I inspected a house yesteday that had a few GFCI outlets in the kitchen and all the rest of thle outlets in the house were labeled as GFCI with no ground for equipment being used. My tester showed open ground & would not trip any GFCI device.
Ther were also a couple of 2 prong outlets in one bedroom. Is this just a way of converting the house from 2 prong to 3 prong & is it safe or meet code.
The house was built in 1956
