3.11.14.2.2 Special application.- Approval must be obtained
for the type of insulated hook-up
from the contracting officer
wire to be used under the following conditions:
(a) Maximum potential to ground (rms value or equiva-
lent d.c.) exceeds 2500 volts.
(b) Ambient temperature inside a component may ex-
ceed 176F under specified service condition.
(c) The wire is used in a sealed component which
also incorporates heat-dissipattna parts (power
transformers, power resistors, and electron
tubes). (The volatile matter given off by some
types of wire insulation or jacketing may have a
deleterious effect on the component).
3.11.14.3 Passing through conduits.- Wire harnesses that pass
through conduits shall have two layers of tape conforming to

of broken or cut wires.
3.11.14.5 Protection. - Wires and harnesses shall be so placed
and protected as to avoid contact with rough or Irregular sur-
faces or sharp edges under service conditions. Wires shall not
be bent sharply where they enter Insulation material. Where wires

grommets or bushings shall be used for abrasion protection. The
use of friction tape is prohibited.
