Yes. The 117 TB MS20 single meter socket carries a 3R enclosure rating, which is the rain-tight rating used for outdoor service equipment on an exterior wall. It is a surface mount enclosure, so it fastens to the wall face rather than recessing into it, and you will need to allow for its 4.625 inch depth standing off the wall.

Both the line and load lugs on the 117 TB MS20 take #14 through 2/0 conductors. That range covers the usual 100 amp service feeders, including 2/0 aluminum. If your service run is sized larger than 2/0 for voltage drop, you need a socket with bigger lugs or a separate reducing connection ahead of it.

Ring type. The 117 TB MS20 uses a ring style cover and includes a ring protector as a built-in feature. Utilities specify one or the other and they are not interchangeable, so if your serving utility calls for a ringless socket this is the wrong unit.

Yes, it is EUSERC approved and UL listed. EUSERC approval is what the western utilities look for on service equipment submittals, so this one clears that review for a 100 amp single position socket.

The 117 TB MS20 is built with a test block bypass. That gives the utility a fixed provision to bypass the meter so power stays on the load while the meter is pulled, tested, or changed out. Many utilities require test block or lever bypass on commercial sockets and will not set a meter without it, so check the utility's approved equipment list before ordering a plain non-bypass socket.

Plan on 24 inches high by 12 inches wide, with 4.625 inches of projection off the wall once it is surface mounted. It weighs 25 lb, so one electrician can set it, though holding it plumb while starting the anchors is easier with a second pair of hands or a temporary ledger.

No. The 117 TB MS20 is a single position socket, one meter only. For a duplex, a small strip mall, or any multi-tenant service you need a multi-position socket or a metering stack rated for the number of tenants, not several of these ganged together.

The enclosure is galvanized steel, which is the standard base for outdoor service equipment and pairs with the 3R rating for rain exposure. Galvanized steel holds up in normal exterior service; in heavy salt air, inspect and touch up any field-drilled penetrations so bare steel is not left exposed.
