Make Tight Wiring Connections

Electricity travels along conductors, such as wires and the metal contacts of outlets and sockets. Tight connections between conductors create smooth transitions from one conductor to another. But loose connections act like speed bumps, restricting the flow and creating friction and heat. Very loose connections can lead to arcing, in which electricity jumps through the air from one conductor to another, creating tremendous heat.

Prevent fire hazards by making sure all wiring connections are tight and have full contact of the conductors being joined. When splicing wires together, always use approved wire connectors (“wire nuts”).
