20 amp gfci to a 15 amp circuit
I'm wanting to replace a regular outlet with a gfci out. I have a 20 amp gfci but the curcuit breaker is a 15amp breaker with 14/2 wire. Can I still use this gfci or do I need to get a 15 amp gfci? Would it be a fire hazard if I used the 20 amp gfci?

Yes.

In theory someone could plug in a 20A load.

If it is really a 20 amp GFCI (one slot will be the shape of a 'T'), then no. Someone could plug in a device rated for 20 amps (such as a large air conditioner) and overload the circuit.
If it is actually a 15 amp outlet (just the two parallel slots and ground), but is rated for 20 amps "feed-through" (ie.-downstream loads), then you can use it on a 15 amp circuit.

Most GFCI receptacles are 15 amp receptacles, but rated for 20 amp pass through protection.
If the GFCI receptacle you have will accept a 20 amp plug then you need a different receptacle. otherwise you can use the receptacle, assuming you are in the US and there is no local code stipulating otherwise.

It must be a 15 amp because it only has the two parallel slots(no t slot) but it says 20amp 125v on the side of it. Why is that?? Thanks for the info.
