Leviton LP620-MB – Frequently Asked Questions

1) Will a Leviton LP620 load center handle a 200 amp residential service upgrade?
Yes. The LP620 is a 200A main breaker load center with 66 circuit spaces, rated 120/240V, which covers a standard single-phase 200 amp service on a house or a light commercial building. The main breaker is integrated, so you get the service disconnect and overcurrent protection in the same can. Order the MB configuration if you want the main breaker arrangement; BPD is the other configuration offered.
2) Can the Leviton LP620 panelboard be mounted outdoors or in a wet location?
No. The LP620 enclosure is NEMA 1, which is indoor use only. It keeps out dust and incidental contact but is not rain tight, so it cannot go on an exterior wall, in a car park, or anywhere exposed to weather or washdown. For a meter main or exterior service location you need a NEMA 3R rated enclosure instead. Indoor electrical rooms, basements, and utility closets are where this one belongs.
3) Does the Leviton LP620 come with breakers, or do I have to buy those separately?
Breakers are not included beyond the main. The LP620 ships as enclosure and interior only, so the 200A main breaker and the bus are there but every branch circuit breaker is a separate line item. Budget your branch breakers by circuit count when you quote the job, and note there are 66 spaces to fill.
4) Will the Leviton LP620 work on a 208V three phase commercial service?
No. The LP620 is rated 120/240V, which is single phase. It is the wrong panel for a three phase service, whether 120/208V wye or 277/480V. For those you need a three phase panelboard rated for the system voltage. Where it fits is standard single phase residential and light commercial power, which is what most houses and small retail or office suites are fed with.
5) What is the difference between the LP620-MB and LP620-BPD?
Those are the two configuration options on the Leviton LP620. LP620-MB is the main breaker arrangement, LP620-BPD is the alternate panel arrangement. Both are the same 200A, 66 space, 120/240V panelboard in the same NEMA 1 white enclosure, so the choice is about how the panel is arranged for your job, not about capacity. Specify the suffix on the order, because the two ship as different part numbers.
6) Can this 200A Leviton load center go in an unheated garage or a cold mechanical room?
Yes, down to a long way below freezing. The LP620 is rated for operation to -40 degrees Celsius, so an unheated garage, a crawlspace mechanical area, or a cold northern utility room is within spec. The limit that governs the location is the NEMA 1 enclosure rating, not temperature, so the space still has to be dry and indoors.
7) Is a 66 circuit panel overkill, and when should I step up to this instead of a 40 space load center?
66 spaces is what you want when the circuit count, not the amperage, is the constraint. Large single family homes with heat pumps, EV charging, and subpanel feeders, plus small multi-tenant and light commercial services, run out of spaces long before they run out of the 200 amps. If your load calc lands at 200A but you only have 30 or so branch circuits, a smaller space count does the same job in less wall. The LP620 is the choice when you need room to grow inside one enclosure rather than adding a subpanel later.
8) How heavy is the Leviton LP620 panelboard, and is it a one-person install?
53 pounds for the enclosure and interior. That is a two-person lift onto a wall in practice, particularly at the height service equipment usually sits, and it is worth having the mounting screws started before you bring it up. The can is galvanized steel with a white finish.
9) Where is the Leviton LP620 load center made?
Mexico. That matters on public work where a buy-domestic clause is in the specification, so check the country of origin requirement against your contract before you submit the LP620 on a government or institutional job.
