TERMINALS
....
Terminals of the wire-binding screw, setscrew, or screw-actuated back
wired clamping types are suitable for use with both solid and stranded
building wires.
Screwless terminal connectors of the conductor push-in type (also known
as ??push-in-terminals??) are restricted to 15 A branch circuits and are for
connection with 14 AWG solid copper wire only. They are not intended for
use with aluminum or copper-clad aluminum wire, 14 AWG stranded copper
wire, or 12 AWG solid or stranded copper wire.
Single and duplex receptacles rated 15 and 20 A that are provided with
more than one set of terminals for the connection of line and neutral conductors
have been investigated to feed branch-circuit conductors connected
to other outlets on a multi-outlet branch circuit, as follows:
- Back wire (screw actuated clamp type) terminations with multiple wire
access holes used concurrently to terminate more than one conductor
- Side wire (binding screw) terminals used concurrently with their
respective push-in (screwless) terminations to terminate more than one
conductor
Single and duplex receptacles rated 15 and 20 A that are provided with
more than one set of terminals for the connection of line and neutral conductors
have not been investigated to feed branch-circuit conductors connected
to other outlets on a multi-outlet branch circuit, as follows:
- Side wire (binding screw) terminal with its associated back wire (screw
actuated clamp type) terminal
- Multiple conductors under a single binding screw
- Multiple conductors in a single back wire hole
Duplex receptacles rated 15 and 20 A that are provided with break off tabs
may have those tabs removed so that the two receptacles may be wired in a
multi-wire branch circuit
