I have moved into an older home. All of the outlets are two prong only. Is there an extension cord that will plug into the wall with a 2 prong, but has 3 prongs in the extension part? If not, how am I going to make things work in this old place, lol?? Thank you for any help!
You can legally change the outlet, as long as it is “GFCI Protected” and marked “No Equipment Ground". You'll get the safety benefits of a third wire ground, though not all the surge protection benefits of your power strip. The GFCI units do use some 'vampire' power, about 1 Watt, 24/7.
Section 406.3(D)(3) of the 2008 National Electric Code covers this situation.
Consider also a whole house surge protector, and if you have K&T wiring, an AFCI on the K&T. That said, if any of this sounds unfamiliar, hire a home inspector to check out everything and provide advice as to priorties.
