B-LINE U204 MS21 SS – Frequently Asked Questions
1) Will the Eaton B-Line U204 MS21 SS meter socket work on a 200 amp single phase residential service?
Yes. The U204 MS21 SS is rated 200A, single pole, 3 wire, with a 4 jaw meter block, which is the standard arrangement for a single phase 120/240V service. Line and load lugs both take #6 through 250 MCM conductors, so it accepts typical 200A copper or aluminum service entrance cable.
2) Is this meter socket set up for an underground service lateral or an overhead drop?
Underground. The U204 MS21 SS is built for a lateral feed, so the service conductors come up into the socket from below rather than through a hub on top. If the job has an overhead service drop, you want an overhead style socket with a hub opening instead.
3) Is the U204 MS21 SS meter socket suitable for outdoor mounting?
The enclosure carries a Type 3 degree of protection, which is a rain, sleet and windblown dust rated outdoor enclosure. The body is steel with a type 304 stainless steel finish, which is the reason people specify it for coastal and corrosive locations where painted galvanized socket bodies rust out.
4) Does this Eaton B-Line socket have a meter bypass, and does that matter for my utility?
No bypass. The U204 MS21 SS is a non bypass socket, so the meter has to be pulled to kill power downstream and there is no lever or horn bypass for hot meter changes. Many utilities require a manual bypass on 200A residential and small commercial services, so check the utility's approved meter socket list before ordering. If they require one, you need a bypass version of the socket, not this one.
5) Is this a ringless meter socket or a ring type?
Ring type. The U204 MS21 SS uses a sealing ring cover, so the meter is retained by a ring the utility seals. Utilities that standardize on ringless sockets with a full hinged cover will not accept it, so match the cover style to what the serving utility specifies for the area.
6) What size opening do I need to frame or clear for this meter socket?
The socket measures 15 inches high, 12 inches wide, and 4.625 inches deep, and it weighs 14 pounds. It is side mounted, so the mounting holes are through the sides of the enclosure rather than a back panel flange.
7) Is the B-Line U204 MS21 SS meter socket UL Listed?
Yes, the U204 MS21 SS is UL Listed. That is usually the first thing an inspector or utility checks before they will set a meter, along with the socket appearing on the utility's approved list.
8) Can I land 4/0 aluminum SER in this socket without adapters?
Yes. Both the line and load lugs on this 200A B-Line socket are rated #6 through 250 MCM, so 4/0 aluminum, and the usual 2/0 copper, land directly with no reducers or pin terminals.
