Exception No. 1: A No. 8 (4.2 mm diameter) screw may be
used at a terminal intended only for the connection of a 14
AWG (2.1 mm2) conductor.
N/A
Exception No. 2: A No. 6 (3.5 mm diameter) screw may be
used for the connection of a 16 AWG (1.3 mm2) or 18 AWG
(0.82 mm2) control-circuit conductor.
N/A
12.2.6
A wire-binding screw shall thread into metal.
N/A
12.2.7
A terminal plate tapped for a wire-binding screw shall be of
metal not less than 0.050 inch (1.27 mm) thick.
N/A
Exception No. 1: A plate not less than 0.030 inch (0.76 mm)
may be used if the tapped threads will not strip when subjected
to the tightening torque specified in Table 12.1.
N/A
Exception No. 2: A plate less than 0.030 inch (0.76 mm) thick
may be used in a Class 2 circuit, Class 3 circuit, or an isolated-
limited-energy circuit if the tapped threads will not strip when
subjected to the tightening torque specified in Table 12.1.
N/A
12.2.8
There shall be two or more full threads in the metal of a
terminal plate. The metal may be extruded at the tapped hole to
provide at least two full threads.
N/A
Exception: Two full threads are not required for a terminal in a
Class2 circuit, Class 3 circuit, or an isolated limited-energy
circuit if a lesser number of threads results in a secure
connection in which the threads will not strip when subjected to
the tightening torque specified in Table 12.1.
N/A
12.2.9
Upturned lugs, a cupped washer, or the equivalent shall be
capable of retaining a conductor of the size specified
in 12.2.5 under the head of the screw or washer.
N/A
12.2.10
The free length of a lead inside an outlet box or wiring
compartment shall be 6 inches (152 mm) or more if the lead is
intended for field connection to an external circuit.
N/A
12.2.11
With reference to Exception No. 2 to 12.2.3, a pressure
terminal connector is not required to be provided with a wiring
terminal when the following conditions are met:
N/A
a) A terminal assembly shall be either:
N/A
1) Supplied by the manufacturer - installed or shipped
separately; or
N/A
2) Specified in a marking on the power unit in accordance
with 61.2.15 and 61.2.16.
N/A
b) A fastening device, such as a stud, nut, bolt, spring or flat
washer, or similar device, as required for an effective
installation, shall either be provided as part of the terminal
assembly or be mounted on or separately packaged with the
power unit.
N/A
c) The installation of the terminal assembly shall not involve
the loosening or disassembly of parts other than the cover or
other part giving access to the terminal location. The means for
securing the terminal connectors shall be readily accessible for
tightening before and after installation of conductors.
N/A
d) When the pressure terminal connector provided in a
terminal assembly requires the use of a special tool for
securing the conductor, any required instructions shall be
included in the assembly package or with the power unit.
See 61.2.17.
