Milbank U4505-X-2/K2 – Frequently Asked Questions

1) Will the Milbank U4505-X meter socket accept my 350 kcmil service entrance conductors?
Depends which terminal option you order. The U4505-X-2/K2 comes with two double connectors rated 6 to 350 kcmil, so 350 kcmil lands at the top of its range. If you are pulling larger, the U4505-X-2/K3 uses two single connectors rated 4 to 600 kcmil. The base U4505-X is the 4-terminal version with a large closing plate.
2) Do I need a separate main breaker with the Milbank U4505-X socket?
Yes, you will need disconnecting means elsewhere. The U4505-X is a meter socket only, with no main breaker and no receptacles built in. It is a single meter position, so plan on a main breaker panel or a separate service disconnect downstream to meet your service requirements.
3) What is the difference between the 4-terminal and 5-terminal versions of this Milbank socket?
Terminal count is set by what your utility requires. A 4-jaw socket is the common single-phase 3-wire arrangement; the 5th jaw is used where the utility specifies a neutral or ground jaw for their metering. Milbank offers the U4505-X in both, so order to whatever your serving utility has approved rather than assuming. Electrically both are rated 320 continuous amperes, 1 phase, 600 VAC, 60 Hz.
4) Can I mount this Milbank ringless meter socket outdoors on an exterior wall?
Yes. It is UL Listed with a Type 3R enclosure, which is the rainproof rating used for outdoor service equipment, and the body is G90 galvanized steel with a powder coat finish. It is a surface mount unit, so it bolts flat to the wall rather than recessing into it.
5) Can the meter be pulled on this socket without killing power to the building?
That is what the lever bypass is for. Throwing the lever carries load around the meter so the meter can be removed or swapped without dropping service to the tenant or the facility. For property managers and utilities doing meter changes on occupied units, that is the reason to specify a bypass socket over a plain one.
6) What does ringless mean on a meter socket and will my utility accept it?
Ringless means there is no sealing ring around the meter; the cover itself goes over the meter and is sealed by the utility. Utilities are specific about this: some territories require ringless, others require ring-type, and they do not mix. The Milbank U4505-X is the ringless style, so confirm your serving utility's approved list before you set it.
7) Is a 320 amp meter socket the same as a 400 amp service?
No. 320 continuous amperes is the standard rating for what is commonly sold as a 400 amp residential service, since meter equipment is rated at 80 percent continuous. The U4505-X carries 320 continuous amps at 600 VAC single phase. If you have a true continuous 400 amp load, this is not the socket.
8) How much wall space do I need for the Milbank 320A meter socket?
Plan on a footprint of 15 inches wide by 28.25 inches high, with the enclosure projecting 4.844 inches off the wall. That depth matters most where the socket sits beside a doorway, in a meter bank line-up, or under a soffit.
9) Does this Milbank socket work for an underground service lateral, or only overhead?
Both. Cable entry is rated for overhead or underground, and it ships with a large closing plate over the hub opening so you can fit the hub or fitting your service requires. There is also a ground lug provided for the equipment grounding connection.
10) Can I use one Milbank U4505-X to meter two apartments?
No. It is a single meter position socket. For a duplex or a multi-unit building you need a multi-position meter socket or a meter stack with one position per tenant.
11) Will this Milbank socket hold up in a coastal or high-humidity install?
The enclosure is G90 galvanized steel with a powder coat finish over it, which is the corrosion package used on outdoor service equipment, and the internal insulation is glass polyester for thermal and electrical stability. Combined with the Type 3R rating, it is built for exterior mounting rather than a protected indoor location.
