Leviton LP420-BPD – Frequently Asked Questions

1) What amp ratings does the Leviton LP-310 42-circuit panel come in?
Two: a 200A version and a 310A version, both 42-circuit and both 120/240V. The 310A is ordered as LP310-BPD and the 200A as LP420-BPD. Pick by the service size feeding the panel, not by circuit count, since the circuit capacity is the same either way.
2) Which Leviton part number do I order for a 200 amp service panel?
LP420-BPD is the 200A unit in the LP-310 42-circuit family. LP310-BPD is the 310A. Both are main breaker load centers at 120/240V, so the only ordering decision is the main rating.
3) My service already has a disconnect upstream. What is the equivalent to the Leviton LP-310 without a main breaker?
The Leviton LP-310 family is supplied as a main breaker load center with the main integrated into the panel. When the disconnect is handled upstream, a main lugs only panel is the corresponding choice: the Square D QO convertible main lugs load center with plug-on neutral in a NEMA 1 enclosure, the Square D Homeline 60-space 120-circuit 225A convertible main lugs load center in NEMA 1, or the ABB TL24415R MLO load center. The two Square D units are convertible, meaning they can be fitted with a main later rather than being MLO permanently.
4) Is the Leviton LP-310 the right panel for a 208Y/120V three-phase service?
No. The Leviton LP-310 is configured for 120/240V single-phase AC service, which is the common residential and light commercial arrangement. For a three-phase service, the ABB TL24415R is a 150A 3-phase 4-wire 208Y/120V MLO load center in a NEMA 3R enclosure. The two are not interchangeable on the same service, so confirm the utility configuration before ordering.
5) What can I use instead of the Leviton LP-310 load center if the panel is mounted outdoors?
The Leviton LP-310 is a main breaker load center for 120/240V AC service with 42 circuit positions, and its description covers service entrance and branch distribution work without stating a rainproof enclosure. For an exterior mounting location, the ABB ReliaHome load center is built with a NEMA 3R aluminum enclosure and plug-on neutral, and the ABB TL24415R is also a NEMA 3R unit. Both are the direction to look when the panel sits on an outside wall rather than in a utility room or garage.
6) Is 42 circuits enough for a house with electric heat and a large appliance load?
The LP-310 family gives 42 circuit positions on a 120/240V panel, which covers lighting, receptacles, appliance and HVAC branch circuits in most homes and light commercial spaces. If you are laying out a panel that needs more than that in one enclosure, the Square D Homeline 60-space, 120-circuit 225A load center is the higher-density option, though it is main lugs rather than main breaker.
7) Can I mount the Leviton LP-310 outdoors?
Treat the LP-310 as an indoor service and distribution panel unless the enclosure on the unit you receive is marked otherwise. For an outdoor or wet location you want a panel built with a rainproof enclosure, such as the ABB ReliaHome load center with its NEMA 3R aluminum enclosure, or the ABB TL24415R, also NEMA 3R.
8) Can I use breakers from another brand in a Leviton LP-310 load center?
Use Leviton branch breakers in a Leviton load center. Panelboards are listed with a specific breaker line, and a Square D QO or Homeline breaker is not interchangeable with a Leviton bus. If your building is standardized on Square D, the matching panel families are QO and Homeline rather than mixing breakers into this one.
9) I need more than 42 circuits. What load center goes beyond the Leviton LP-310 capacity?
The Leviton LP-310 family provides 42 circuit positions in 200A and 310A main breaker ratings. If the branch count exceeds that, the Square D Homeline 60-space 120-circuit 225A convertible main lugs load center carries substantially more positions in a NEMA 1 enclosure. Note that the Homeline unit is a main lugs configuration, so it needs an upstream disconnect or conversion to a main breaker, where the Leviton arrives with the main already integrated.
10) Do any of the alternatives to the Leviton LP-310 use plug-on neutral breakers?
Yes. The Square D QO convertible main lugs load center and the ABB ReliaHome load center are both specified as plug-on neutral designs, where AFCI and GFCI breakers seat directly on the neutral bar instead of using a pigtail. The Leviton LP-310 is described as a 42-circuit main breaker load center for 120/240V service; if plug-on neutral is a requirement on your branch breakers, those two are the ones that state it.
11) Will Square D Homeline or QO breakers fit the Leviton LP-310?
Treat them as separate systems. The Leviton LP-310 is a Leviton load center family, and the Square D units are the Homeline and QO series respectively. Branch breakers are specific to the panel bus they are designed for, so plan on Leviton breakers for the LP-310 and Homeline or QO breakers for those Square D panels. This matters most on panel replacements where an electrician hopes to carry existing breakers over.
12) Is this Leviton panel suitable for a service upgrade, or only new construction?
Both. Because the main breaker is integral and the panel is configured for standard 120/240V service, it works as a service entrance panel on new construction and as a drop-in replacement panel on a service upgrade. The 200A and 310A options let you size it to the service you are pulling in rather than reusing whatever the old panel was rated at.
