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 non-insulated, butted seam ring tongue terminal
shall be tin-plated, annealed copper, with the tongue
having a specified stud hole (size 2 thru 1/2 in.) and a
butted seam barrel with a beveled I.D. for ease of
stranded wire entry, sized for a specified (AWG) wire
range (22-18, 16-14, 12-10).
Non-insulated terminals shall be UL Listed and CSA
Certified.
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-490 (ratchet style) hand tools.
