Milbank U9551-X – Frequently Asked Questions

1) Does the Milbank U9551-X meter socket include a main breaker or any branch breaker space?
No. The U9551-X is a meter socket only, with no main breaker and no receptacles. It carries one meter position and 5 jaws. If your service needs overcurrent protection at the meter, you need a separate main disconnect downstream or a meter-main combination unit instead of this socket.
2) Will 4/0 aluminum SE cable land in the Milbank U9551-X?
Yes. Both the line and load lugs on the U9551-X accept 6 AWG through 350 kcmil, so 4/0 for a 200 amp service is well inside the range. They are lay-in terminals, so the conductor drops in rather than threading through a barrel.
3) What does the lever bypass on a Milbank 200A ringless socket actually do for the installer?
The lever bypass lets a utility or electrician pull and reinstall the meter without dropping power to the load. You throw the lever to shunt current around the meter jaws, then remove the meter. On a tenant service or a light commercial panel that cannot go dark for a meter swap, that is the reason to spec bypass over a plain socket.
4) Can the Milbank U9551-X be mounted outdoors on an exterior wall?
Yes. It is a surface mount enclosure rated Type 3R and UL Listed, built from G90 galvanized steel with a powder coat finish, so it is intended for outdoor wall mounting with protection against rain and sleet. It is not a flush or recessed can.
5) What is the difference between the Milbank U9551-X options when I order?
Four configurations are offered on the U9551-X. The base U9551-X puts the 5th terminal at the 6 o'clock position. U9551-X-DPL adds a large closing plate. U9551-X-PEP is the large closing plate version built to PEPCO approval, which matters if you are working in that utility's territory. U9551-X-QG-HSP comes with a quadplex ground and a stainless steel hasp for sealing. The electrical ratings are the same across all four; pick by what your serving utility accepts.
6) Can I use this socket for an underground service lateral, or is it overhead only?
Either. The U9551-X accepts overhead or underground cable entry, so the same socket works for a weatherhead drop or a lateral coming up from a meter pedestal or trench. Knockout selection at install determines which you use.
7) Will a Milbank U9551-X work on a 3-phase service?
No. This is a single phase, 5-terminal socket. Running it on a three phase service is the wrong application; you need a 7-jaw three phase socket for that. Check the phase configuration on the utility's service card before ordering.
8) Is a ringless socket like this compatible with my utility's meter, or do I need a ring-type?
Ringless means the cover itself secures the meter, sealed by the utility, rather than a separate sealing ring around the meter rim. Many utilities standardize on one or the other and will reject the wrong style at inspection. The U9551-X is ringless with a closing plate, and the PEPCO-approved version is listed specifically for that utility's requirements.
9) What insulation is used inside the Milbank U9551-X socket?
The jaw block is glass polyester, which holds up to heat and keeps the terminals electrically isolated at the 600 volt AC rating. That matters on a 200 amp continuous service where the socket sees sustained load and outdoor temperature swings.
