An uninsulated section of a single conductor
should not be looped around the terminal and
serve as two separate connections. The wire
must be severed, thereby providing supervision
of the connection in the event that the wire
becomes dislodged from under the terminal.
Typical Connections
Break out thin section of divider to
provide path for wires when wiring both
switches from one conduit entrance.
