Wire Connectors Investigated
for Flexible Stranded Wire
Specifications:
Affected Standards:
To be UL and NEC compliant while using flexible stranded wire, it was necessary to use crimp-type ring lugs
investigated for flexible stranded wire. By using Marathon’s UL 486A-B investigated screw-type pressure connec-
tors in place of crimp lugs, you can save up to 66% of termination costs in material and labor.
Marathon’s wire approvals, in addition to Classes B
and C, now include stranding Classes G, H, I and
K. The photo shows two distinctly different strand-
ing classes, both 250 kcmil. The wire on the left,
Class B, has 37 strands.
Class K, has approximately 2499 strands. A table
providing information on wire sizes, Classes and
strand count can be found on the next page.
