While updating some electrical in my home, it was discovered that some of the outlets were 12/2 wiring with 15 amp outlets. I decided to install the proper 20 amp outlets to those receptacles.
Of course I turned off the breaker to the outlet, then tested with one of those plug in testers..no lights. However, once I removed the plate and pulled out the outlet, I tested again with a voltage tester. There are 2 black wires, 2 white wires and the grounds. The white wires were still hot. I found the other circuit and turned it off. I'm just questioning why and/or if this is ok to wire back as is.
For the record, it is apparent someone previously, in an effort to appear updated, went around and replaced a majority of the switches and outlets and even added green ground wires in some receptacles. Obviously not aware of wire gauge or the function of the wiring.
1 outlet on 2 circuits
