Engineering Specification
Crimp-type terminals shall, electrically and mechnically,
connect to a pre-stripped end of a stranded copper wire
and have a flat tongue portion with a central opening for
mounting around a screw or stud.
The terminal line shall offer tongue variations in hole
(stud) size (6, 8 10, etc.) and configuration (ring, fork,
block fork, flanged block fork, locking fork, etc.): and
barrel variations in wire (AWG) size (22-18, 16-14,
12-10, etc.) and construction (non-insulated brazed seam,
vinyl insulated butted seam, nylon insulated with
insulation grip, etc.). The terminal line shall have
regulatory agency coverage (UL Listing, CSA
Certification). The terminal tongue shall be marked with
the wire range and manufacturer’s symbol ().
The nylon-insulated, ring tongue terminal with insulation
grip shall be tin-plated, annealed copper, with the tongue
having a specified stud hole (size 4 thru 1/2 in.) and a
butted seam barrel with a tin plated brass, funnel entry
insulation grip, covered by a molded nylon sleeve, color
coded and sized for a specified (AWG) wire range
(22-18, 16-14, 12-10).
Insulated terminals shall be UL Listed and CSA Certified
for 600 Volts maximum building wire: 1000 Volts
maximum in signs, fixtures and luminaries and have a
maximum operating temperature of 221°F (105°C).
Installation Information
UL Listed and CSA Certified for use on stranded copper
(AWG) wire only.
Strip away the end 3/8 inch of wire insulation.
Make the crimp in the proper station of a recommended
3M crimp tool: TH-440, TH-450 (scissor style), or
TR-482, TR-490 (ratchet style) hand tools.
