Leviton LP210-3B – Frequently Asked Questions

1) Does the Leviton LP210-3B load center come with the main breaker and branch breakers, or is it just the enclosure?
Enclosure and door only. The Leviton NEMA 3R load center ships as the weather-rated housing configured to accept a main breaker, and you supply the main plus every branch breaker separately. Budget the breaker order alongside the panel, because a bare box on the wall does not energize anything. Two builds exist: LP210-3B is the 100A configuration and LP212-3B is the 125A.
2) Can a Leviton NEMA 3R load center be mounted outside on an exterior wall?
Yes, that is what the 3R rating is for. NEMA 3R construction sheds rain and protects the interior from outdoor exposure, so the panel is suited to service entrances, meter-main locations and other wet or outdoor spots on residential and light commercial work. Indoor-only NEMA 1 panels cannot go in those locations.
3) Should I order the 100A or the 125A version of the Leviton 20-space outdoor panel?
The choice is set by the service size feeding the panel, not by how many circuits you plan to run. Order LP210-3B for a 100A main and LP212-3B for a 125A main. Both are 20-space enclosures with the same 22kA short circuit rating, so the only difference is the main breaker the enclosure and door are configured to take. Size to the service conductors and the calculated load.
4) Is a 22kA interrupt rating enough for my service, or do I need a higher AIC panel?
22kA is the short circuit current rating on this Leviton outdoor load center, meaning it is rated to handle up to 22,000 amps of available fault current. On a typical residential or light commercial service fed from a utility transformer at ordinary distances, available fault current sits well under that. Where the utility or the engineer has stamped an available fault current above 22kA, usually a close-coupled large transformer, this panel is not the right box and you need a higher AIC-rated distribution panel.
5) What is the difference between the Leviton NEMA 3R load center and a Square D Homeline or QO panel?
Weather rating and breaker family are the two dividers. The Leviton is a NEMA 3R outdoor enclosure built to take a main breaker in a 20-space, 22kA configuration. The Square D Homeline 60-space 120-circuit 225A convertible main lugs load center and the Square D QO convertible main lugs load center with plug-on neutral are both NEMA 1, so they are indoor boxes only, and both are main lugs rather than main breaker. Breakers are not interchangeable between Leviton and Square D panels, so match the panel brand to the breakers you intend to stock.
6) I need an outdoor panel but this one is single phase residential. What else is there for a 208Y/120V three-phase service?
For three-phase outdoor distribution, the ABB TL24415R is a 150A 3-phase 4-wire 208Y/120V main lugs load center in a NEMA 3R enclosure. The Leviton 20-space NEMA 3R panel is set up for a 100A or 125A main breaker on residential and light commercial service, so it is the wrong box for a 208Y/120V three-phase feed. If you want another outdoor single-phase option, the ABB ReliaHome load center uses a NEMA 3R aluminum enclosure with a plug-on neutral interior.
7) What is the NEMA 3R alternative to a Square D Homeline load center for an outdoor service?
The Square D Homeline 60-space 120-circuit 225A convertible main lugs load center is a NEMA 1 enclosure, which is an indoor rating, so it is not suited to an outdoor or wet-location mounting. The Leviton LP210-3B and LP212-3B enclosure is rated NEMA 3R for outdoor use, with 20 spaces and a 22 kiloamp short circuit current rating, and accepts a 100A or 125A main breaker. For a service entrance mounted on an exterior wall, the NEMA 3R housing is the one that carries the outdoor rating; the Homeline would need to sit inside or in a separate weatherproof enclosure.
8) How many circuits will a 20-space Leviton load center actually give me?
Twenty spaces means twenty full-size breaker positions for branch circuits. How many circuits that becomes depends on what you put in them: twenty single-pole breakers is twenty circuits, and every 240V two-pole breaker for a range, dryer, AC condenser or EV charger consumes two of those spaces. Count your 240V loads first, then see what is left for lighting and receptacle circuits.
9) Can I use the Leviton LP212-3B as a main lug panel or a subpanel instead of a service disconnect?
The enclosure and door are configured to accept a main breaker, in the 100A build (LP210-3B) or the 125A build (LP212-3B). If what you need is a main lugs only panel fed from an upstream disconnect, look at a main lugs product instead: the ABB TL24415R and the Square D Homeline and QO convertible main lugs load centers are all MLO designs, though the two Square D units are NEMA 1 and belong indoors.
10) Is the Leviton 20-space NEMA 3R panel suitable for a main panel upgrade on an older house?
That is one of its intended uses, alongside new construction and outdoor service entrances. A 20-space box with a 100A or 125A main covers a typical single-family upgrade, and the 3R rating lets it sit outside next to the meter, which is often the simplest route on a rewire where there is no good indoor location. Where the load calculation lands above 125A, or the panel schedule needs more than 20 spaces, size up rather than fill this one to the last position.
11) How heavy is the Leviton outdoor load center enclosure, and is it a one-person mount?
42.75 pounds for the enclosure and door. That is a two-person lift to hold plumb against an exterior wall while you set the top fasteners, particularly off a ladder at service-entrance height. Plan the anchors for the wall type before the panel comes off the truck.
12) Where is the Leviton LP210-3B load center made?
Mexico is the country of origin for this Leviton outdoor load center. That matters on public and institutional work where the specification or the bid documents carry a domestic sourcing or trade agreement requirement, so check the origin language on the job before submitting it.
