Milbank U5091-RL-76GBGR – Frequently Asked Questions

1) Will the Milbank U5091-RL-76GBGR temp power pedestal work with my utility's 4-jaw ringless meter requirement?
The U5091-RL-76GBGR is a 4 terminal (4 jaw) ringless socket with a single power head, single phase, rated up to 240 volts AC at 60 Hz. That's the standard 4-jaw single phase residential/temp service configuration. Utilities differ on whether they accept ringless or require a ring type socket, so confirm ringless is approved on your service before setting the pole.
2) What receptacles and breakers come already installed in this 125A Milbank temp power unit?
It ships loaded: one NEMA 14-50 and two NEMA 5-20 ground fault receptacles, three receptacles total. Protection is one double pole 50 amp GFCI breaker feeding the 14-50 and two single pole 20 amp breakers for the 5-20s, three main breakers over two branch circuits. You don't buy breakers or devices separately for those positions.
3) Is this Milbank temp power socket set up for overhead service drop or underground feed?
Overhead. Cable entry on the U5091-RL-76GBGR is overhead, and the top is furnished with a small hub opening closing plate, so you install the hub sized for your service mast conduit. An underground lateral would need a socket built for bottom feed instead.
4) Can the meter be pulled on this unit without killing power to the site?
Yes, it has a lever bypass. Throwing the lever carries the load around the meter so the meter can be removed or changed while the connected receptacles stay energized. That's the feature utilities and service crews look for when meters get swapped on an active construction site.
5) Can this Milbank 125 amp temp power unit be left outside in the weather?
It is UL Listed and carries a Type 3R enclosure rating, which is the rain-and-sleet rating used for outdoor service equipment. The enclosure is G90 galvanized steel with a powder coat finish, and internal insulation is glass polyester. That is the normal build for a pole-mounted construction temp service exposed for the length of a job.
6) How big is the Milbank U5091-RL-76GBGR and how does it mount to a temp power pole?
Overall size is 4.844 x 10 x 34 inches, and it is a surface mount unit, so it fastens flat to the face of a 4x4, 4x6 or a plywood-backed temp pole. Plan on 34 inches of clear vertical run on the pole plus whatever height the utility requires to the meter center.
7) How do the service conductors and grounds land in this Milbank temp socket?
Line and load conductors land on lay-in terminals, so you strip and drop the conductor into the lug rather than threading it through a hole. Equipment grounding is handled by a ground bar in the enclosure. Continuous rating is 125 amps, so size the service conductors and the pole ground accordingly.
8) Will the 50 amp outlet on this Milbank temp pole run an RV or a welder?
The 50 amp position is a NEMA 14-50, the four-wire 120/240V configuration used by RV shore cords and many welders, and it is protected by a double pole 50 amp GFCI breaker. Check what your equipment's plug actually is: a 14-50 will not take a 6-50 or 10-50 cord without an adapter, and GFCI protection can nuisance trip on some older welding machines.
