Specification:
Primary electrical insulation (branch wiring in wet or dry locations): All splices for 600 volt
wire rated 105°C (220°F) and below shall be insulated with a minimum of two half-lapped
layers of Scotch® Super 33+™ Vinyl Electrical Tape. All connectors having irregular
surfaces shall be padded with 3M™ Scotchfil™ Electrical Insulation Putty or Scotch®
Linerless Rubber Splicing Tape 130C prior to insulating with Scotch® Super 33+™ Vinyl
Electrical Tape.
Mechanical protection (outer jacketing): All rubber and thermoplastic insulating high
voltage power cable tape splices and repairs shall be overwrapped with at least two half-
lapped layers of Scotch® Super 33+™ Vinyl Electrical Tape.
Installation
Techniques:
Scotch® Super 33+™ Vinyl Electrical Tape shall be applied in half-lapped layers with
sufficient tension to produce a uniform wind (for most applications this tension will
reduce the tape’s width to approximately 5/8 of its original width). On pigtail splices, the
tape shall be wrapped beyond the end of the wires and then folded back, leaving a
protective cushion to resist cut-through. Wrap tape up-hill, taping from a smaller
diameter surface to a larger diameter surface. Apply the tape with no tension on the last
wrap to prevent flagging.
