Question 1

Can I replace a two-prong outlet with a three-prong?

Accepted Answer

Only with GFCI protection if there's no ground wire. The GFCI provides shock protection even without a ground. Label it "No Equipment Ground."

Question 2

Why does my outlet spark when I plug something in?

Accepted Answer

Small sparks can be normal as current starts flowing. Large sparks, burning smell, or discoloration means replace the outlet immediately.

Question 3

What's the difference between GFCI and AFCI?

Accepted Answer

GFCI protects against shock (ground faults). AFCI protects against fire (arc faults from damaged wiring). Different dangers, both important.

Question 4

My outlet tester shows "open ground." What does that mean?

Accepted Answer

The ground wire isn't connected. The outlet works but doesn't have full protection. Worth fixing, especially if you plug in computers or sensitive electronics.
