Do surge protectors work to protect electronics when there is no ground wire in wall outlets? Our house was built in 1911. Most of the electrical is original knob and tube. No ground wire on 3-prong outlets (though many outlets are still two-prong). Can a surge protector really protect our electronic equipment if there is no ground? If not, is there any way to protect our stuff?
