Let’s Talk About 2-Prong Electrical Wiring
Let's talk about 2-prong electrical wiring! What 2 prong means is that it is missing 1 prong and the one that it is missing is the ground. This kind of wiring is after knob and tube. Overall it is fine, insurance doesn't usually require you to change anything, but there are some modifications you may have to make. That prong that is missing means all your fancy electronics aren't protected.
You have options:
Install GFI's at each outlet
Install GFI's at the panel
Install a ground wire throughout the home
Of course, talk to an electrician to ensure what you are doing is up to code and the right decision, and make sure you have us as your realtors so we can help spot things like this for you!
