Milbank U4908-O-11GR – Frequently Asked Questions

1) Will the Milbank U4908-O-11GR temporary power unit work on a 240V single phase construction service?
Yes. The U4908-O-11GR is rated single phase, 60 Hertz, up to 240 volts AC, with a 125 continuous ampere rating. It's a 4 terminal ringless socket, which is the standard single phase residential/light commercial meter configuration, so it suits a temporary 120/240V service feeding a jobsite.
2) Does this Milbank temp power pedestal have a main breaker or a disconnect?
No main. The U4908-O-11GR carries two single pole 20 ampere breakers feeding the two receptacles, and it's listed as no bypass provision. If your utility or inspector requires a main disconnect ahead of the branch circuits, you need a different temp power unit with a main breaker, not this one.
3) What receptacles are on the Milbank 125A ringless temp power unit, and are they GFCI?
Two NEMA 5-20 ground fault receptacles, each on its own single pole 20 amp breaker. NEMA 5-20 is a 125V 20 amp configuration, so it takes both standard 5-15 cords and 20 amp T-slot plugs. GFCI protection is built in, which is what jobsite temporary power rules call for.
4) Is the Milbank U4908-O-11GR set up for overhead or underground service entrance?
Underground. Cable entry on the U4908-O-11GR is underground, and the top is a plain top hub closing plate, meaning there's no factory hub opening for an overhead weatherhead riser. If you're fed from an overhead drop, you want a unit ordered with a hub top instead.
5) Can this Milbank meter socket be left outside in the rain on a jobsite?
Yes. It's UL Listed with a Type 3R enclosure rating, which is rain and sleet resistant for outdoor use. The shell is G90 galvanized steel with a powder coat finish for corrosion resistance. Type 3R is not dust tight or washdown rated, so it's outdoor weather protection, not a hosedown environment.
6) How do I land the service conductors and the ground in this Milbank temp power unit?
The socket uses lay in terminals, so line and load conductors drop into the jaw terminals rather than threading through a closed lug, which speeds up termination on heavy temp feeders. Equipment grounding is handled by an included ground bar, and jaw insulation is glass polyester.
7) Ringless versus ring type meter socket for temporary power, which do I need?
That's set by your serving utility, not by preference. The Milbank U4908-O-11GR is a ringless design with a 4 terminal single position power head, where the cover itself retains the meter and no sealing ring is used. Utilities that require a ring type socket will reject a ringless can, so confirm the utility's approved socket list before ordering.
