12.2.2.2 Any of the terminal configurations listed in 12.2.1 may be used for connection of field wiring if there is compliance with all of the following:
a) If a special tool is required for connection, its use shall be indicated on the installation wiring diagram and the name of its manufacturer and its model number or equivalent shall also be
indicated, along with information as to where the tool may be obtained.
b) The range of wire sizes shall be indicated on the installation wiring diagram. The minimum permissible wire size is 22 AWG (0.32 mm2).
c) The wire size to be used shall have the current-carrying capacity for the circuit application.
d) The terminal configuration shall comply with the requirements in the Special Terminal Assemblies Tests, Section 52.
Exception: Terminals complying with the requirements in any of the standards specified in 12.2.1.2 are not required to be subjected to the Special Terminal Assemblies Tests, Section 52.
12.3 Field wiring leads
12.3.1 If leads are provided in lieu of wiring terminals, they shall be a minimum of 6 inches (152 mm) long, and the minimum permissible wire size shall not be smaller than 22 AWG (0.32 mm2).
Exception No. 1: A lead may be less than 6 inches in length if it is evident that the use of a longer lead:
a) May result in damage to the lead insulation or product;
b) May result in a risk of fire, electric shock, or injury to persons; or
c) Is not required for the intended operation of the product.
Exception No. 2: Solid copper leads as small as 26 A WG (0.13 mm2) may be used if:
a) The current does not exceed 1 ampere for lengths up to 2 feet (61 cm) and the current does not exceed 0.4 ampere for lengths up to 10 feet (3.05 m),
b) There are two or more conductors and they are covered by a common jacket or other covering that has been determined to be equivalent,
c) The assembled conductors comply with the requirement of 42.3 for strain relief, and
d) The installation instructions indicate that the lead shall not be spliced to a conductor larger than 18 AWG (0.82 mm2).
12.3.2 Leads intended for connection of a line voltage source shall not be smaller than 18 AWG (0.82 mm2).
12.3.3 Leads intended for connection to an external circuit shall be provided with a strain relief if stress on the lead may be transmitted to terminals, splices, or internal wiring. See the Strain Relief Test, Section 49.
12.4 Polarity identification
12.4.1 In a product intended to be connected to a grounded circuit, one terminal or lead shall be identified for the connection of the grounded conductor. The identified terminal or lead shall be the one connected to the screw shells of lampholders and to which no primary overcurrent-protective devices or other switching devices of the single-pole type are connected.
12.4.2 A terminal intended for the connection of a grounded supply conductor shall be made of or plated with metal that is substantially white in color and shall be distinguishable from the other terminals, or identification of the terminal shall be clearly shown in some other manner, such as on an attached wiring diagram. A lead intended for the connection of a grounded power-supply conductor shall be finished to show a white or gray color and shall be distinguishable from the other leads.
