Milbank U4367-XPF-BLG-PSEG – Frequently Asked Questions

1) Does the Milbank U4367-XPF-BLG meter socket include a main breaker or disconnect?
No. The U4367-XPF-BLG is a meter socket only, with no main breaker and no receptacles. You will need a separate service disconnect or main breaker panel downstream to complete the service. It is a single meter position, 5 terminal ringless socket rated 320 continuous amps at 600 volts AC, 60 Hz.
2) Is this Milbank socket the right one for a 400 amp residential service?
A 320 continuous amp socket like the U4367-XPF-BLG is what utilities commonly accept for what is marketed as a 400 amp residential service, since 320A continuous corresponds to the 400A non-continuous class. It is single phase, 5 jaw, which suits a 120/240V single phase service with a neutral. For a three phase service or a 200A class socket, this is not the part.
3) Can I use this meter socket for an underground service lateral, or is it overhead only?
Both. Cable entry is overhead or underground. It ships with a large closing plate and a 3 inch hub packed inside the socket, so you can install the hub for an overhead weatherhead riser or leave the closing plate in for an underground feed from below.
4) What is the difference between the two Milbank U4367-XPF-BLG options?
Both carry the 7/8 inch barrel lock provision. The difference is utility acceptance: U4367-XPF-BLG is the standard build, and U4367-XPF-BLG-PSEG is the version approved for Public Service Electric and Gas in New Jersey. If you are setting a service in PSE&G territory, order the PSEG version so the inspector and utility sign off.
5) What size lugs and terminals does this Milbank socket land conductors on?
Line and load terminations are 3/8 inch stud type, which is what you want for the parallel or large single conductors typical on a 320A service. Equipment grounding is handled by two barrel ground lugs. There are five terminations total on the 5 jaw single phase configuration.
6) What does the lever bypass on this Milbank 320A socket do for me?
The lever bypass lets an electrician or utility tech pull and replace the meter without dropping power to the load, which matters on occupied buildings where you cannot take the service down. It is a factory bypass provision on the U4367-XPF-BLG, not an add-on.
7) Will the Milbank U4367-XPF-BLG hold up outdoors on an exterior wall?
Yes. The enclosure is Type 3R, which covers rain, sleet and ice, and the body is G90 galvanized steel with a powder coat finish. It is UL Listed. Mounting is surface mount, so it lands flat on the wall or a backboard.
8) How much wall space do I need for this 320A Milbank socket?
Plan on 35.25 inches high by 13 inches wide, with a depth dimension of 4.844 inches off the wall. Leave working clearance in front per code for the service equipment.
9) Do I need a meter ring or sealing band with this socket?
No ring needed. This is a ringless design, so the cover itself secures the meter. For utility sealing it comes with a 7/8 inch knockout and angle bracket for a barrel lock. The barrel lock itself is not part of the socket, the utility normally supplies it.
10) Is the insulation in this Milbank meter socket suitable for a high current commercial service?
The jaw insulation is glass polyester, a thermoset material used for the higher continuous current classes. Combined with the 320 continuous amp rating and 600 volt AC rating, it suits commercial, multi-family and institutional service metering.
