Leviton LB220-GS – Frequently Asked Questions

1) What amperages does the Leviton LB-GS 2-pole GFCI breaker come in?
The Leviton Smart GFCI 2-pole branch circuit breaker is offered in five amperages: 20A (LB220-GS), 30A (LB230-GS), 40A (LB240-GS), 50A (LB250-GS), and 60A (LB260-GS). All are 2-pole GFCI devices, so you pick by the load on the circuit, 20A for a 240V receptacle or small equipment circuit, 30A for a dryer or small spa, 40A to 60A for ranges, EV charging, and larger hot tub loads.
2) Is the Leviton LB220-GS breaker rated for a 10,000 amp fault current panel?
Yes. The LB220-GS carries a 10kA short circuit current rating, which is the interrupting capacity most residential and light commercial load centers are specified at. If your panel schedule calls for a series or fully rated AIC above 10kA, this breaker does not meet it and you need a higher-AIC device.
3) Will a Leviton LB-series GFCI breaker fit in a Square D or ABB panel?
Plug-on breakers are panel-specific. The Leviton LB-GS series is built for Leviton load centers and panelboards, not for a Square D or ABB enclosure. If you are working in a Square D panel, look at Square D's own lines instead, the PowerPacT B thermal magnetic breaker for molded case applications or the Multi9 C60 and C60 UL489 miniature breakers for DIN rail work. For ABB panels, the A2 Series and E150 Series molded case breakers and the ST200M miniature breaker are the ABB-native options.
4) Is a Square D C60 DIN rail miniature breaker a substitute for the Leviton LB220-GS 2-pole GFCI breaker?
No. The Leviton LB220-GS is a GFCI device type in a 2-pole configuration built for load center and panelboard installation, so it provides ground-fault sensing on the branch circuit itself. The Square D C60 UL489 miniature circuit breaker is a DIN rail mount device, which is a different mounting method and a different enclosure approach. If the requirement on the drawing is ground-fault protection at the panelboard, stay with the Leviton GFCI breaker; the DIN rail MCB suits control panel and equipment enclosure work.
5) What should I use instead of the Leviton smart GFCI breaker if I need a 3-pole feeder breaker?
The Leviton LB220-GS series is a 2-pole device, so it will not serve a three-phase feeder. For 3-pole work, the ABB A2N Series molded case circuit breaker is a UL Listed 3-pole device, and the ABB E150 Series is a 3-pole thermal magnetic breaker. Note that both are thermal magnetic or molded case types rather than GFCI devices, so ground-fault sensing would have to come from elsewhere in the design.
6) Can I use an ABB ST200M in place of the Leviton 2-pole GFCI breaker on a branch circuit?
They are listed to different standards for different purposes. The ABB ST200M is a miniature circuit breaker to UL1077, which is a supplementary protector standard used to protect components inside equipment rather than to protect a premises branch circuit. The Leviton LB220-GS is a branch circuit breaker with GFCI protection and a 10 kiloamp short circuit current rating for panelboard service. For a branch circuit in a load center, specify the Leviton.
7) Do I still need a GFCI receptacle downstream if I install this breaker?
No. Ground-fault protection is built into the breaker itself, so it protects the entire branch circuit from the panel out, including hardwired equipment and any outlets on the run. That is the usual reason to spend on a GFCI breaker instead of a device, the load is hardwired or the receptacle is somewhere you cannot easily reach to test and reset.
8) What is the difference between this smart GFCI breaker and a standard molded case breaker?
Two different jobs. The Leviton LB-GS is a branch circuit breaker with ground-fault sensing built in, sized 20A to 60A for load center and panelboard circuits feeding receptacles and equipment. A molded case breaker like the Square D PowerPacT B or the ABB A2 Series is an overcurrent device for feeder and main applications, thermal magnetic protection without GFCI personnel protection. If code calls for ground-fault protection on the branch circuit, a molded case breaker alone does not satisfy it.
9) Can this 2-pole breaker protect a multi-wire branch circuit?
Yes, and that is a common use for it. A 2-pole breaker takes both ungrounded conductors of a multi-wire branch circuit and trips them together, which is what the common-trip requirement calls for. The GFCI sensing monitors both hot legs and the neutral together, so an imbalance anywhere on the circuit opens both poles.
10) Is the Leviton LB-GS GFCI breaker suitable for commercial panelboards or is it residential only?
Both. It is specified for residential and commercial panelboard installations, load center upgrades, and new construction panel work. The limiting factor for a commercial job is usually the available fault current, this breaker is rated 10kA, so confirm your service does not exceed that before you spec it into a commercial panel.
11) I only need a single-pole 120V breaker, not the 2-pole Leviton GFCI. What is the equivalent?
The Leviton LB220-GS is a 2-pole breaker rated 20A at 120/240V, so it is sized for multi-wire branch circuits and 240V loads. For a single-pole 120V AC circuit, the Square D Multi9 C60 is a 1-pole C-curve miniature circuit breaker rated 120V AC. It is a standard miniature breaker rather than a GFCI device, so it does not provide the ground-fault sensing the Leviton carries.
12) How does the Leviton LB220-GS compare to a Square D PowerPacT B breaker for a panel upgrade?
They solve different problems. The Leviton LB220-GS is a GFCI branch circuit breaker with a 10 kiloamp short circuit current rating, intended for branch circuit ground-fault protection in load centers and panelboards. The Square D PowerPacT B is a thermal magnetic circuit breaker, which trips on overload and short circuit but is not a ground-fault device. On a panel upgrade where the branch circuits need GFCI protection at the breaker, the Leviton is the one that answers that requirement.
13) I need more than 20A of GFCI protection. Does Leviton offer higher ratings, or do I move to a molded case breaker?
Stay in the Leviton family. The same 2-pole smart GFCI breaker is offered as the LB220-GS at 20A, LB230-GS at 30A, LB240-GS at 40A, LB250-GS at 50A and LB260-GS at 60A, so you can size up without giving up the GFCI function. Moving to a molded case breaker such as the Square D PowerPacT Q I-Line would change both the mounting into an I-Line panelboard and the protection type.
14) Where is the Leviton LB220-GS breaker manufactured?
Country of origin is China. This comes up on government, institutional, and federally funded work where domestic sourcing is a condition of the contract, so it is worth checking against your procurement requirements before the order goes in.
