if there is no ground wire in outlet box can i use a gfci?

[johnnyfalcon]

Would a gfci ground my outlet?

Im guessing this outlet can only be truley protected with a surge protector?

A GFCI will absolutely work without a grounding conductor. A GFCI measures any current difference between the live and neutral wires. If they don't match, current is going somewhere it isn't supposed to and it trips. It doesn't require a ground to do that.

Its a waste using a gfi on a 2 wire system. A standard outlet will work fine as long as its on a breaker. The outlet should match the wire size rating. 15 amp or 20 amp. The breaker needs to be matched too. You dont want a 20 amp breaker on #14 wire.
