Installation
Techniques:
The 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.
Shelf Life:
Scotch Super 33+ Vinyl Electrical
Tape complies with the requirements
of UL 510 for storage. When
maintained under normal storage
conditions the tape will remain stable
and has a five year shelf–life.
