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

9. Ungrounded (2-prong) Receptacles

What It Means: Your home's wiring lacks a safe way to conduct stray current if it escapes the wires, which is a critical safety feature.

Code Violation? No; it's "grandfathered in." Current codes require grounded circuits and receptacles.

Danger Level: Minimal, as long as you don't use an adapter to plug a three-prong device into a two-prong receptacle. Doing so can damage the device and increase the risk of electrocution.

Solution: If the wiring permits, replace two-prong receptacles with properly grounded three-prong ones. Use a GFCI circuit tester to check all existing three-prong outlets to ensure they're grounded, and rewire any that are not.
