What is the difference between a 15-amp and 20-amp receptacle? 

Most homes are wired with both 15-amp and 20-amp receptacles. 15-amp outlets have a u-shaped grounding hole and two slots. 20-amp receptacles have a horizontal slot that branches off from the vertical slots. 20-amp outlets work with appliances, such as microwaves, and must operate on a 20-amp circuit.

How do I install a duplex outlet? 

  1. Turn off all power to the outlet from the circuit breaker.
  2. Unscrew and remove the wall plate.
  3. Unscrew and remove the electrical box from the wall with wires still attached.
  4. Remove the wires.
  5. Carefully check the old receptacle and make sure the break-off tab connecting the two terminals on each side is broken off. If it is, remove the tabs from the outlet using a pair of long-nose pliers.
  6. Attach the wires to the terminals of the new electrical receptacle.
  7. Push the new outlet back into the box and screw into place.
  8. Screw the wall plate and turn the power back on.
