14.4 Wiring terminals and leads
P
14.4.1 A field-wiring terminal is a terminal to which a wire is
connected in the field, unless the wire and a means
of making the connection – a pressure terminal
connector, soldered loop, crimped eyelet, or the like
– factory-assembled to the wire, are provided as
part of the appliance.
P
14.4.2
A fan intended to be permanently connected
electrically and rated 12 Amps or less shall be
provided with wiring terminals, including an
equipment grounding terminal,When the fan rating
exceeds 12 Amps, terminals shall be suitable for
125 percent of the current rating of the fan.
P
14.4.3
A wiring terminal shall be provided with an
acceptable pressure terminal connector securely
fastened in place – for example, firmly bolted or held
by a screw.
P
14.4.4
A wiring terminal shall be prevented from turning or
shifting in position.
P
14.4.5
A wire-binding screw at a field-wiring terminal shall
not be smaller than No. 10 (4.8 mm diameter).
P
14.4.6
It should be noted that 14 AWG (2.1 mm2) is the
smallest conductor that shall be used for branch-
circuit wiring, and thus is the smallest conductor that
shall be anticipated at a terminal for connection of a
power-supply wire.
P
14.4.7
A terminal plate tapped for a wire-binding screw
shall be of metal not less than 1.27 mm (0.050
inch) thick. There shall be two or more full threads
in the metal, which may be extruded if necessary to
provide the threads.
P
14.4.8
Upturned lugs, a cupped washer, or the equivalent
shall be capable of retaining a conductor of the
size specified in 14.4.2 under the head of a screw
or washer.
