A GFCI without ground wire isn’t ideal, but it’s better than a 2-prong outlet. A GFCI outlet will work without a ground wire and it’s legal. If the outlet shorts out for any reason, it will still trip for safety, even without ground.
What happens if GFCI is not grounded?
If this short circuit occurs and there is no ground wire present, the current could find its way to ground through other building components in the wall, potentially causing a fire. Or, if you were to touch the plug at an inopportune time, the current could find its way to ground through your body, causing a shock.
Can GFCI replace ungrounded outlet?
Answered by Kestrel Electric: You are correct: Replacing all ungrounded outlets with GFCI will elimiate shock and electrocution hazards. It will give you the biggest safety bang for the buck. It will not protect against arching. It will not ground anything.
