ABB TLM2412CCUG – Frequently Asked Questions

1) Does the ABB TLM2412CCUG come with a main breaker, or do I have to buy one separately?
It ships as a main lug panel. The TLM2412CCUG is convertible, meaning a main breaker can be installed in it later, but the breaker itself is not part of the panel as shipped. If you need main breaker disconnect at the panel for your service, plan on ordering that breaker as a separate line item.
2) How many circuits will an ABB TLM2412CCUG 125A load center hold?
There is space for 24 breakers at 1 inch each. Using tandem or twin breakers where the panel and code allow will raise the circuit count above 24, but the physical space is 24 one-inch positions on a 125A copper bus.
3) Is the ABB TLM2412CCUG rated for outdoor mounting?
No. It is a NEMA 1 indoor enclosure, combination/flush style. Mounting it outside, in a wet location, or anywhere exposed to hose-down or weather needs a NEMA 3R or better raintight panel instead. Indoor residential and light commercial walls only.
4) What voltage and phase does this 125A ABB load center work on?
120/240V ac, single phase. That is standard residential and light commercial service. It is not a three-phase panel, so a 208Y/120 or 480V three-phase distribution job needs a different panelboard.
5) What is the closest alternative to the ABB TLM2412CCUG if I need a higher amperage main lug panel?
The ABB TLM2412CCUG is a 125A convertible load center with a copper bus, factory-installed ground bar, and a NEMA 1 indoor enclosure, rated 120/240V ac single phase. If the service calls for more capacity, the Square D Homeline 60-space 120-circuit 225A convertible main lugs load center is also a convertible main lug design in a NEMA 1 enclosure, at 225A with 60 spaces instead of the ABB's space for 24 one-inch breakers. Both ship as main lugs with the ability to add a main breaker, so the wiring approach is the same; the difference is the bus rating and the circuit count.
6) Can I use a Square D QO load center in place of the ABB TLM2412CCUG?
They fill the same role but take different breakers. The ABB TLM2412CCUG is a PowerMark Gold convertible load center with space for 24 one-inch breakers and a copper bus, in a combination/flush NEMA 1 enclosure. The Square D QO convertible main lugs load center is a plug-on neutral panel in the QO series, also NEMA 1 and also convertible from main lugs to a main breaker. Breakers are not interchangeable between an ABB PowerMark Gold panel and a Square D QO panel, and the QO plug-on neutral bus is what lets QO combination arc-fault and ground-fault breakers snap on without a neutral pigtail. If you are standardizing a building on one breaker line, pick the panel that matches the breakers you already stock.
7) I need a main breaker panel, not main lugs. Do I have to buy a different load center?
Not necessarily. The ABB TLM2412CCUG ships in a main lug configuration but is convertible, meaning a main breaker can be installed in it for a service entrance setup, and it is suitable for use with service entrance equipment when installed per electrical code. The Square D Homeline 225A and the Square D QO plug-on neutral load centers are likewise convertible main lugs panels. In all three cases the main breaker is a separate item from the panel, so order the breaker that matches the panel line you choose.
8) Do I need to buy a separate ground bar kit for the ABB TLM2412CCUG?
No, the ground bar is factory installed in this one. Many load centers ship without it and force you to order a kit and drill it in, so on the TLM2412CCUG your equipment grounding conductors can land as soon as the can is set. A separate neutral/ground bonding decision still applies depending on whether this is the service disconnect or a subpanel.
9) What is the short circuit interrupting rating on this ABB panel?
22, per the published interrupt rating for the TLM2412CCUG, which is how ABB lists the series short circuit current rating in kA for this PowerMark Gold panel. Verify it against the available fault current at your service point before specifying.
10) Can I put Square D Homeline or QO breakers in an ABB PowerMark Gold load center?
Plan on ABB/GE-style PowerMark Gold breakers for this panel. Load centers are UL listed with specific breaker families, and Homeline and QO are Square D's own lines for their Homeline and QO panels. If you are standardizing breaker stock across a building on Square D, buy the Square D panel to match rather than mixing brands in the TLM2412CCUG.
11) For a small apartment unit panel, is the ABB TLM2412CCUG oversized compared to other options?
For a single dwelling unit, the ABB TLM2412CCUG at 125A with space for 24 one-inch breakers is a common size, and its NEMA 1 combination/flush enclosure suits an indoor wall in a unit or corridor. The Square D Homeline 225A convertible load center carries 60 spaces and 120 circuits, which is sized more for a whole-building or large-home service than a single unit. If you are repeating a panel across many units, the 24-space ABB is the smaller footprint of the two.
12) Which of these load centers supports plug-on neutral breakers?
The Square D QO convertible main lugs load center is the plug-on neutral panel of the group, which lets QO arc-fault and ground-fault breakers land on the bus without running a neutral pigtail to the neutral bar. The ABB TLM2412CCUG is a PowerMark Gold panel with a copper bus and a factory-installed ground bar, wired with conventional pigtailed AFCI and GFCI breakers. If your crew is trimming panels on a schedule and wants the faster terminations, that is the deciding difference.
13) Can the ABB TLM2412CCUG be used outdoors, or do I need a different panel?
The ABB TLM2412CCUG is a NEMA 1 enclosure rated for indoor use, so it is not the panel for an exterior wall, a meter pedestal, or a damp location. Both Square D comparables in the same convertible main lug role, the Homeline 225A and the QO plug-on neutral load center, are also NEMA 1. For an outdoor service you need a rainproof enclosure rather than any of these.
14) Copper bus versus aluminum bus in a load center, does it matter?
The TLM2412CCUG uses a copper bus. Copper bus is what many commercial and institutional specs call for, and some AHJs and engineers will reject an aluminum bus panel on a spec job, so if the drawing says copper bus this one satisfies it without a substitution request.
15) What is the exact ABB part number to order this 125A convertible load center?
The manufacturer part number is TLM2412CCUG, an ABB PowerMark Gold 125A convertible load center, 24 one-inch spaces, copper bus, NEMA 1 combination/flush enclosure, 120/240V single phase.
