ABB Field-Convertible Combination Panelboard, 200A, 42-Circuit, 22kAIC
The ABB Field-Convertible Combination Panelboard is a 200A rated indoor panelboard built to serve as combination service entrance equipment, supporting either overhead or underground feeders depending on jobsite requirements. With 42 circuit spaces, a 22kAIC short-circuit rating, and 120/240V AC single-phase load regulation, this ABB panelboard is engineered for reliable residential and light commercial power distribution. The panelboard is UL listed, giving electrical contractors a code-compliant option for new construction and service upgrade projects where flexible feeder configuration and dependable fault-current protection are required.
Key Features
- Amperage Rating: 200A main rating supports whole-panel power distribution for residential and light commercial service.
- Circuit Capacity: 42-circuit configuration (42CRK) provides expanded branch circuit capacity for larger installations.
- Short-Circuit Rating: 22kAIC (22K) interrupt capacity delivers dependable protection under demanding fault-current conditions.
- Field-Convertible Design: Number of feeders is configurable as either overhead or underground, giving installers flexibility to match site-specific service entrance conditions.

ABB TLM4220CCU – Frequently Asked Questions
1) Can the ABB TLM4220CCU panelboard be used for an overhead service drop and an underground lateral?
Both. The TLM4220CCU is a field-convertible combination panelboard, so the feeder arrangement is configured on site as either overhead or underground. That is the point of the design: one part number covers a mast service or a service lateral without ordering two different enclosures. It is a combination service entrance unit, so metering and load center functions sit in the same cabinet.
2) Is the ABB 200A combination panel rated for outdoor mounting on the side of a house?
No. The TLM4220CCU carries an indoor enclosure rating, so it belongs in a protected location such as an electrical room, utility closet, or garage wall. For an exterior meter-main on a mast service you need an outdoor-rated combination unit instead.
3) Does a 22kAIC panelboard meet the available fault current on a 200A residential service?
The ABB TLM4220CCU is rated 22kAIC, which is the short-circuit interrupting rating of the panel. Utility transformers on typical residential and light commercial 120/240V single-phase services put well under that at the service point, but the available fault current on your specific service comes from the utility, not the panel. If your engineer has calculated a value at or below 22kA, this panel covers it.
4) Will this ABB panel work on a 208Y/120 three-phase commercial service?
No. The TLM4220CCU is a single-phase unit rated 120/240V AC, 1 phase. For a three-phase service you need a three-phase panelboard; putting a single-phase combination panel on a 208Y/120 three-phase feed is not a code-compliant install.
5) How many breaker spaces does the ABB TLM4220CCU actually give me?
42 circuit spaces. That is the branch capacity for a large house or a light commercial tenant space, and it is the number to check against your circuit schedule before you commit, since a 42-space panel is the ceiling before you go to a subpanel or a larger enclosure.
6) Is the ABB 200A combination panelboard UL listed for a permitted service upgrade?
UL Listed, built to UL standards. For an inspector on a service change or new construction, that listing is what lets the combination service entrance equipment pass on a 200A, 120/240V single-phase service. The listing mark is on the panel itself, so the inspection goes off the label.
7) What is the difference between a combination panelboard like this and a plain load center?
A plain load center is just breaker distribution; you still need separate metering equipment ahead of it. The ABB TLM4220CCU is combination service entrance equipment, meaning the metering section and the load center are in one cabinet. Fewer components to mount and wire, and one enclosure to get through inspection. If the meter is already set elsewhere on the building, a standalone main breaker load center is the simpler buy.
8) What part number do I give my supplier for the ABB 200A 42-circuit combination panel?
TLM4220CCU is the ABB manufacturer part number. That number carries the 200A rating, 42 circuits, 22kAIC, and the indoor combination configuration, so it is the single identifier to quote rather than describing the build.
