B-LINE U214 MTBP – Frequently Asked Questions
1) Will the B-Line U214 MTBP meter breaker work for a 3-phase 4-wire service?
Yes. The U214 MTBP is a 7-jaw socket wired for 3-phase, 4-wire service at 100 A, with a single meter position. If your service is single-phase 3-wire, you want a 4-jaw or 5-jaw socket instead, not this one.
2) Can this Eaton B-Line meter socket be mounted outdoors on an exterior wall?
Yes. It's a Type 3R enclosure, which is rain-tight for outdoor wall mounting, built from galvanized steel with an ANSI 61 gray painted finish. It surface mounts, so you're fastening it to the wall face rather than recessing it into the framing.
3) What wall space do I need for the U214 MTBP meter breaker enclosure?
Plan on 24 inches high by 18 inches wide, with 4.625 inches of depth standing off the wall. At 39 lb it's a two-hand set for one person, and it needs to land on backing solid enough to carry that plus the conductors.
4) Is this meter socket set up for an overhead service drop or an underground lateral?
Overhead feed. The U214 MTBP is built for a service drop entering from the top. If the utility is bringing you an underground lateral, specify a bottom or underground-feed version of the series instead, because the hub and gutter arrangement is not the same.
5) What size service conductors will the lugs on this 100 A meter breaker take?
The terminals accept #6 through 250 MCM, so copper or aluminum service entrance conductors sized for a 100 A service land directly without a reducer or a pin adapter.
6) Will my utility accept this meter socket, and is it ring or ringless?
It is a ring type socket, meaning the meter is held by a sealing ring, and it is EUSERC approved, which is what most western US utilities require on their accepted equipment list. It is also UL listed. Utilities differ on ring versus ringless, so match whichever your local serving authority specifies.
7) Does the U214 MTBP include the main breaker, or do I order that separately?
It's a meter breaker (MCB) combination, so the main circuit breaker position is part of the unit rather than a separate downstream enclosure. That's the difference between this and a plain meter socket, which meters only and needs a separate service disconnect beside it.
8) What does the test block on this B-Line meter breaker do for me?
The test block lets the utility or a technician test and bypass the meter without pulling the service or interrupting power to the load. On commercial and multi-family services where an outage means a callback, it is often a utility requirement rather than an option.
9) How do I make sure I'm ordering the right unit out of the Eaton B-Line meter breaker series?
Order by catalog number U214 MTBP. The series splits by jaw count, feed direction, ring style and position count, so a neighbouring number can look identical on the wall and be wrong for your service. This one is the 100 A, 7-jaw, single-position, ring type, overhead feed, 3R unit with a test block.
