Two-prong outlets usually mean the circuit has no ground wire. You have three safe options: run a new grounded circuit or ground wire, install GFCI protection and label the outlets “No Equipment Ground,” or leave them as two-prong outlets. What isn’t safe is swapping in a three-prong outlet with nothing connected to the ground terminal. It looks grounded but isn’t, and that can give a false sense of protection for computers and appliances that rely on a ground.
Option 1: Add a ground or rewire
A licensed electrician can run a new grounded circuit, or in some cases add a ground wire back to the panel. This is the most complete fix and is the best choice for outlets that feed computers, TVs or equipment that needs a true ground. See wiring and rewiring.
Option 2: GFCI protection
A GFCI outlet, or a GFCI breaker at the panel, can protect ungrounded outlets against shock. Three-prong outlets on that circuit are then allowed if they are labeled “GFCI Protected” and “No Equipment Ground.” A GFCI protects people but doesn’t provide a ground for surge strips or equipment. See GFCI protection.
Option 3: Keep two-prong outlets
Existing two-prong outlets in good condition can stay. Replace damaged ones with new two-prong outlets, and don’t use “cheater” adapters to plug in three-prong cords.
Check the bigger picture
Homes with two-prong outlets are often older homes that may also have small panels, knob-and-tube or aluminum wiring. We look at the whole circuit before recommending a fix, and the work is done under permit where required.

Frequently asked questions
Can I just put a three-prong outlet in place of a two-prong outlet?
Not unless the circuit has a ground or the outlet is GFCI protected and labeled “No Equipment Ground.” An ungrounded three-prong outlet without GFCI protection is unsafe.
Is a GFCI as good as a ground?
It protects people from shock, but it doesn’t give equipment a ground path. Sensitive electronics are better on a grounded circuit.
Do two-prong outlets mean I need to rewire?
Not necessarily. GFCI protection is often an accepted option. An electrician can tell you what fits your home.
Are two-prong adapters safe?
No. “Cheater” adapters defeat the grounding pin and shouldn’t be used.
