c) Supplementary insulation equivalent to that required
by 22.1.1 is provided on each individual conductor.
P
22.2
Protection of wiring
P
22.2.1
Internal wiring shall be protected if, when judged in accordance
with 8.1, it is accessible.
Not accessible
N/A
Exception: Internal wiring need not be protected if it is located
and secured within the enclosure so that it is not likely to be
subjected to stress or mechanical damage.
P
22.2.2
Wires within an enclosure, compartment, raceway, or the like
shall be located or protected to prevent contact with any sharp
edge, burr, fin, moving part, or the like that can damage the
conductor insulation.
P
22.2.3
A hole through which insulated wires pass in a sheet metal wall
within the overall enclosure of a power unit shall be provided
with smooth, rounded surfaces upon which the wires may bear,
to prevent abrasion of the insulation.
N/A
22.3
Electrical connections
P
22.3.1
Aluminum conductors, insulated or uninsulated, used as
internal wiring, such as for interconnection between current-
carrying parts or in a component winding, shall be terminated at
each end by a method acceptable for the combination of metals
involved at the connection points.
No AL conductor
N/A
22.3.2
With reference to 22.3.1, a wire-binding screw or a pressure
wire connector used as a terminating device shall be
acceptable for use with aluminum under the conditions involved
- for example, temperature, heat cycling, and vibration.
No wire-binding screw or a
pressure wire connector
N/A
22.3.3
A splice or connection shall be mechanically secure and shall
make acceptable electrical contact.
No splice or connection
N/A
22.3.4
A soldered connection shall be mechanically secured before
being soldered.
P
Exception: A wave- or lap-solder connection to a printed-circuit
board is considered acceptable without any further mechanical
security. A hand-soldered connection shall be mechanically
secured, by a means such as bending or the equivalent, prior to
being soldered.
N/A
22.3.5
A splice shall be provided with insulation equivalent to that of
the wires involved unless permanent spacings are maintained
between the splice and other metal parts.
No splice
N/A
Exception: This requirement does not apply to a splice within a
coil winding.
N/A
22.3.6
A splicing device such as a pressure wire connector may be
employed if it provides mechanical security and insulation
acceptable for the voltage and temperature to which it is
subjected.
No splice
N/A
22.3.7
If the voltage involved is less than 250 volts, insulation
consisting of two layers of thermoplastic tape, of two layers of
friction tape, or of one layer of friction tape and one layer of
rubber tape that has been investigated and found acceptable
may be used on a splice. In determining if splice insulation
consisting of coated fabric, thermoplastic, or other tubing is
acceptable, consideration is to be given to such factors as its
electrical and mechanical properties and its flammability.
Thermoplastic tape wrapped over a sharp edge is not
acceptable.
No splice
N/A
