Engineering Specification
3M T/R+ Wire Connector 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).

WARNING
Turn power off before installing or removing terminal. All electrical
work should be done according to appropriate electrical codes.
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.
