B-LINE 127 TB – Frequently Asked Questions

1) Is the B-Line 127 TB meter socket single phase or three phase?
Three phase. The 127 TB is built for a 3-phase, 4-wire service and carries 7 jaws, which is the standard jaw count for a 3-phase 4-wire self-contained meter. It is a single position socket, so it serves one meter only. If you are metering a single phase 3-wire residential service, you want a 4-jaw socket instead.
2) Can the 127 TB meter socket be mounted outdoors on the side of a building?
Yes. It is a surface mount enclosure with a Type 3R rating, which means it is rain, sleet and snow resistant for outdoor wall mounting. The shell is galvanized steel finished in ANSI 61 gray paint. It is not rated for washdown or dust tight locations, so an indoor process area with hose down cleaning needs a different enclosure type.
3) Is the 127 TB a ring type or ringless meter socket, and does that matter to the utility?
Ring type. The meter is held by a sealing ring rather than a hinged ringless cover, and many utilities specify one style exclusively. Check the utility's approved meter socket list before ordering, because a ringless jurisdiction will reject a ring type can at inspection.
4) Does the B-Line 127 TB have a bypass, and what kind?
It comes with a test block bypass, which lets the utility test or change the meter without cutting service. That is different from a lever bypass or a horn bypass, so if the utility spec calls for a lever bypass socket this is not the right model.
5) Is this meter socket UL listed and EUSERC approved?
The 127 TB is UL certified and EUSERC Approved, which is the approval Western US utilities most often require on service equipment. For a utility submittal, those two are usually the first line items the reviewer looks for.
6) Does the B-Line 127 TB work with an overhead drop or an underground lateral service?
Both. The 127 TB is built for overhead and underground feed, so the same socket covers a weatherhead drop or a lateral coming up from below. That is useful on a repeat spec where you do not know at order time which way the utility is bringing the service in.
7) What size opening do I need to plan for the 127 TB meter socket, and how heavy is it to set?
Plan for a 30 in high by 14 in wide footprint with 6 in of depth off the wall, and it weighs 38 lb, which is a one-man set on a solid substrate but worth a second pair of hands on a ladder. Allow clear working space in front per your local utility and code requirements.
8) What part number do I order for the Eaton B-Line 7 jaw test block meter socket?
Order it as B-Line 127 TB. The TB suffix is the test block bypass. It is a single model with no finish or size options, so there is nothing further to specify on the order beyond quantity.
