B-LINE U225 MTBH MS45 – Frequently Asked Questions
1) Can the B-Line U225 MTBH MS45 meter socket be installed outdoors?
Yes. The U225 MTBH MS45 comes in a Type 3R enclosure, which is the rain-tight rating used for exterior wall-mounted meter equipment. The housing is galvanized steel finished in ANSI 61 gray paint for outdoor service.
2) How much wall space do I need for the B-Line U225 MTBH MS45 meter breaker?
Plan for a 22 inch wide by 30 inch high footprint with 6 inches of depth off the wall. It weighs 62 lb, so it is a two-person set on a ladder or a one-person job with the enclosure anchored first.
3) Is the U225 MTBH MS45 a 7-jaw socket for three phase service?
It is a 7 jaw, 3 pole socket wired for 3 phase, 4 wire service. Seven jaws is the standard configuration for a self-contained 3-phase 4-wire meter, so it will not accept a 4-jaw single phase meter. The unit has 1 breaker position.
4) Will the U225 MTBH MS45 work with an overhead service drop or only underground?
Both. The enclosure is built for overhead and underground feed, so the same unit covers a mast-and-drop install or a lateral coming up from below. Line and load terminations are side entry.
5) What size conductors can I land in the B-Line U225 MTBH MS45?
Line and load lugs both take #14 through 2/0 copper or aluminum range. If your service conductors are larger than 2/0, you will need a gutter tap or a different socket rather than trying to force the lug.
6) Will the utility accept this B-Line meter socket, and what is the short circuit rating?
The U225 MTBH MS45 is UL listed and EUSERC approved, which is what most western US utilities require before they will set a meter. It carries a 22 kAIC interrupt rating, so confirm your available fault current at the service point does not exceed that.
7) Does this B-Line meter socket take a ringless or ring type meter cover?
Ring type. The U225 MTBH MS45 uses a sealing ring to retain the meter, so it is not interchangeable with a ringless lift-off cover. Check which style your utility specifies for the district before ordering, since the two are not field convertible.
8) Does the U225 MTBH MS45 include a test block or bypass provision?
It is supplied with a test block, which lets the utility test or change the meter without dropping the load. That is a common utility requirement on commercial 3-phase installs.
9) What is the enclosure on this B-Line meter breaker made of, and will it hold up in a coastal or industrial setting?
The body is galvanized steel with an ANSI 61 gray painted finish. Galvanizing plus paint is the standard exterior service-equipment build; in heavy salt air, plan on periodic inspection of the paint and hardware rather than expecting a stainless-grade life.
10) How do I order the exact B-Line meter socket, and what is the part number?
Order by Eaton B-Line part number U225 MTBH MS45. That single designation locks in the 3R ring type enclosure, test block, 7 jaw 3 pole 3-phase 4-wire configuration, side entry, and the one-position breaker section, so there are no separate options to specify.
