I have question about the AFCI breakers as a fix for two prong outlets. The fact that there is no physical ground wire from the NEW three prong outlets back to the main panel ground, will the AFCI protect three prong appliances plug into them from surges, spikes, or static electrical charges? Flat screen tv’s, computers, gaming systems and the like are all very sensitive to over current issues. These would normally get shunted to ground, but with no ground wire, how can they protect?? This is why (I believe) the IEC states that the out outlet should be labeled as “Non-Grounded Outlet”.
For example, the ground wire in a plug is connected to the metal casing of a PC desktop. If the hot lead somehow comes in contact with that metal casing and then a person touches the casing, they would complete the circuit to ground.
