ABB TLM2020CCU – Frequently Asked Questions

1) Can the ABB TLM load center be set up as a main breaker panel or does it have to be main lugs?
Either. The ABB 20-circuit 200A convertible load center ships convertible, so it can be configured with a main breaker assembly or as a main lug feeder panel. That is what makes it usable both as a service entrance panel and as a downstream subpanel without stocking two different enclosures. The main breaker or main lug kit is a separate item you specify to match the job.
2) Can I mount this ABB load center outside on the side of a building?
No. The ABB TLM convertible load center is an indoor enclosure only, meant for electrical rooms, utility closets, and finished mechanical spaces. For an exterior service entrance or any wet location you need a rainproof enclosure instead. Installing an indoor-rated panel outdoors will fail inspection.
3) Will a 200A 1 phase 3 wire load center work on my 3 phase service?
No. The ABB TLM is a 1 phase, 3 wire panel rated 120/240V ac, which is standard single phase service with two hots and a neutral. If your service is 3 phase, 208Y/120 or 480Y/277, you need a three phase panelboard, not this load center.
4) What is the closest Square D equivalent to the ABB TLM2020CCU convertible load center?
The nearest peer is the Square D QO convertible main lugs load center, a NEMA 1 panel from the QO series that, like the ABB TLM series, ships convertible so it can be set up for main lug or main breaker service. The ABB unit is rated 200A at 120/240V AC, single phase, three wire, UL Listed, in an indoor enclosure. The QO peer differs in that it uses a plug-on neutral bus, which changes how QO plug-on neutral breakers land on the interior; ABB TLM panels take ABB/Thomas & Betts style branch breakers instead, so breaker stock is not shared between the two.
5) I need more than 20 circuits in one panel. What should I use instead of the ABB 200A convertible load center?
Step up to the Square D Homeline 60-space, 120-circuit 225A convertible main lugs load center in a NEMA 1 enclosure. It carries a higher 225A main rating and far more spaces than the 20-circuit ABB TLM panel, which is rated 200A at 120/240V AC. Both are convertible designs, so either can be fed through main lugs or fitted with a main breaker. Confirm your service size and available wall width before ordering the larger Homeline can.
6) Is 65 kAIC enough for a service with a high available fault current?
The ABB TLM convertible load center carries a 65 kAIC interrupt rating, which is well above the 10 kAIC and 22 kAIC ratings common on residential-grade load centers. That matters on services close to a large utility transformer, where the available fault current at the panel can exceed a standard panel's rating. Confirm the utility's available fault current at your service point against the 65 kAIC figure, and remember the branch breakers installed in it carry their own AIC ratings.
7) How many breakers does the ABB 20-circuit load center hold?
Twenty circuits. That's the count for both the 20 inch and 40 inch enclosure versions of this 200A ABB convertible load center, so stepping up to the taller box buys gutter and wiring room rather than more spaces. If you need substantially higher circuit density, look at something like the Square D Homeline 60-space, 120-circuit 225A convertible main lugs load center instead.
8) What else could I use instead of the ABB TLM if I want a plug-on neutral panel?
The Square D QO convertible main lugs load center is a plug-on neutral, NEMA 1 panel, which lets combination AFCI and GFCI breakers snap onto the neutral bar instead of running a pigtail to a neutral lug. The ABB TLM is a conventional convertible load center. If your job is heavy on AFCI/GFCI branch circuits, the plug-on neutral design cuts wiring time in the gutter noticeably.
9) Can I use this ABB panel as a subpanel fed from an existing main?
Yes, that's the main lug configuration. Set up as main lugs, the ABB TLM takes a feeder from an upstream overcurrent device and distributes branch circuits, which is the normal subpanel arrangement. Used that way you bond nothing at the panel: the neutral and ground bars stay separate and the equipment ground runs back to the service. As a main breaker panel at the service entrance, the bonding is made at the panel.
10) Does the ABB 200A load center come with breakers or a main breaker?
Packaging is 1 EA, the load center enclosure and interior itself. The main breaker or main lug assembly is chosen to suit the feeder configuration, and branch breakers are ordered separately. Price the panel, the main device, and the branch breakers as three line items when you're bidding the job.
11) Is the Square D Homeline 225A panel a drop-in replacement for an ABB TLM4020CCU?
No. The Homeline 60-space 120-circuit 225A convertible main lugs load center is a much larger enclosure with a higher amperage rating than the ABB TLM4020CCU, which is a 20-circuit 200A panel rated 120/240V AC for indoor use. The can size, gutter space, and feeder conductor sizing all differ, and Homeline branch breakers are not interchangeable with ABB TLM breakers. Treat it as a capacity upgrade requiring new rough-in, not a swap.
