Milbank U3791N-RXL-200-BL – Frequently Asked Questions

1) Will the Milbank U3791N-RXL-200-BL meter socket work for a 200A residential service entrance?
Yes, that's exactly what it's built for. The U3791N-RXL-200-BL is a single-position, single-phase ringless meter socket rated 200 continuous amps at up to 240V AC, 60 Hz, with one 200A main breaker built in. Because the main breaker is integrated, it serves as the service disconnect, so you don't need a separate disconnect enclosure between the meter and the panel. It's UL Listed and Type 3R for outdoor mounting.
2) What size service entrance conductors can I land in the Milbank U3791N-RXL-200-BL?
Line side lay-in terminals take 6 AWG through 350 kcmil, and the load side takes 1 AWG through 300 kcmil. That covers the usual 200A service runs, including 4/0 aluminum SE cable on the line side and 4/0 aluminum or 2/0 copper feeding the panel. Lay-in terminals mean you drop the conductor in and torque it rather than fishing it through a hole. Equipment ground lands on the included 3 barrel ground lug.
3) Does my utility require a lever bypass meter socket, and what does the bypass actually do?
The lever bypass on the U3791N-RXL-200-BL lets the utility shunt current around the meter socket jaws so the meter can be pulled and swapped without dropping power to the load side. Many utilities mandate it on occupied buildings and on any service where an outage to change a meter is unacceptable, and some mandate it above a certain amperage. If your serving utility's meter spec calls for a bypass, this is the version to order; if it doesn't, a non-bypass socket is the simpler part. Check the utility's approved meter equipment list before you buy either way.
4) What is a ringless meter socket and will my utility accept one?
Ringless means the cover is held on by the enclosure itself rather than by a sealing ring clamped around the meter, so the utility seals the cover instead of a ring. Utilities are split: some specify ringless, some specify ring type, and they generally will not accept the other. The U3791N-RXL-200-BL is the ringless configuration with a 4 terminal (4 jaw) socket, which is the standard single-phase 3 wire arrangement. Confirm ringless is what your serving utility lists before ordering.
5) Can the Milbank U3791N-RXL-200-BL be used with an underground service lateral, or is it overhead only?
Either one. Cable entry is rated for overhead or underground, so the same part covers a weatherhead drop from a pole and an underground lateral from a pad transformer or pedestal. For an overhead feed you use the hub opening at the top; the socket ships with a large hub opening adapted to a small closing plate, so the plate closes off the opening when you don't need a hub, and you swap in the hub your utility specifies when you do.
6) Do I still need a separate service disconnect if I install this Milbank meter socket?
No. The U3791N-RXL-200-BL has one 200A main breaker integrated in the lower compartment, and that breaker is your single-point service disconnect and overcurrent protection. That lets you run from the socket straight to a main lug only panel, or to a subpanel, without a disconnect enclosure in between. On a plain meter socket with no main, you'd need that separate disconnect ahead of the panel or a panel with its own main.
7) Can I use this Milbank socket to meter two units or a three-phase service?
No on both. The U3791N-RXL-200-BL is a single-position socket, so it meters one service only; for a duplex or a multi-unit building you need a multi-position meter stack or one socket per unit. It's also single phase, 4 terminal, rated up to 240V AC, so it will not serve a three-phase service. There are no receptacles in the enclosure either, if you're looking for a socket with an integral convenience outlet.
8) Is this Milbank meter socket rated for outdoor mounting in a coastal or wet environment?
Type 3R, so it's rated for outdoor service and sheds rain, sleet and ice. The shell is G90 galvanized steel with a powder coat finish, which is the corrosion package you want on a wall exposed to salt air, humidity, or driving weather. Internal insulation is glass polyester. Type 3R is a rain-tight rating, not a watertight one, so it is not intended for direct submersion or washdown.
9) Does the Milbank U3791N-RXL-200-BL accept a utility barrel lock?
Yes. A 9/16 inch knockout and the angle bracket for a utility barrel lock are included, so the meter reader or utility crew can lock the cover without you fabricating anything on site. That's a common requirement on the utility's approved equipment list, and it's one of the details that gets a socket rejected at inspection when it isn't there.
10) What is the exact Milbank part number to order for a 200A ringless meter socket with main breaker and lever bypass?
Milbank U3791N-RXL-200-BL. That designation covers the ringless single-position socket, 200A continuous, one 200A main breaker, lever bypass, Type 3R, UL Listed. The UNSPSC classification is 39121102 if you're loading it into a procurement system.
