Milbank SC2992-RL – Frequently Asked Questions

1) Will the Milbank SC2992-RL 20A meter socket work for a 100A or 200A residential service?
No. The SC2992-RL is rated 20 continuous amperes, and its line and load lugs only take 12 to 10 AWG wire. That rules out a 100A or 200A dwelling service, where conductors are far larger. This socket is built for small metered loads, instrument or CT-type secondary metering, and similar low-current single-phase points. For a full house service you need a 100A or 200A meter socket with correspondingly larger lugs.
2) Can the Milbank SC2992-RL ringless meter socket be mounted outdoors?
Yes. It is a Type 3R enclosure in G90 galvanized steel with a powder coat finish, so it is built for rain-exposed outdoor wall mounting. It is surface mount, bolting flat to the wall rather than recessing into it. Note that it is listed as Non UL Listed, which matters if your utility or AHJ requires a UL label on metering equipment.
3) What does the auto bypass on this Milbank meter socket actually do for me?
The SC2992-RL uses an automatic (plunger-type) bypass, so when the meter is pulled the bypass closes and the load keeps power. For a property manager or utility tech, that means meter changes and testing happen without dropping the tenant or the circuit. A socket without bypass provision forces an outage every time the meter comes out.
4) Is this a 5-jaw socket, and will a 4-jaw meter fit it?
It is a 5 terminal (5-jaw) socket with triplex ground, single position, single phase. The fifth jaw is the neutral/ground terminal. Utilities that specify 5-jaw single-phase metering need this configuration; a 4-jaw-only requirement is a different socket. A 4-jaw meter does not land correctly in a 5-jaw base, so match the socket to what your utility will set.
5) Can I use this meter socket for an underground service lateral, or is it overhead only?
Either works. The SC2992-RL accepts overhead or underground cable entry, and it ships with a small hub opening closing plate, so you can fit a hub for overhead conduit or close the top off and bring conductors up from below for an underground lateral. The hub itself is sized to that small opening, so check the opening against the hub or conduit size your run calls for.
6) Does the Milbank SC2992-RL include a main breaker or disconnect?
No. It is a meter socket only, with no main breaker and no receptacles. If your installation needs service disconnect or overcurrent protection, that has to be a separate device, or you would specify a meter-main combination unit instead of this socket.
7) What voltage can this ringless meter socket be used on?
Rated 600 volts AC at 60 hertz, single phase. That covers standard North American single-phase utility voltages, 120/240V included, with margin. It is not a three-phase socket.
8) What is the difference between a ringless meter socket like this one and a ring-type socket?
A ringless socket, which is what the SC2992-RL is, uses a one-piece sealing cover that slips over the socket body and is sealed by the utility, instead of a separate locking ring clamping the meter in place. Utilities generally specify one style or the other, so confirm which your serving utility accepts before ordering. The socket itself is otherwise the same 5-jaw, single-position, single-phase arrangement.
9) What kind of terminals and insulation does the Milbank SC2992-RL use?
Connections are single mechanical lugs, one conductor per terminal, taking 12 to 10 AWG on both line and load side. The jaw assembly is mounted on glass polyester insulation, which holds up to heat and tracking in an outdoor socket. Since the lugs are mechanical and single, you cannot double-lug conductors in this base.
10) What is the Milbank part number I should order for this 20A ringless socket with bypass?
Order Milbank SC2992-RL. It falls in Milbank's CT20 product family, and the configuration is 5 terminal, ringless, small hub opening, plunger (auto) bypass, 20 continuous amperes.
