ABB ReliaHome T-Series Convertible Load Center

The ABB ReliaHome T-Series Convertible Load Center ships main lug configured with the built-in capability to accept a main breaker, giving installers flexibility on the job site. Every ABB load center in this family is rated up to 60°/75° centigrade and is suitable for use with service entrance equipment when installed in accordance with electrical code. The T-Series is available in a range of circuit counts and bus amperage ratings — including 125A copper-bus configurations with 1" breaker spaces — and can be specified with NEMA 3R outdoor-rated enclosures for exterior installations or standard indoor enclosures depending on the job requirement. Electrical contractors rely on this platform for both new residential/light-commercial construction and service upgrades where a dependable, code-compliant distribution point is required.

ABB TLMQ1412RCU – Frequently Asked Questions

1) Can the ABB ReliaHome T-Series TLMQ1412RCU load center be installed outdoors?
Yes. The TLMQ1412RCU comes in a NEMA 3R enclosure, which is rated for outdoor and wet-location mounting. If the panel is going inside a garage, basement, or utility room, an indoor enclosure version of the T-Series is the one to spec instead.
2) Does the ABB T-Series convertible load center ship with a main breaker, or do I need to add one?
It ships main lug only. The cabinet and bus are built to accept a main breaker, so you can convert it to a main breaker panel on site, but the breaker itself is a separate item you order to match the 125A bus. For a service entrance job where a disconnect is required at the panel, plan on buying that main breaker.
3) What else could I use instead of the ABB ReliaHome T-Series convertible load center?
Two other convertible main lug load centers worth looking at: the Square D QO Convertible Main Lugs Load Center, a plug-on neutral NEMA 1 panel, and the Square D Homeline 60-space 120-circuit 225A Convertible Main Lugs Load Center, also NEMA 1. Both are indoor-rated cabinets, so neither is a drop-in for the ABB in a NEMA 3R outdoor location. The Homeline 225A is the one to look at when 125A of bus isn't enough for the service.
4) Does the ABB T-Series load center accept Square D Homeline or QO breakers?
No. The ABB ReliaHome T-Series TLMQ1412RCU uses ABB/ReliaHome breakers on 1 inch breaker spaces and is UL Listed as a system with those breakers. Square D Homeline and Square D QO are separate breaker lines that fit their own panels - the Homeline HOM-L225PC and the QO convertible main lugs load center - and are not interchangeable in the ABB bus. If you are standardizing breaker stock across a property, pick the panel family first, because the breaker line follows the enclosure.
5) What is the closest equivalent to the ABB ReliaHome T-Series TLMQ1412RCU if I need an indoor panel instead of an outdoor one?
The ABB ReliaHome T-Series TLMQ1412RCU is built in a NEMA 3R enclosure for outdoor and wet-location work, rated 125A at 120/240V and UL Listed. For an indoor installation, the Square D QO Convertible Main Lugs Load Center comes in a NEMA 1 enclosure and is likewise convertible from main lugs to a main breaker, so the wiring approach at the service point is the same. The Square D unit is a plug-on neutral design, which changes which breakers land on the neutral bar versus pigtail-connected AFCI/GFCI breakers in the ABB panel.
6) What voltage and wiring configuration does the ABB TLMQ1412RCU load center require?
120/240V AC, single phase, 3-wire. That's the standard residential and light-commercial service: two hots and a neutral, with the equipment ground landed separately. It won't serve a 3-phase panelboard application.
7) Does the ABB T-Series load center have a copper bus or aluminum?
Copper bus is available on the T-Series, including the 125A configurations with 1-inch breaker spaces. Copper is what a lot of spec writers and inspectors call out on service upgrades, so it's worth confirming the copper-bus configuration when you standardize on this panel across a portfolio.
8) What is the interrupt rating on the ABB ReliaHome T-Series load center?
22 is the stated interrupt rating for the T-Series. Check it against the available fault current the utility gives you at the service point; if the calculated fault current at the panel exceeds what the assembly is rated for, you need a different distribution solution rather than this one.
9) How many breakers fit in the ABB T-Series 125A load center?
The T-Series uses 1-inch breaker spaces, and the space count is set by the configuration you pick, sized to the selected circuit count. The 125A bus sets your ceiling on total connected load, not the physical space count, so size the panel by both the circuit count you need today and the room you want left for future adds.
10) For a multi-family building where I want one panel type on every unit, how do the ABB T-Series and the Square D options compare?
The ABB ReliaHome T-Series TLMQ1412RCU standardizes at 125A, 120/240V single-phase 3-wire, UL Listed, and is available in a NEMA 3R enclosure so the same family covers exterior meter-bank locations as well as indoor closets. The Square D Homeline HOM-L225PC is a 60-space 120-circuit 225A panel in NEMA 1, which suits a house panel or a large unit rather than a repeated small dwelling panel. The Square D QO convertible main lugs load center in NEMA 1 is the indoor plug-on neutral alternative. Standardizing on one family also standardizes the breaker stock your techs carry.
11) What is the difference between the ABB T-Series convertible load center and a plug-on neutral panel?
Both ship main lug configured with the ability to add a main breaker, so the conversion behavior is the same. The difference is at the neutral. The ABB ReliaHome T-Series TLMQ1412RCU is a conventional 120/240V 3-wire panel where AFCI and GFCI breakers land their neutral pigtail on the neutral bar. The Square D QO Convertible Main Lugs Load Center is a plug-on neutral design, where the neutral connection is made through the bus stab when the breaker is snapped in, which removes the pigtail landing for compatible breakers.
12) Where can I get the full spec sheet for the ABB TLMQ1412RCU load center?
ABB publishes a PDF spec sheet for this load center, linked in the product specifications, with the enclosure and mounting detail you'll want before cutting in a NEMA 3R panel on an exterior wall.
