21.2
Aluminum may be used as a current-carrying part if determined
to be acceptable with respect to heating, oxidation, and
connection of dissimilar metals. A connection between
aluminum and a dissimilar metal in which corrosion can occur
shall be evaluated by the heat-cycling test specified in the
Standard for Wire Connectors, UL 486A-486B.
No aluminum used
N/A
21.3
Plated iron or steel may be used for a current-carrying part:
No such parts
N/A
a) If acceptable in accordance with 2.1;
N/A
b) Within a motor, or associated governor; and
N/A
c) In a secondary circuit rated42.4 volts peak (30 volts rms),
60 V dc, or less.
N/A
Stainless steel and other corrosion-resistant alloys may be
used for current-carrying parts regardless of temperature.
N/A
21.4
Friction between surfaces is not acceptable as a means to
prevent shifting or turning of a live part, but a properly applied
lock washer is acceptable.
P
21.5
A live screwhead or nut on the back of a base or panel is to be
countersunk not less than 1/8 inch (3.2 mm) and covered with a
waterproof, insulating sealing compound that will not melt at a
temperature 15°C (27°F) higher than the normal operating
temperature of the component, but not less than 65°C (149°F).
N/A
Exception: A part that is staked, upset, or otherwise reliably
prevented from loosening need not be recessed and may be
insulated from the mounting surface by material other than
sealing compound or it may be acceptably spaced.

Internal Wiring
P
22.1
General
P
22.1.1
Unless it is to be judged as an uninsulated live part, insulated
internal wiring - including an equipment-grounding conductor -
shall consist of wire of a type or types acceptable for the
application, when considered with respect to:
Power cord and output cord
served as internal wire
P
a) The temperature and voltage to which the wiring is likely to
be subjected;
P
b) Exposure to oil, grease, cleaning fluid, or other substances
likely to have a deleterious effect on the insulation; and
N/A
c) Other conditions of service to which it is likely to be
subjected.
N/A
22.1.2
If the use of a short length of insulated conductor, such as a
short coil lead, is not practical, electrical insulating tubing may
be used on each conductor. The tubing shall be located so as
not to be subjected to sharp bends, tension, compression, or
repeated flexing, nor to contact with sharp edges, projections,
or corners. The tubing shall not be used in wet locations. The
wall thickness shall comply with the requirements for the tubing
as a component.
N/A
22.1.3
The length of power supply cord inside a power unit shall be
limited to that needed for electrical connections.
Not such application
P
22.1.4
Flexible-cord jacket inside the enclosure shall not be stripped to
expose the individual conductors unless:
P
a) The insulation on the individual conductors is equivalent to
that required by 22.1.1;
P
b) The individual conductors are supported in a manner
positively separating them from live and dead metal parts; or
