* Improperly installed electrical wires could burn the wire
connectors.
Make sure to firmly tighten the
wire connectors for a secure
connection. A loose connection
can be a fire hazard.
To install wire connectors,
you must:
Insert the two wires into the wire nut so that their
copper ends are parallel.
Turn the wire connector clockwise until there is
strong tension.
Pull on the threads to make sure they are secure,
leaving no gaps between them. * If the threads
seem to come loose, repeat the process.
