Older Homes Have More Wiring Worries

Homes that are more than two decades old could have electrical problems, leading to power failures, fires, or electrical shocks. Worn wiring, overused extension cords, and inadequate circuits are the most common problems, according to the Copper Development Association.

However, there are several other defects that could be uncovered by licensed electricians. Wiring that is too small for electricity to flow freely, for example, can get too hot and start fires. The problem is exacerbated in attic areas, so homeowners would be wise to ensure that wiring in that space is large in diameter.

Owners of homes with aluminum wires, which are more brittle and corrosive than copper wires, can either completely rewire the residence or, as a much more affordable alternative, attach copper wire near outlets and switches.

Additionally, they should make sure fuses are of the appropriate rating and consider installing ground fault circuit interrupters (GFCI) and arc fault circuit interrupters (AFCI). GFCIs minimize the risk of electric shock in kitchens, bathrooms, and other moist spaces; while AFCIs safeguard against fires caused by arcs in worn cords.
