3M Performance Plus Wire Connectors T/Y+

The T/Y+ covers 22 AWG up to 12 AWG conductors (0.34 mm2 to 4 mm2 metric). That range is why it's dual color coded: one connector does the work of two traditional twist-ons in most applications, so you carry fewer part numbers on the truck. If you're making up 10 AWG or larger splices, this is not the connector for that job.

Yes, 600V is the rating on the Performance Plus T/Y+, with a maximum recommended voltage rating of 600.0 V. That covers standard 120/208/240/277/480V building branch circuits and lighting whips. The connectors are UL Listed.

The T/Y+ is rated to a maximum operating temperature of 105 C (221 F), which is the common requirement for fixture and ballast compartment splices. Confirm the fixture's own marked temperature limit, but 105 C is the rating that lets these be used where a 90 C connector would not qualify.

Maximum insulation outside diameter for the T/Y+ is 0.145 in (3.7 mm) per conductor. Standard building wire in the 22 to 12 AWG range falls under that, but heavy-wall or double-insulated conductors over 0.145 in will not seat properly in the shell and the skirt won't close over the splice.

The Performance Plus T/Y+ uses a flexible spring that expands, which 3M cites for both greater wire range and reuse. That matters on remodel and troubleshooting work where you're breaking down and remaking the same makeup in a box more than once. The spring is a strong-bite design for a secure connection on re-torque.

Two package options: a 100 Pack pouch, MPN 7010348896, and a standard pack, MPN 7010290543. The pouch is the one crews usually want in a pouch pocket for rough-in makeup; the standard pack is the bulk option for shop stock.

Completely different jobs. The 3M Performance Plus T/Y+ is a twist-on style connector for splicing conductors together inside a box, 22 to 12 AWG. A fitting like the Thomas & Betts 306 Straight Tite-Bite is a 1 inch FMC fitting that terminates flexible conduit to the box, and the RACO 4734 SWIVEL-LOK is a 1 inch Type B liquidtight connector for the same purpose. If you need to bring a raceway into an enclosure, you need one of those, not a wire nut.

No. The T/Y+ is a plastic-bodied twist-on splice connector topping out at 12 AWG, so it has no place on a grounding electrode or intersystem bonding termination. For that, a wall mount intersystem bonding connector such as the Burndy BDTIBB in stainless steel handles #14 through #2 AWG.

No. The Burndy BDTIBB is a wall mount intersystem bonding connector in the Bondit series, stainless steel, for landing #14 through #2 AWG bonding conductors at a common grounding point outside the building. The 3M Performance Plus T/Y+ is a twist-on wire connector for in-box branch circuit splices, rated to 600V and 105 degrees C, covering 22 AWG through 12 AWG. Use the BDTIBB for the intersystem bonding termination and the T/Y+ for conductor splices.

No. The 3M Performance Plus T/Y+ is a plastic twist-on connector whose shell insulates the splice on its own and is UL Listed as supplied. The Burndy UCCOVER1BOX25 is a polyethylene tap connector cover in the Tapit series, an added insulating cover fitted over a separate tap connector body. If your splice is made with a twist-on, no additional cover is part of the assembly.

Yes, for the splices. The RACO 232MSCM is a 4 in. square welded box, 2-1/8 in. deep, with a STAB-IT connector and an M bracket, so the integral connector handles cable entry into the box. Conductor-to-conductor joints made inside that box are a separate item, and the 3M Performance Plus T/Y+ twist-on covers 22 AWG through 12 AWG at 600V with a 105 degrees C rating for that purpose.

Country of origin on the 3M Performance Plus T/Y+ is the United States, which is the answer government and institutional buyers need for domestic-preference procurement language on a bid.
