B-LINE U217 MTB – Frequently Asked Questions

1) Is the B-Line U217 MTB meter breaker for single phase or three phase service?
Three phase, four wire. The U217 MTB is a 7 jaw socket, which is the jaw count used for 3-phase 4-wire metering, rated 100 A with a main circuit breaker in one position. A 4 jaw or 5 jaw socket is what you want for single phase service, so this one is not a substitute on a 120/240 V residential drop.
2) Can this meter breaker be mounted outdoors on an exterior wall?
Yes. It is a NEMA 3R rain-tight enclosure in galvanized steel with ANSI 61 gray paint, built for surface mounting on an exterior wall. 3R handles rain, sleet and snow but is not rated for washdown or hosedown locations.
3) What service conductor sizes will the lugs on the U217 MTB accept?
The terminations take #6 through 250 MCM, so it covers everything from a small 100 A copper feed up to 250 MCM aluminum where the utility or engineer has upsized for voltage drop or derating.
4) Is this an overhead or underground service unit?
Overhead feed. The U217 MTB is built for a service drop entering from the top. For an underground lateral coming up from below you need the underhead/underground feed version of the series instead, not this one.
5) Will the utility accept this meter socket, and is it a ring or ringless type?
It is a ring type socket, meaning it takes a sealing ring to retain the meter cover, and it is EUSERC Approved, which is the specification most Western US utilities write their service equipment to. It is also UL listed. Confirm with the serving utility whether their standard calls for ring or ringless before you set it.
6) What does the test block on this meter breaker do, and do I need it?
The test block lets the utility test or bypass the metering without pulling the meter and dropping the load, which is why many utilities require it on commercial 3-phase services. If your utility standard does not call for a test block, order the version of the series without it, since it adds cost and enclosure content you will not use.
7) Does this combine the meter and the main disconnect in one enclosure?
Yes. The U217 MTB is a meter breaker, so the 7 jaw socket and a main circuit breaker share one 3R enclosure in a single position. That means one set of service terminations and one wall penetration instead of a separate meter socket plus a downstream main, and the breaker serves as the service disconnect for the building.
8) What is the manufacturer part number to order this Eaton B-Line meter breaker?
Order it as U217 MTB, an Eaton B-Line series meter breaker. Give the utility that number along with the 100 A rating and 7 jaw 3-phase 4-wire configuration when you submit the service for approval.
