Milbank U3342-O – Frequently Asked Questions

1) Does the Milbank U3342-O meter socket carry its own main breaker or bypass?
No on both counts. The U3342-O is a straight 13 terminal CT-rated socket enclosure with no main breaker and no bypass provision, so overcurrent protection has to come from upstream gear in your service. It is a single meter position, and there are no receptacles in the enclosure.
2) Why is a 13 terminal 600V meter socket only rated 20 amps?
Because it is a transformer-rated socket, not a self-contained one. The 20 continuous ampere rating is the meter circuit rating, not the service size. Service current runs through current transformers mounted on the CT rack provision inside the enclosure, and only the CT secondaries land in the socket. That is also why the line and load side wire ranges are 14 to 10 AWG, which is instrument wiring, not service conductors. If you were expecting to land service entrance cable on the socket lugs, this is the wrong type of socket.
3) Will the Milbank U3342-O work for a 120/240V single phase service?
No. It is built as a 3 phase, 600 VAC, 60 Hz transformer-rated socket with a 13 jaw configuration. A single phase service needs a single phase socket with the jaw count your utility specifies. Check the utility's approved meter socket list before ordering either way, since jaw count and terminal arrangement are dictated by them.
4) How much wall space do I need to mount this Milbank CT metering enclosure?
Plan on 36 inches wide by 52.5 inches high, with 11 inches of depth off the wall. It is surface mount, with a double front lift-off screw cover, so leave working clearance in front to pull both cover sections and get at the CT rack.
5) Can this meter socket be installed outdoors?
Yes. The enclosure is UL Listed and rated Type 3R, which is the standard rainproof designation for outdoor service equipment. Construction is G90 galvanized steel with a powder coat finish for corrosion resistance in exterior installs.
6) Is the top of this Milbank enclosure drilled for a conduit hub?
No, it ships plain top. Cable entry is configured for underground feed, so the design intent is conduit up from below rather than an overhead service drop through a hub. If you need a top entry, you would be drilling and adding a hub yourself, which affects the Type 3R rating.
7) Does the U3342-O let the utility test the meter without dropping the service?
It includes a test switch provision, which is the mounting space and prep for a test switch block so the meter can be tested and the CT secondaries shorted safely during maintenance. The switch itself is a separate item, and most utilities specify which make and model they will accept, so confirm that with them before you order the switch.
8) Do I need a ring type or ringless meter socket for my utility?
That is the utility's call, not the installer's, and they do not mix. The U3342-O is ring type, meaning the meter is retained by a sealing ring around the cover opening. Ringless sockets use a lift-off cover that captures the meter instead. Utilities standardize on one style per territory, so verify which your serving utility accepts before ordering this one.
9) Is there a grounding point inside this meter socket enclosure?
A ground lug is provided for the equipment grounding conductor. Terminals are single mechanical type, and the socket uses glass polyester insulation behind the jaws.
10) What is the exact Milbank part number for this 13 terminal CT socket, and what UNSPSC code should I use for procurement?
The model is Milbank U3342-O, a ring type meter socket. For purchasing systems, the UNSPSC classification is 39121102.
