    Default Two to three pronged outlets

    I just bought an older home built in the 1940s, 1945 I believe. While I think the electrical box is fairly new, all of the outlets in the home are two pronged. I would like to have some three pronged outlets for my electronics and appliances. When I had the home inspection done, the inspector mentioned there was a way you could covert the outlets to three pronged in my state, MN, that was legal. Right now I'm using adapters where I need them, but would like to convert some of my outlets to three pronged. Are there any disadvantages to this or is there something I should know? How much would this cost me? Lastly, as long as I've got you here, how much would it cost to re-wire my house ballpark? I don't have the money right now, but some day down the road I may do it. My home is a one and half story with about 900 sq ft. Thanks for any help.

    Electronic equipment with a 3 pronged plug needs the ground. One way is to run a ground wire to the outlet box if there is none already there. You can legally install GFCI outlets with a sticker that says "No Ground" .but it will not provide the noise filtering needed by some equipment.

    Changing the outlets will not get you the grounding you are looking for or want / need.

    Start by chatting with a few electricians in your neighborhood. For recommendations, ask your local building inspectors, angies list, or a few large electrical supply stores. We can't tell you pricing from here. I can't see your house, even if I stand on my chair.

    The best idea is to upgrade your wiring by adding a ground wire from the panel to every outlet and into the ground via a grounding rod.

    Ditto what they all said.

    Cost to rewire a 900 sq ft house will probably run about $4000. A little less if all the sheet rock is removed.

    Best to get three estimates and pick the middle one.
