ABB TL18420R is a 200A main lug load center in a NEMA 3R enclosure, wired for 3-phase, 4-wire service at 208Y/120V ac with room for 18 one-inch breakers. The Square D comparable is a Homeline series 60-space, 120-circuit convertible main lugs load center rated 225A in a NEMA 1 enclosure. The practical split is enclosure and service: NEMA 3R on the ABB is suitable for outdoor installation, while a NEMA 1 enclosure is an indoor-only box, and the ABB is set up for 208Y/120V three-phase distribution. The Homeline is also convertible, meaning it can be field-configured to accept a main breaker.
6) I need a main lug panel for an indoor electrical room, not outdoors. What should I use instead of the ABB 3R load center?
The ABB main lug load center is supplied in a NEMA 3R enclosure, which is built to take weather and is more box than an indoor electrical room needs. For an indoor location, the Square D QO convertible main lugs load center is a NEMA 1 enclosure with plug-on neutral, and the Square D Homeline main lugs load center is likewise NEMA 1 and rated 225A across 60 spaces. Both are convertible, so either can be field-converted to a main breaker panel if the inspector wants a disconnecting means at the panel.
7) Can I use a Square D QO or Homeline load center in place of the ABB TL load center on a 3-phase 208Y/120V service?
Not as a direct swap. The ABB TL load center is configured for 3-phase, 4-wire service at 208Y/120V ac on a 200A bus, which is what a commercial 208Y/120V system requires. The Square D comparables are the QO plug-on neutral convertible main lugs load center and the Homeline 60-space 225A convertible main lugs load center. The other thing that does not carry over is the breaker: the ABB panel takes 1-inch breakers, and QO and Homeline are each their own breaker footprint, so you cannot move a stock of breakers between them.
8) How many circuits will the 18-space ABB load center hold?
Eighteen spaces sized for 1 inch breakers. Full size single pole breakers take one space each; two pole breakers take two. If you plan on tandem or twin breakers to squeeze in more circuits, confirm the panel accepts them, since space count and circuit count are not the same number.
9) What short circuit interrupt rating does this ABB panel have?
65 is the stated interrupt rating, and the assembly is UL listed. On a commercial 208Y/120V service the available fault current at the panel has to be at or below the panel's rating, so this is the number your engineer checks against the utility's available fault current calculation.
10) What size conductors can I land on the lugs, and what temperature rating?
The lugs are rated for 60 degree/75 degree centigrade conductors, so size your feeders off the 75 degree column where the terminations and conductor insulation both allow it, and off the 60 degree column where they do not. That matters on a 200A feeder, where the difference between columns can change the copper or aluminum size you pull.
11) What indoor alternative is there if I do not need a NEMA 3R outdoor panel?
For a dry indoor location, ZenSupply carries the Square D QO Convertible Main Lugs Load Center with plug-on neutral in a NEMA 1 enclosure, and the Square D Homeline 60-space 120-circuit 225A convertible main lugs load center, also NEMA 1. Both are convertible, meaning a main breaker can be added later, which the ABB main lug panel does not offer. NEMA 1 is indoor only, so neither substitutes for the ABB in an exterior location.
12) Can I use this ABB load center as a sub panel off an existing 208Y/120V service?
That is one of its intended uses. Feed it from a breaker in the upstream distribution panel and land the three phase conductors plus neutral on the lugs. As a sub panel, keep the neutral and ground separated: the neutral bar must be isolated from the enclosure and the equipment ground run back to the source. Bonding is only done at the service equipment.
13) I only need a small sub panel, not 18 spaces. Is there a lighter option than the ABB 200A load center?
Within the ABB TL family, the TL12412R is the 125 ampere version and the TL18420R is the 200 ampere version, so stepping down to the 125A model is the closer move if you want to stay in the same NEMA 3R outdoor enclosure and the same breaker line. If the sub panel is indoors, the Square D QO convertible main lugs load center with plug-on neutral is a NEMA 1 alternative.
14) What does plug-on neutral on the Square D QO panel give me that the ABB TL load center does not?
Plug-on neutral is a busbar feature on the Square D QO convertible main lugs load center that lets AFCI and GFCI breakers pick up the neutral connection from the bus when the breaker snaps in, so there is no pigtail to land on the neutral bar. The ABB main lug load center is a conventional 200A, 18-space panel for 1-inch breakers in a NEMA 3R enclosure, so neutrals for its breakers land on the neutral bar in the usual way. If the job is heavy on AFCI circuits and wire management in the gutter matters, that is the difference worth weighing.
15) I need more than 18 circuits on a single panel. What are my options besides the ABB 18-space load center?
The ABB main lug load center is built around 18 one-inch breaker spaces on a 200A bus. If the circuit count outruns that, the Square D Homeline convertible main lugs load center is a 60-space, 120-circuit panel rated 225A in a NEMA 1 enclosure. Note the enclosure change: the ABB is a NEMA 3R outdoor-suitable box, so if the panel has to live outside, the alternative is a second ABB load center fed as a sub panel rather than the NEMA 1 Homeline.
