Milbank U5310-O-55 – Frequently Asked Questions

1) Will the Milbank U5310-O RV pedestal work on a 240V 60Hz single phase site service?
Yes. The U5310-O pedestal is built for single phase service rated up to 240 volts AC at 60 hertz, with a 125 continuous ampere rating. That is the standard park service arrangement for RV sites, and it is what feeds the 30A and 50A RV receptacle options on the pedestal. Three phase service is out of scope for this unit.
2) What receptacle configurations can I get on the Milbank 125A RV power pedestal?
Five configurations plus a bare unit. You can order it as a base metered pedestal with no receptacles (U5310-O), a 20A duplex (U5310-O-11GR), a 30A RV (U5310-O-41), a 50A RV (U5310-O-55), a 30A/50A combo (U5310-O-75), or the lighted pedestal version of the combo (U5310-O-75-L). Pick the combo if you are serving mixed rigs on one site; the base unit is the one to order if you are adding your own receptacle assembly.
3) What size conductors can I land on the line side of the Milbank U5310-O pedestal?
The line side terminals accept 6 AWG through 350 kcmil, using double mechanical lugs. That range covers a direct-buried feeder from the park distribution panel all the way up to large aluminum conductors on a long run, so you usually will not need a splice box or reducers ahead of the pedestal.
4) Can I bring the feeder up from underground into this Milbank RV pedestal?
Underground is the intended entry. The U5310-O is a pedestal-mount unit with underground cable entry and a plain top, meaning there is no factory hub opening in the roof for an overhead service drop. If your site is fed overhead, this is the wrong configuration, and you want a hub-top meter socket instead.
5) Is the Milbank RV power pedestal rated for outdoor weather exposure?
Type 3R and UL Listed. Type 3R construction handles rain, sleet and ice formation, which is what a pedestal standing in an open campground site sees year round. The body is G90 galvanized steel with a powder coat finish for corrosion resistance, and the internal insulation is glass polyester.
6) Does the Milbank U5310-O meter socket have a meter bypass?
No bypass. The U5310-O is a no-bypass ring type socket with a single power head, so the meter has to be pulled to de-energize the load side. Many utilities require a lever or horn bypass on rental and RV park metering, so check your serving utility's meter equipment spec before you order this one, and specify a bypass socket if their spec calls for it.
7) Is this a ring type or ringless meter socket, and will my utility accept it?
Ring type, with a 4 terminal jaw configuration. Ring type means the meter is retained by a sealing ring the utility installs and seals, rather than by a ringless cover. Utilities publish one or the other as their accepted style, and they are not interchangeable in the field, so match the U5310-O's ring type 4 jaw arrangement against your utility's approved meter equipment list before setting the pedestal.
8) Can one Milbank U5310-O pedestal serve two RV sites?
No. It has a single power head with one meter position, so it meters and serves one site. For back-to-back sites sharing a pedestal you need a two position or duplex metered pedestal instead. The 30A/50A combo option (U5310-O-75) gives you two receptacle types on the one site, not two metered services.
9) How tall is the Milbank U5310-O RV pedestal and how much footprint does it need?
It measures 5.188L x 8.656W x 70.25H inches. The 70.25 inch height puts the meter and receptacles at working level once the base is set, and the narrow 5.188 by 8.656 inch body means the concrete pad or footing only has to carry a small footprint. Plan your pad and conduit stub-up around those base dimensions.
10) Does the Milbank RV pedestal come with grounding provisions or do I have to add a ground bar?
Grounding is included. The unit ships with 2 barrel ground lugs and a ground bar, so you can land the grounding electrode conductor and the equipment grounding conductors without adding an aftermarket kit. That matters on an RV pedestal, where the site feeder is typically a 4 wire run with grounds and neutrals kept separate downstream of the service disconnect.
11) Will 125 amps be enough for an RV site with a 50 amp coach?
Yes, with room to spare. The pedestal is rated 125 continuous amperes at up to 240V single phase. A 50 amp RV connection is 50 amps at 240V, so a single 50A site sits well inside that rating, and the 30A/50A combo pedestal still leaves headroom for the 30A and 20A branch loads. The limit to watch is the feeder you run to the pedestal, not the pedestal itself.
12) What is the difference between the Milbank U5310-O-75 and the U5310-O-75-L?
Same 30A/50A combo receptacle arrangement, but the -L is the lighted pedestal. The light is the version parks specify for sites where guests arrive after dark and need to find the receptacles and breakers. If site lighting is already handled by pole fixtures, the plain U5310-O-75 covers the same electrical function.
13) Is the Milbank RV pedestal only for campgrounds, or can I use it for temporary or construction power?
It works anywhere you need a metered outdoor 240V single phase drop up to 125 amps. Beyond RV parks and campgrounds, the same Type 3R pedestal is used for mobile home sites, temporary power at outdoor events and construction, and service staging areas. What decides it is the service arrangement: underground feed, single meter position, ring type socket, and the receptacle option you order on the front.
