B-LINE U224 MTBL – Frequently Asked Questions
1) Can the B-Line U224 MTBL meter breaker be mounted outdoors on an exterior wall?
Yes. The U224 MTBL is built in a Type 3R enclosure, which is the rainproof rating used for outdoor service equipment, and it is a surface mount unit that fastens flat to the wall. The steel enclosure is galvanized and finished in ANSI 61 gray paint for outdoor exposure.
2) What size service conductors will fit the lugs on this Eaton B-Line meter breaker?
Both the line and load terminations accept #4 through 600 MCM conductors, so it takes anything from a small feeder up to a full 320 A class service entrance cable without adapters or reducers.
3) Is the U224 MTBL a ringless or ring type meter socket?
It is a ring type socket, so it needs a sealing ring at the meter opening rather than a ringless cover. Utilities specify one or the other, so if your utility standard calls for ringless, this is the wrong unit. It also has a manual circuit closing bypass and 4 jaws.
4) Will this meter main work for a single phase residential service fed from either overhead or underground?
Yes on both counts. The U224 MTBL is a 1 phase, 3 wire unit configured for overhead and underground feed, with 4 jaws for a single phase meter and 1 branch position for the main breaker. It is not suitable for a three phase service.
5) Is this meter breaker accepted by west coast utilities that require EUSERC drawings?
It is EUSERC approved and UL listed. EUSERC approval is what most western utilities ask for on service equipment submittals, so the unit can be submitted against their standard drawings. Confirm the specific drawing number your utility cites for a 320 A class, ring type, single position enclosure.
6) How much wall space and how much help do I need to hang this meter main?
The enclosure measures 30 in high, 27 in wide and 6 in deep, and it weighs 70 lb. That is a two person set on the wall, and you want the blocking or unistrut laid out before the unit goes up. The 6 in depth leaves room behind the deadfront for the 600 MCM bending radius.
7) Do I order the main breaker separately for the U224 MTBL, and what does manual circuit closing mean for the meter pull?
The enclosure has 1 branch position, so the main breaker is the device that fills it and you need to confirm the breaker is included in your order or specify it alongside. Manual circuit closing refers to the bypass: the lineman closes the bypass by hand so the meter can be pulled without dropping the load. That is why utilities ask for it on 320 A class self contained services.
8) What is the model number I should give my distributor for this Eaton B-Line meter main?
Order it as Eaton B-Line U224 MTBL. That is the manufacturer part number for the 3R, ring type, surface mount, 4 jaw single position unit in ANSI 61 gray.
