I've done some searching on this already and I think I know the answer. But I'd like to ask just to double check.
If i am not sure if the outlets are properly grounded, my best bet would be to replace the 2 prong outlets with GFCI outlets, correct? Actually, i suppose someone is going to say my best bet would be to first find out for sure if they are properly grounded or not :) Could someone suggest a relatively inexpensive tool for doing that?
If the boxes are correctly grounded, then I should be able to just replace the 2 prong outlets with regular 3 prong outlets, correct?
For right now, I mainly want to swap out a 2 prong outlet in the living room that the TV and the rest of the media/gaming stuff will be plugged in to. But there are 2 prong outlets scattered around the house that I'll probably also want to eventually replace.
I would be somewhat surprised if everything is correctly grounded since the wiring in the house is pretty old, it's all knob and tube wiring. Although the home inspector said it all looks like it's in pretty good shape. Eventually we'll have an electrician come in and replace all the wiring, but for now it's staying as is.
