I'm about to move into an older home at the end of the month. Upon inspection, the inspector found that the outlets aren't grounded. I've been doing a lot of reading on how to fix the situation. I understand that my options are to 1. Ground the outlets. I can do this easily but there are a lot of outlets. 2. Install GFCI outlets and ground them. This is expensive but I'm not really worried about that. 3. Install GFCI or GFCI/AFCI breakers in the electrical panel.
I'm leaving towards option 3. I keep reading that I can do option 3 depending on my homes wiring. There was no elaboration on what wiring my home needs to make sure that GFCI breakers will offer the protection that I need. Is it just as simple as replacing old breakers with GFCI breakers and grounding them on a ground bar (I forget the actual name of the bar) or will I have to run additionadditional wiring all around the house in addition to installing the GFCI breakers? The house was built in 1952 and had a new panel installed but uses what looks like nonon GFCI breakers. Any help or a link to better reading material?
