Older 2-slot receptacles should be replaced by 3-prong receptacles when they fail, but first make sure the outlet is grounded. If it is not grounded, call an electrician to update the outlet.	Grounded receptacles contain two vertical slots and one round slot. Choose a replacement receptacle with the same amp, volt and wire gauge ratings as old receptacle.

GFCI receptacle senses tiny changes in current and shuts off power before shock can occur. GFCI is installed in the same way as standard 3-prong receptacle. Test GFCI once a month: press test button. Reset button will pop out if receptacle is operating properly.	Step One: Turn off power to outlet at main service panel. Remove coverplate. To test for current, carefully touch probes of circuit tester to top screw terminals on sides of receptacle. Repeat on bottom screws. If tester does not light, wires are safe to touch.

Step Two: Loosen mounting screws, then grip mounting strap to carefully pull receptacle from box. Use small tabs of masking tape to note where each wire is attached to receptacle.	Step Three: Release push-in connections by inserting tip of small screwdriver into release slot; or loosen screw terminals and remove the receptacle from wires.

Step Four: Choose replacement receptacle with same ratings as old receptacle. Attach wires to receptacle using tape markings as a guide.	Step Five: Connect the bare copper or green insulated wire to ground screw terminal. If box contains two ground wires, attach a green pigtail wire to the ground screw, then connect pigtail to both ground wires with a wire nut.

Step Six: Push receptacle back into box, carefully tucking in wires. Tighten mounting screws and attach coverplate.
