Wiring Methods When Replacing Outlets

Electrical Question: I am trying to replace a 2 prong recepticle with a 3-prong receptacle.

  • The existing wire is 12-2, I removed the old outlet and installed a new one ,connected the wires and the ground.
  • When I turned the power on my detector sensed power throughout the whole receptacle but when I plugged into the outlet I could not get power through the outlet into the device I plugged in. ( device aka shop-vac).
  • What did I do wrong and is there a way to correct it?

This electrical wiring question came from: Richard, a Homeowner from Coplay, PA.

Thanks for your electrical wiring question Richard.

How to Wire Replacement Electric Outlets

  • Types of Outlets
    • Receptacle outlets should be replaced with the same type, and the same voltage and amperage rating.
  • 2-Wire Outlets and 3-Wire Outlets
    • Three wire outlets should not be installed if a ground wire is not present, two wire receptacles may be purchased and installed instead.
  • Outlet Wiring Connections
    • Wiring connections should match what was found on the original outlet. Only one wire is to be  used per screw terminal.
  • Outlets that Trip a Circuit Breaker
    • If the circuit is tripping the circuit breaker then the wiring connections and installation methods must be checked and verified.
