11.2.3.8 A wiring terminal shall be prevented from turning.
11.2.3.9 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.
Exception: A lead may be less than 6 inches (152 mm) long if it is evident that the use of a longer lead
might result in a risk of fire or electric shock.
11.2.3.10 A wire-binding screw at a field-wiring terminal shall not be smaller than No. 10.
Exception: A No. 8 screw may be used at a terminal intended only for the connection of a No. 14 AWG
2
(2.1 mm ) conductor.
11.2.3.11 A wire-binding screw shall thread into metal.
11.2.3.12 A terminal plate tapped for a wire-binding screw shall be of metal not less than 0.050 inch (1.27
mm) thick. There shall be no fewer than two full threads in the metal of the plate.
Exception: A plate not less than 0.030 inch (0.76 mm) thick is acceptable if the tapped threads provide
equivalent mechanical strength.
11.2.3.13 A terminal plate formed from stock having the thickness specified in 11.2.3.12 may have the
metal extruded at the tapped hole to provide two full threads for the binding screw.
11.2.3.14 Upturned lugs or a cupped washer shall be capable of retaining a supply conductor of the size
indicated in 11.2.3.1 under the head of the screw or washer.
11.2.4 Identification
11.2.4.1 An appliance intended for permanent connection to a grounded power-supply conductor and
employing a lamp- or element-holder of the screw-shell type, a single-pole switch or overcurrent protective
device other than an automatic control without a marked off position, shall have one terminal or lead
identified for connection of the grounded conductor of the supply circuit. The identified terminal or lead
shall be the one that is electrically connected to screw shells of lamp- or element-holders, and to which
is connected no single-pole switch or single-pole overcurrent-protective device other than an automatic
control without a marked off position.
11.2.4.2 A terminal intended for connection of a grounded power-supply conductor shall be of or plated
with a metal substantially white in color and shall be readily distinguishable from the other terminals, or
proper identification of that terminal shall be clearly shown in some other manner, such as on an attached
wiring diagram.
11.2.4.3 A lead for connection of a grounded power-supply conductor shall have a white or gray color and
shall be readily distinguishable from the other leads.
