23.2.2
A barrier used to provide separation between field wiring of one
circuit and field or factory wiring or uninsulated live parts of
another circuit shall be spaced no more than 1/16 inch (1.6
mm) from the enclosure walls and interior mechanisms,
component-mounted panels, and other parts that serve to
provide separated compartments.

23.3.1
A unit shall be constructed so that a field-installed conductor of
a circuit is capable of being separated as specified in 23.3.2 or
separated by barriers as specified in 23.2.1 and 23.2.2 from:
N/A
a) Factory-installed conductors connected to any other circuit,
where the conductors are not insulated for the field-wiring
voltage rating.
N/A
b) An uninsulated live part of another circuit, and from an
uninsulated live part when short circuit with it results in a risk of
fire, electric shock, electrical energy involving high current
levels, or injury to persons.
N/A
c) Field-installed conductors connected to any other circuit
unless both circuits are Class2 or Class 3, or both circuits are
other than Class 2 or Class 3.
N/A
Exception: A field-installed conductor is not required to be
separated from a field wiring terminal of a different circuit when
the field wiring is insulated for the maximum voltage of either
circuit and both circuits are Class 2 or Class 3.
N/A
23.3.2
Separation of a field-installed conductor from another field-
installed conductor, and from an uninsulated live part
connected to another circuit, is able to be accomplished by
locating an opening in the enclosure for the conductor opposite
to the conductor terminal so that, when the installation is
complete, the conductors and parts of different circuits are
separated by a minimum of 1/4 inch (6.4 mm). In determining
whether a unit having such openings complies with this
requirement, it is to be wired as in service including 6 inches
(152.4 mm) of slack in each conductor within the enclosure. No
more than average care is to be exercised in routing the wiring
and stowing the conductor slack into the wiring compartment.
Provisions for maintaining a minimum 1/4 inch spacing between
field-installed Class 2 or Class 3 conductors and power, light, or
Class 1 conductors are able to be in the form of a marking in
accordance with 61.2.19.
N/A
23.3.3
With reference to 23.3.2, when the number of openings in the
enclosure does not exceed the minimum required for the proper
wiring of the unit, and when each opening is located opposite a
set of terminals, it shall be assumed that a conductor entering
an opening connects to the terminal opposite that opening.
When more than the minimum number of openings are
provided, the possibility of a conductor entering an opening
other than the one opposite the terminal to which it is intended
to be connected and the likelihood of it contacting insulated
conductors or uninsulated current-carrying parts connected to a
different circuit, are to be investigated.
