ABB TM18410C – Frequently Asked Questions

1) Will the ABB TM18410C work on a 208Y/120V three-phase service?
That's exactly what it is built for. The TM18410C is rated 208Y/120V ac, 3 phase, 4 wire, so you get 120V to neutral on each of the three phases and 208V between phases. Do not use it on a single-phase 120/240V service or on 480V distribution.
2) Does the TM18410C come with the main breaker, or do I have to buy it separately?
The main breaker is factory installed. It is a 100 A main breaker load center, so you get single-operation shutoff of the whole panel out of the box. That is the difference between this and a main-lugs-only panel like the Square D Homeline convertible main lugs load center, where the disconnect has to be upstream or added.
3) Is the ABB TM18410C rated for outdoor mounting?
No. It is an indoor enclosure only, in a combination/flush design. For an exterior wall or a wet location you need a rainproof or NEMA 3R panel instead.
4) I need a single-phase panel for an apartment unit, not three-phase. Is this the right part?
No. The TM18410C is a 3-phase 4-wire, 208Y/120V panel, which suits a house panel fed off a 208Y service or a light commercial distribution point, not a standard 120/240V single-phase dwelling feed. For single-phase residential work look at a Square D QO or Homeline load center instead.
5) I need more than 18 circuits in one panel - what should I use instead of the TM18410C?
The ABB TM18410C is arranged for 18 one-inch breaker spaces, so once the branch count passes that you are into a larger enclosure. The Square D Homeline 225A convertible main lugs load center carries 60 spaces and 120 circuits in a NEMA 1 enclosure, which covers a much larger branch count on a 225 A bus. Note the tradeoff: the Homeline unit is a convertible main lugs panel, so the main disconnect is not included the way it is on the TM18410C, and the ABB is the 3-phase 4-wire unit at 208Y/120V ac.
6) What is the difference between the ABB TM18410C and a Square D QO convertible main lugs load center?
The difference is the disconnect. The ABB TM18410C ships with a main breaker factory-installed at 100 A, so the panel itself is the single-point shutoff for everything downstream. The Square D QO convertible main lugs load center is a main lugs design, meaning the feeder lands on lugs and the disconnecting means has to be provided ahead of the panel or by converting it with a separate main breaker kit. The TM18410C is also built for 3 phase, 4 wire service at 208Y/120V ac, while the QO unit is a plug-on neutral panel in the QO series. Choose the ABB when you need the breaker in the box and a 3-phase bus; choose main lugs when an upstream disconnect already exists.
7) The service here is single-phase 120/240V - can I still use the TM18410C?
It is not the right panel for that service. The ABB TM18410C is configured 3 phase, 4 wire for 208Y/120V ac systems, so its bus is built around a three-phase supply. For single-phase residential and light commercial service, a Square D QO convertible main lugs load center or a Square D Homeline 225A convertible main lugs load center in a NEMA 1 enclosure is the direction to look - just remember both are main lugs designs, so the disconnecting means has to come from upstream or a separate main breaker kit rather than being installed in the panel as it is on the ABB.
8) How many circuits can I get out of this 18-space ABB panel?
It is configured for 18 one-inch breaker spaces (18CRT). Full-size single-pole breakers give you 18 circuits; a three-pole breaker for a 208V three-phase load eats three spaces. Plan the phase balance before you fill it, because on a 3-phase 4-wire bus the single-pole slots rotate A-B-C down the panel.
9) Can the TM18410C be surface mounted, or is it flush only?
The enclosure is a combination/flush type, so it is intended to be recessed into the wall with the trim finishing flush, and the combination trim lets it serve either a flush or surface box condition. Feed is from the top, which is worth knowing before you set the conduit: run your service conduit into the top of the can, not the bottom.
10) What is the short circuit interrupt rating on the ABB TM18410C?
22, per the interrupt rating on the panel data, which on a load center of this class is read as 22 kAIC. Check it against the available fault current at your service point; if the utility calculation comes back higher, this panel is not the right choice for that location.
11) Is this ABB load center UL listed for a commercial building inspection?
Yes, the TM18410C is UL listed, with UL given as the governing standard. That plus the indoor enclosure rating is what an inspector will be looking for on an interior distribution panel.
12) Is a Square D Homeline load center a drop-in substitute for the ABB TM18410C?
No. Two things stop it. First, the Square D Homeline 225A unit is a convertible main lugs load center, so it does not arrive with the main breaker that the TM18410C has factory-installed. Second, breaker interiors are not interchangeable between manufacturers - Homeline panels take Homeline breakers, and the TM18410C is arranged for 18 one-inch ABB breakers. It is a valid panel for a different job, not a like-for-like replacement of an existing TM18410C interior.
13) For a flush indoor wall installation with a 22 kAIC requirement, does the TM18410C or a Square D main lugs panel fit better?
The ABB TM18410C is the one specified for that condition. It carries a 22 interrupt rating, is UL listed, and uses a combination/flush enclosure rated for indoor use with top feeder entry, so it drops into a wall cavity and takes conduit from above. The Square D QO and Homeline comparables are main lugs load centers, the Homeline in a NEMA 1 enclosure, and neither includes the factory-installed main breaker the ABB has - so meeting a panel-mounted disconnect requirement with them means adding a conversion kit or relying on an upstream device.
14) Ordering for a federal job, is the ABB TM18410C Buy American compliant?
BAA and ARRA status on the TM18410C both route back to ABB for confirmation, and country of origin is not established on the ABB record either. For a job with domestic-content language in the contract, get written confirmation from ABB on the specific production lot before you submit it.
15) What is the exact part number to order this ABB panel by?
ABB TM18410C. That single manufacturer part number covers the 100 A, 3-phase 4-wire, 208Y/120V, 18-space indoor main breaker load center, and there are no finish or trim variations to specify with it.
