Milbank U5101-XL-75 – Frequently Asked Questions

1) What receptacles come on the Milbank U5101-XL-75 RV power outlet meter socket?
Three receptacles are built in: one NEMA 14-50, one NEMA TT-30, and one NEMA 5-20 GFCI. That covers a 50A travel trailer or fifth wheel, a 30A rig, and a 120V convenience outlet for tools or a trickle charger. Each is protected by its own breaker, a double pole 50A, a single pole 30A, and a single pole 20A.
2) Is the Milbank 125A RV pedestal socket rated for outdoor mounting?
Yes. The enclosure is Type 3R and UL Listed, built from G90 galvanized steel with a powder coat finish, so it is made to sit outside on a post or wall in rain and weather. It is a surface mount unit, not flush or pad mount.
3) Will the U5101-XL-75 work on a 240V single phase service, and what jaw configuration does it have?
It is a 1 phase unit rated up to 240 volts AC at 60 Hz, with a 4 terminal (4 jaw) ringless socket and a single power head. Four jaw ringless is the common residential and small commercial 120/240V single phase meter prep, so confirm with your utility that they accept a ringless 4 terminal socket before setting it.
4) What size feeder wire can I land in this 125A RV meter socket?
The line side lay-in terminals accept 6 AWG through 350 kcmil, which is a wide enough range to take anything from a small 125A feeder up to oversized aluminum. Lay-in terminals mean you drop the conductor in rather than threading it through a lug barrel, which makes utility hookup faster on a pedestal.
5) Does this Milbank socket have a meter bypass for hot-socket work?
No bypass provision on this one. Power has to be dropped at the source to pull or set the meter. If your utility requires a lever bypass or horn bypass on metered RV pedestals, this model will not satisfy that spec and you need a bypass-equipped socket instead.
6) Can I feed this RV pedestal socket from underground, or does it have to be overhead?
Either. Cable entry is rated for overhead or underground service, and the unit ships with a small closing plate for the hub opening, so you plate it over for an underground lateral or fit a hub for an overhead drop.
7) Is a metered RV pedestal socket the right choice, or should I use an unmetered power outlet panel?
Go metered when each site is billed individually, as in an RV park, campground, or mobile home park where the utility or park operator meters per stall. The U5101-XL-75 combines the 4 terminal ringless socket, the breakers, and the 50A/30A/20A receptacles in one 125A enclosure, so one box covers both the metering and the site power. If the site is sub-fed from a park panel and no separate meter is required, an unmetered RV power outlet panel is the simpler buy, since you would be paying for a socket the utility never sets a meter in.
8) How many branch circuits does this unit give me, and is there a place to land grounds?
Two branch circuits are provided, served by the three breakers (20A single pole, 30A single pole, 50A double pole), and a ground bar is included for equipment grounding conductors. The insulation on the socket is glass polyester.
9) Can I use this for a temporary construction power pole instead of an RV site?
It works wherever you need a metered 125A single phase drop with 50A, 30A, and 120V GFCI outlets, which covers temp construction power, event power, and marina pedestals as well as RV stalls. The Type 3R enclosure handles the outdoor exposure. The limit is the receptacle set: if your temp loads need a different configuration than one 14-50, one TT-30 and one 5-20 GFCI, this is not the box.
