Milbank U4910-O-BL-ALT – Frequently Asked Questions

1) What size conductors can I land in a 200A Milbank U4910-O-BL meter socket?
Both line and load terminals take 6 AWG through 350 kcmil, and they are lay-in terminals, so you drop the conductor in rather than fishing it through a closed lug. That range covers the usual 200 amp copper and aluminum service conductors, including parallel-free 250 and 350 kcmil aluminum runs. Equipment ground lands on a ground lug in the can. The socket is rated 200 continuous amperes.
2) What is the difference between the U4910-O-BL and the U4910-O-BL-ALT?
Same 200A three-phase 7-terminal ringless socket either way. The -ALT suffix is the Alliant Energy version, built to that utility's acceptance requirements. If Alliant Energy is your serving utility, order the -ALT; anywhere else, the standard U4910-O-BL is the one to buy. Utilities reject sockets that are not on their approved list, so this is worth getting right before the meter set.
3) Does the lever bypass let me pull the meter without dropping power to the building?
That is what the lever bypass is for. Throwing the bypass carries the load around the meter so the meter can be pulled and replaced with the service still live, which is why utilities and large property owners specify bypass sockets on occupied buildings and tenant spaces. On a non-bypass socket the same meter change means the building goes dark. Rated 200 continuous amperes through the socket.
4) Is the Milbank U4910-O-BL meter socket rated for outdoor installation?
Yes, it is UL Listed and Type 3R rated, which covers rain, sleet, and ice on an outdoor wall. The shell is G90 galvanized steel with a powder coat finish over it, and the internal insulation is glass polyester. Type 3R is the standard rating for exterior service equipment; it is not a washdown or hosedown rating, so a Type 4 or 4X enclosure is the call for pressure-wash areas or coastal salt exposure.
5) What else do I need to order to finish a meter socket installation on an underground service?
The socket itself gives you the 7 jaws, the lay-in line and load terminals, the ground lug, and the lever bypass. Not in the box: the service disconnect or panel, since there is no main breaker in this can; the underground conduit, elbow, and any bottom-entry fitting to bring the service lateral in; conductors from 6 AWG up to 350 kcmil to suit the run; a grounding electrode conductor to land on the lug; mounting fasteners for your wall type; and the utility's barrel lock, which they normally supply for the 9/16 inch provision.
