Engineering Specification
3M Wire Connector T/R+ is capable of connecting two
or more wires in a pigtail application, in the wire range
of No. 22 thru No. 8 AWG solid and/or stranded
copper conductors. The connector shall be constructed
of an active (live) spring with a corrosion resistant
coating. The connector shall be UL LISTED and CSA
Certified as a pressure wire connector. The connector
shall be voltage rated 600 volts maximum building wire
and 1000 volts maximum signs and lighting fixtures
(luminaries). The connector shall have a maximum
operating temperature of 105˚C (221˚F).

Installation Instructions
CAUTION
Working around energized systems may cause serious injury or
death. Installation should be performed by personnel familiar with
good safety practice in handling electrical equipment. De-energize
and ground all electrical systems before installing product.
!
1. Strip wire insulation 1/2”.
2. Firmly grasp wires, making sure insulation ends
are even and tightly bundled. (Wires may be
twisted or untwisted.) Lead stranded wires
slightly. Slip the connector over wire tips.
3. Turn connector onto wires in clockwise
direction until secure.
4. To remove, turn connector counter- clockwise.
