ABB TLM812FCUD – Frequently Asked Questions

1) Is the ABB 125A main lug load center suitable for standard residential 120/240V service?
Yes. It is rated 125A at 120/240V AC, single phase, 3 wire, which is the standard split phase residential service arrangement. That covers a typical house subpanel or a small service, plus light commercial branch circuit distribution.
2) Main lug versus main breaker: does this ABB 8-circuit panel have a main disconnect?
No, it is a main lug only panel. Feeders land directly on the lugs, so there is no integral main breaker to shut off the whole panel. That means upstream overcurrent protection has to exist somewhere else, which is why main lug panels are normally used as subpanels fed from a breaker in the upstream board. It is configured to accept either a main or a sub feed.
3) I need an outdoor panel - does the ABB flush mount load center work, or do I need something else?
Do not use the flush indoor version outdoors. The ABB 8-circuit 125A load center is offered two ways: TLM812FCUD as a flush mount indoor NEMA 1 enclosure, and TLM812RCU as a surface mount outdoor NEMA 3R enclosure. For an exterior wall, specify the NEMA 3R surface mount version. The Square D Homeline 225A and QO plug-on neutral main lug load centers are both NEMA 1 enclosures, so neither of those is an outdoor substitute.
4) What is a bigger alternative to the ABB 8-circuit 125A main lug load center for a panel that needs far more branch circuits?
The ABB TLM812 load center is rated 125A at 120/240V and holds 8 circuits, which suits a compact branch distribution or sub-feed panel. When the load schedule outgrows that, the Square D Homeline 60-space 120-circuit 225A convertible main lugs load center in a NEMA 1 enclosure is the step up - it carries a 225A bus, 60 spaces for up to 120 circuits, and converts to a main breaker panel. Both are main lug designs, so the ABB is the choice for a small indoor flush pocket panel and the Homeline for a full service-size panel.
5) If I want plug-on neutral breakers instead, what load center should I use in place of the ABB 125A main lug panel?
The ABB TLM812 is a conventional main lug load center where neutrals land on the neutral bar. If your specification calls for plug-on neutral so AFCI and GFCI breakers snap directly to the neutral bus without a pigtail, the Square D QO convertible main lugs load center is the plug-on neutral option, also in a NEMA 1 enclosure. Both are main lug convertible-style panels for indoor use; the difference is the breaker interface and the QO breaker line it accepts.
6) Will Square D Homeline or QO breakers fit the ABB 8-circuit load center?
No. The ABB TLM812 load center accepts ABB/Thomas & Betts style breakers for its bus; the Square D Homeline 225A main lugs load center and the Square D QO plug-on neutral main lugs load center are built around the Homeline and QO breaker series respectively. Breakers are not interchangeable across these bus designs, so order breakers matched to whichever panel you install rather than assuming a common fit.
7) What does the 65 kA interrupt rating on this ABB load center mean for my install?
The panel carries a 65 kA interrupt rating, so it is suited to installations where the available fault current at the panel location is high, such as a point close to a large service transformer. Confirm the calculated available fault current at your point of installation is at or below that figure. The panel is UL Listed.
8) How many circuits does the ABB TLM812 hold, and what if I need more spaces?
It is an 8-circuit panel, sized for compact branch circuit distribution, a small subpanel, an addition, or a garage feed. For anything larger, look to a higher-space board such as the Square D Homeline 60-space 120-circuit 225A convertible main lugs load center in NEMA 1, or the Square D QO convertible main lugs load center with plug-on neutral.
9) Can I use this ABB panel as a subpanel off my existing main service?
Yes, that is a common use. The panel accepts either a main or sub feed, and because it is main lug only, feeding it from a breaker in the upstream service panel gives it the overcurrent protection it needs. On a subpanel the neutral and ground have to be kept separate per code.
10) Can I use the ABB 8-circuit load center as a service entrance main breaker panel?
The ABB TLM812 is a main lug load center, meaning the feeder lands on lugs and overcurrent protection comes from an upstream device; it is configured to serve as either a main or sub-feed panel. If you need a panel that can be field-converted to accept a main breaker, both Square D comparables are convertible main lugs designs - the Homeline 225A 60-space and the QO plug-on neutral - and convert to main breaker configuration with the appropriate kit.
11) Does the flush mount version of this ABB load center come with a door?
Yes. The indoor flush mount configuration is supplied with a hinged door, so the panel finishes flush in the wall with the interior concealed behind the cover.
