I had an electric outlet not working in my kitchen. I tested if the power was still coming in the terminal and it was. Then I turned off the power and installed a new outlet. However it was a 20 A. When I plugged in the power, the appliances beeped and then stopped. I then found the issue and removed my 20 A outlet to reinstall the 15 A outlet. However there is no power through the black or the white wire now. I checked the trip switch and turned it off and on a couple of tims. Still it is not working. Any help would be greatly appreciated.
