B-LINE U214 MTB MS43 – Frequently Asked Questions
1) Does the B-Line U214 MTB MS43 meter breaker come with the main breaker installed?
No breaker is included. The U214 MTB MS43 is a 100 A meter-breaker enclosure with the MCB provision, so you order and install the main circuit breaker separately. Plan for that on the material list before the inspection date.
2) Can this Eaton B-Line meter socket be mounted outdoors on an exterior wall?
Yes. It is a Type 3R enclosure, which is the rainproof rating used for outdoor service equipment, and it is a surface-mount unit rather than flush or semi-flush, so it fastens to the face of the wall or a backboard. The housing is galvanized steel with ANSI 61 gray paint for outdoor exposure.
3) Is the U214 MTB MS43 a single-phase or three-phase meter socket, and how many jaws?
Single phase, 3-wire (1 phase/3W), with a 5-jaw socket and one meter position. A 5-jaw single-phase socket is the configuration utilities specify when a neutral-carrying fifth jaw is required, so confirm your utility's jaw count on the service application. It will not serve a three-phase load.
4) What size service conductors will fit the lugs on this 100 A meter breaker?
The terminals take #6 through 250 MCM, which covers typical 100 A copper and aluminum service entrance conductors as well as oversized runs for voltage drop on a long lateral.
5) Will a ring-type meter socket work if my utility uses ringless covers?
No. The U214 MTB MS43 is a ring-type socket, meaning the meter is retained by a sealing ring over the cover lip. Utilities that require ringless equipment use a hinged or lift-off ringless cover instead, and they are not interchangeable. Check the utility's approved meter equipment list before ordering.
6) Is this meter socket accepted by west coast utilities that require EUSERC drawings?
It is EUSERC Approved, which is the approval western utilities reference for service equipment drawings, and the unit is UL certified. That combination is what a utility inspector looks for on a new residential or light commercial service.
7) How much wall space do I need for this B-Line meter breaker enclosure, and how heavy is it?
The enclosure measures 24 in high, 18 in wide, and 4.625 in deep, and it weighs 35 lb. That is a one-person set on a wall, but leave working clearance in front of the equipment per code and allow room below for the service conductors to enter.
8) What is the test block for on this Eaton B-Line meter breaker?
The U214 MTB MS43 is furnished with a test block, which lets the utility bypass or test the meter without dropping service to the load side. Some utilities require it on 100 A self-contained services and some do not, so match it to the utility's specification rather than assuming.
9) What model number should I order for this 100 A single-position B-Line meter breaker?
Order model U214 MTB MS43 from Eaton's B-Line series. That designation covers the 100 A, ring-type, 5-jaw, single-position, Type 3R surface-mount meter breaker with test block and no breaker included.
10) Is the ANSI 61 gray finish on this enclosure paintable to match a building?
It ships in ANSI 61 gray paint over galvanized steel, the standard utility equipment gray. Property managers who want it to disappear into a wall usually field-paint the exterior; keep paint off the meter sealing ring, nameplate, and grounding surfaces.
