What Does 2-Prong Electrical Wiring Mean?
Let's talk about 2-prong electrical wiring!
What 2-prong means is that it is missing 1 prong and that 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:
Instal GFI's at each outlet
Instal GFI's at the panel
Instal 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!
