Product (Open
Specification)
The jacketed concentric neutral (JCN) and concentric neutral (CN) power cable splice shall
meet the requirements of ANSI/IEEE Std. 404 for a 15 kV rating, and must be rated by the
manufacturer for use on 15 kV class cable systems. It must be rated for continuous operation
at 105°C, with an emergency overload temperature rating of 140°C. The splice shall be
capable of splicing cables with copper or aluminum conductors sized from 2 to 4/0 AWG (35
to 95 mm
2
), 4/0 AWG to 350 kcmil (95 to 185 mm
2
), 350 to 750 kcmil (185 to 325 mm
2
) and
500 to 1000 kcmil (240 to 500 mm
2
) or accommodate a conductor size transition within those
size ranges. The splice shall be of a cold shrink design which does not require any additional
heat source for installation. The cold shrink splice body must be of a molded design made of
silicone rubber. The splice jacketing shall be of a cold shrink tubing made of EPDM rubber.
The color of the splice body and outer jacket shall be black.

(Closed
Specification)
Splicing of all 15 kV rated cables, jacketed concentric neutral (JCN) and concentric neutral (CN)
power cables, sized from 2 AWG to 1000 kcmil (35 to 500 mm
2
) copper or aluminum, shall be
performed in accordance with the instructions provided with the 3M™ Cold Shrink QS-III Splice Kits
5415A, 5416A, 5417A, 5417A-WG, 5418A and 5418A-WG.
