How to Prevent Electrical Arcing

Extension or appliance cords that are damaged or have worn or cracked insulation can contribute to electrical arcing.

Cables that are improperly nailed or stapled too tightly against a wall stud can sever insulation and cause arcing.

Nails carelessly driven into walls can break wire insulation and cause arcing.

Wires located behind walls can be accidentally punctured by a screw or drill bit damaging the insulation of the wiring.

Cord insulation can be deteriorated by heat generated by hot air ducts or sunlight.
