10 Shocking Wiring Dangers That Could Set Your Home on Fire!

5. No GFCIs

What It Means: There is a higher risk of electrocution in wet areas, like bathrooms and kitchens, where water and electricity can mix. GFCIs (Ground-Fault Circuit Interrupters) quickly shut down circuits within 4 milliseconds, preventing deadly shocks.

Code Violation? No; it's "grandfathered in." (Current codes require GFCIs in kitchens, garages, basements, and outdoor outlets.)

Danger Level: High.

Solution: Replace old receptacles with GFCIs. This is a relatively simple task that homeowners can often do themselves, or they can hire an electrician. Alternatively, GFCI breakers can be installed in the main electrical panel, but if one trips, you will need to go to the basement to reset it.
