Eaton 1MP3124R – Frequently Asked Questions

1) Will an Eaton 1MP group metering meter pack work on a 120/240V single-phase apartment service?
That's exactly the service it's built for. The Eaton group metering meter pack is rated 120/240V, single-phase in and single-phase out, with a 400A main bus feeding individual 125A metering sockets. It fits standard residential and light commercial multi-tenant service where each unit needs its own meter off one distribution point. If your building is fed three-phase or 208Y/120, this is not the pack for it.
2) How much load can each tenant draw on an Eaton 400A meter pack?
Each metering socket is rated 125A, and the assembly sits on a 400A main bus. That 125A socket rating is the ceiling on any single tenant position, so a unit needing a 200A service cannot be metered from a socket here. The 400A bus is what all the grouped sockets share, so the number of positions you can load and to what level has to fall under that bus rating.
3) Can an Eaton meter pack be mounted outdoors on an exterior wall?
Yes. The enclosure is rated indoor/outdoor, so it can go on an exterior wall at the service entrance or stay inside an electrical room. That matters on garden-style apartment buildings where the utility wants the meters accessible from outside without the crew entering the building.
4) What is the difference between Eaton meter pack 1MP2204R and 1MP3124R?
They're two different configurations within the same group metering family. Order by the part number, not by description: 1MP2204R and 1MP3124R are distinct assemblies, and swapping one for the other on a utility-witnessed install is the kind of mistake that fails inspection. Both carry the 120/240V rating and UL Listing.
5) How deep is the Eaton group metering meter pack for wall and clearance planning?
Product depth is 7.01 inches. Use that when you're laying out the electrical room or figuring how far the assembly stands off a finished exterior wall, and keep it in mind against the working clearance your inspector expects in front of the meter faces.
6) Is the Eaton meter pack UL Listed for a permitted multi-family service upgrade?
It's UL Listed, which is the listing an AHJ will look for on service equipment of this kind. For an institutional or multi-family job going through plan review, that is the line item on the submittal.
7) Should I use a group meter pack or individual meter sockets for a multi-tenant building?
A group metering pack consolidates the tenant meters into one assembly off a single 400A bus, so you pull one service and land one set of feeders instead of running separate service conductors to individual sockets scattered across the building. Individual sockets make more sense when the meter locations are genuinely remote from one another or when the utility requires separate service points. For a stacked apartment or condo building with a single service entrance, the grouped pack is the cleaner install and the fewer terminations.
8) Where can I get the Eaton meter pack spec sheet for a submittal package?
Eaton publishes a spec sheet for this meter pack, hosted at https://zensupply.com/content/pdf/eaton/spec-sheet-5ee0f7.pdf. That's the document to drop into a submittal or a permit set alongside the 400A bus, 125A socket, and 120/240V ratings.
