12.4.3
If a knot in a flexible cord serves as strain relief, the surfaces
that the knot may touch shall be free from burrs, fins, sharp
edges, and projections that can damage the cord.
No knot
N/A
12.4.4
Means shall be provided to prevent the flexible cord or lead
from being pushed into the enclosure through the cord-entry
hole when such displacement results in:
P
a) Subjecting the supply cord or lead to mechanical damage;
P
b) Exposing the supply cord or lead to a temperature higher
than that for which it is rated;
P
c) Reducing spacings (such as to a metal strain-relief clamp)
below the minimum required values; or
P
d) Damaging internal connections or components.
P
To determine compliance, the supply cord or lead shall be
tested in accordance with Section 47, Push-Back Relief Test.
P
12.5
Bushings
P
12.5.1
A bushing or the equivalent shall be provided at a point where a
flexible cord passes through an opening in a wall, barrier, or
enclosing case. The bushing shall be substantial, mechanically
secured in place, and shall have a smooth, rounded surface
against which the cord may bear. If a Type SP-2, SPE-2, or
SPT-2 cord is employed, the wall or barrier is of metal, and the
construction is such that the cord may be subjected to stress or
motion, the bushing shall be an insulating bushing.
Bushing used
P
Exception: For a cord hole in wood, porcelain, phenolic
composition, or other nonconductive material, a smooth,
rounded surface is considered to be the equivalent of an
insulating bushing.
N/A
12.5.2
Ceramic materials and some molded compositions are
acceptable for insulating bushings.
N/A
12.5.3
A bushing molded integrally with the supply cord is acceptable
on Type SP-2, SPE-2, or heavier cord provided it is not less
than 1/16 inch (1.6 mm) thick in the area where the cord
passes through the enclosure.
P
12.5.4
An insulated metal grommet is acceptable as an insulating
bushing if the insulating material is not less than 1/32 inch (0.8
mm) thick and completely fills the space between the grommet
and the metal in which it is mounted.

Output Connections
P
13.1
Output terminals shall not be exposed unless they are used for
Class 2 output circuits.
P
Exception: A power unit may employ exposed terminals if the
terminals are located in an isolated secondary circuit and all of
the following conditions are met:
P
a) The maximum output voltage (Vmax) does not exceed42.4
volts peak ac or 60 volts dc.
60Vdc
P
b) The output current rating does not exceed8 amperes for ac
or dc voltages up to 30 V rms, or 150/Vmax amperes for dc
voltages between 30 V and 60 V.
P
c) The exposed terminals comply with the requirements
in12.2.1 - 12.2.9.
