ABB TL270RCU – Frequently Asked Questions

1) Can the ABB TL270RCU load center be mounted outside on an exterior wall?
Yes. The TL270RCU comes in an outdoor-rated enclosure, so it can be installed on an exterior wall for service entrance work. That is the configuration the panel is built in, so there is no indoor-only version of this model to confuse it with.
2) How many breakers fit in the ABB TL270RCU panel?
Two 1-inch breaker spaces, and that is the whole capacity. It is a small panel meant for a two-circuit job, a well pump and a disconnect, a hot tub feed, a shed or garage sub panel. If you need room to grow, step up to a larger load center; there is no way to add spaces to this one.
3) Is the ABB TL270RCU a main breaker panel or main lug?
Main lug. There is no main breaker in the TL270RCU, so incoming conductors land directly on the lugs. That means upstream overcurrent protection has to come from somewhere else, either the utility service disconnect or the breaker feeding it if you are using it as a sub panel. If your inspector wants a disconnecting means at the panel, a main lug unit will not satisfy it on its own.
4) Can I use the ABB TL270RCU as a sub panel off my existing house panel?
Yes, it is rated for either use. ABB lists the TL270RCU for use as a home's main panel or as a sub panel, so the same unit covers both. Fed as a sub panel it takes 120/240V ac, 1-phase, 3-wire, with the neutral and ground kept separate at the sub panel per code.
5) What size feeder can I run into a 70A load center like the ABB TL270RCU?
The bus is rated 70A at 120/240V, so that is the ceiling on the feeder you land in it. Terminations are rated for 60 and 75 degree C conductors, which is what you size your wire against. Do not feed it from a breaker larger than 70A.
6) I need a small outdoor panel for a two-circuit feed, but my supplier offered a Square D Homeline 60-space main lug load center instead. Is that a fair swap?
No, those are built for very different jobs. The ABB TL270RCU holds 2 one-inch breakers on a 70A copper bus in an outdoor-rated enclosure at 120/240V. The Square D Homeline HOM-L225PC is a 60-space, 120-circuit 225A convertible main lugs load center in a NEMA 1 enclosure, which is an indoor-only box sized for a whole-house or large sub panel distribution. If the application is a compact outdoor feed - a well pump, a detached garage, a small service entrance tap - the TL270RCU is the right size and the right enclosure. The Homeline only makes sense if you actually need dozens of circuits and have an indoor, dry location to mount it.
7) What is the difference between the ABB TL270RCU and a Square D QO plug-on neutral load center?
The Square D QO-112M100P is a convertible main lugs load center in the QO series with a plug-on neutral bus and a NEMA 1 enclosure, so QO-series breakers land on the neutral bar without a pigtail - convenient when you are installing a lot of AFCI or GFCI breakers indoors. The ABB TL270RCU is a 2-circuit, 70A main lug panel with a copper bus, a 65 kAIC interrupt rating and an outdoor-rated enclosure, UL listed and suitable for service entrance equipment when installed per electrical code. Choose by breaker family and location: QO breakers belong in the QO panel, ABB breakers in the ABB panel, and only the TL270RCU is built to hang outside.
8) The panel is going on an exterior wall. Which of these is actually built for that?
The ABB TL270RCU is the one specified for it - its enclosure is rated for outdoor installation and it is UL listed and suitable for use with service entrance equipment when installed per electrical code, at 120/240V with a 70A copper bus. The Square D Homeline HOM-L225PC and the Square D QO-112M100P are both NEMA 1 enclosures, which is an indoor general-purpose rating, so an exterior wall would require a different enclosure choice with those series.
9) Is the ABB TL270RCU bus copper or aluminum?
Copper bus. That matters to some specifiers and some inspectors who will not accept aluminum bus on a service entrance panel, and it is one of the details worth noting if you are standardizing panels across a property.
10) What should I use instead if I need more than two circuits?
Move to a full-size load center. ZenSupply carries the Square D Homeline 60-space, 120-circuit 225A convertible main lugs load center and the Square D QO convertible main lugs plug-on neutral load center, both NEMA 1, for indoor panel work. Note that NEMA 1 is an indoor enclosure, so if the panel has to live outside, the outdoor-rated TL270RCU or another outdoor-rated enclosure is what you want, not those.
11) Will 240V equipment work in the ABB TL270RCU, or only 120V circuits?
Both. The panel is a 3-wire, 120/240V ac single-phase unit, so the two spaces can take a pair of single-pole 120V breakers or one two-pole 240V breaker for something like a well pump, heater, or compressor.
12) We are standardizing panels across a multi-family property. Can we use the TL270RCU everywhere, or do we need something larger for the unit panels?
Use them for different roles. The ABB TL270RCU is a 2-circuit, 70A main lug panel - the right fit for outdoor service points, small sub-feeds and single-appliance disconnect-style installations, since its enclosure is rated for outdoor installation. For interior unit or house panels that need real circuit count, the Square D Homeline HOM-L225PC is a 60-space, 120-circuit 225A convertible main lugs load center, and the Square D QO-112M100P is a convertible main lugs load center with a plug-on neutral bus; both are NEMA 1, so they mount in dry indoor locations. Keep in mind that standardizing means standardizing breakers too - ABB and Square D panels take their own breaker lines.
13) Do any of these come with a main breaker, or are they all main lug?
All three are main lug designs. The ABB TL270RCU is a main lug load center that can serve as a home's main panel or as a sub panel depending on the application. The Square D Homeline HOM-L225PC and the Square D QO-112M100P are both described as convertible main lugs load centers, meaning they ship as main lug and accept a main breaker conversion kit. If your drawing calls for overcurrent protection at the panel itself, plan on a separate upstream device or the appropriate conversion hardware for the series you pick.
14) What is the exact part number to order this ABB outdoor load center?
TL270RCU is the ABB manufacturer part number, and it is a single configuration: 2-circuit, 70A, copper bus, outdoor enclosure, main lug. There are no finish or size options to specify.
