11.2.4.4 A lead for connection to an ungrounded power supply conductor shall be identified by any color
other than white, gray or green with or without yellow stripes.
11.2.4.5 The surface of a lead intended for the connection of an equipment-grounding conductor shall be
green with or without one or more yellow stripes, and no other lead shall be so identified.
11.2.4.6 The requirements in 11.2.4.3 – 11.2.4.5 relating to color coding for identification do not apply to
internal wiring that is not visible in a wiring compartment in which field connections are to be made.
11.2.4.7 A wire-binding screw intended for the connection of a field connected equipment-grounding
conductor shall have a green-colored head that is hexagonal, slotted, or both. A pressure wire connector
intended for connection of such a conductor shall be plainly identified, by being marked "G," "GR,"
"GND," "Ground," "Grounding," or the like; or by a marking on a wiring diagram provided on the
appliance. The wire-binding screw or pressure wire connector shall be located so that it is unlikely to be
removed during normal servicing of the appliance.

12 Live Parts

12.1 A current-carrying part shall be silver, copper, a copper alloy, or other material acceptable for the
application.
12.2 Plated iron or steel may be used for a current-carrying part:
a) The temperature of which is more than 100°C (212°F) during normal operation,
b) Within a motor or associated governor, or
c) If acceptable in accordance with 3.1.1. Unplated iron or steel is not acceptable.
Stainless steel and other corrosion-resistant alloys may be used for current-carrying parts regardless of
temperature.
12.3 An uninsulated live part shall be secured to the base or mounting surface so that it will be prevented
from turning or shifting in position if such motion might result in a reduction of spacings below the
minimum acceptable values.
12.4 Friction alone between surfaces is not acceptable as a means to prevent shifting or turning of a live
part. A properly applied lock washer is acceptable.
