Our house was built in the 50s and hasn't had wiring updated to 3-prong outlets. The current wiring is not the knob and tube kind. We checked into getting the house rewired and that's way out of the budget. It seems much more cost-effective just to install the GFCI outlets. However we aren't sure about the amps and volts that are needed. How do we figure out how to select the proper outlet for our house? via /r/DIY http://bit.ly/2Qxqj0c
