22.3.8
The means of connecting stranded internal wiring to a wire-
binding screw shall be such that loose strands of wire will be
prevented from contacting other live parts not always of the
same polarity as the wire, and from contacting dead metal
parts. This may be accomplished by the use of a pressure
terminal connector, a soldering lug, a crimped eyelet, soldering
of all strands together, or other acceptable means.
No such construction
N/A
22.3.9
An open-end spade lug is not acceptable unless an additional
means, such as upturned ends on the lug, or bosses or
shoulders on the terminal, is provided to hold the lug in place if
the binding screw or nut loosens.

Factory wiring
P
23.1.1
Insulated conductors of different circuits (see 23.1.2) within a
unit, including wires in a terminal box or compartment, shall be
either separated by barriers or segregated and shall be so
separated or segregated from uninsulated live parts connected
to different circuits.
P
Exception: When each insulated conductor is provided with
insulation rated for the highest of the circuit voltages, no barrier
or segregation is required.
N/A
23.1.2
For the purpose of the requirement in 23.1.1, different circuits
include:
P
a) Circuits connected to the primary and secondary windings
of an isolation transformer;
P
b) Circuits connected to different isolated secondary windings
of a multi-secondary transformer;
P
c) Circuits connected to secondary windings of different
transformers;
N/A
d) Input and output circuits of an optical isolator;
P
e) AC input power and output ac power circuits;
N/A
f) AC input power and dc power circuits; and
P
g) AC output power and dc power circuits.
N/A
Exception: Power circuits specified in (e), (f), and (g) that are
derived from the taps of an autotransformer or similar
components which do not provide isolation are not different
circuits.
N/A
23.1.3
Segregation methods which satisfy 23.1.1 include clamping,
routing, or an equivalent means that maintains permanent
separation from insulated and uninsulated live parts and from
conductors of a different circuit.
P
23.1.4
An insulated live part is able to touch any insulated or
uninsulated live part of the same circuit when one of the live
parts is insulated for the higher potential.

used
N/A
23.2.1
A barrier used to provide separation between the wiring of
different circuits shall be mechanically supported and reliably
held in place to prevent displacement, and it shall be:
N/A
a) Grounded metal with a minimum thickness as specified for
small surfaces in Table 7.1; or
N/A
b) Insulating material complying with 35.3.1 of such thickness
such that deformation does not occur to defeat its purpose.
