I have an older home with older (non-grounded) wiring. I need to replace a switch/outlet that appears to be defective, but all the switches/outlets i can find at Lowe's or the local hardware store are for grounded connections...no switches just for black and white.
It is ok to use the grounded swithces/outlets with the older wiring...correct? I connect the positive and negative wires to the + and - connections - just ignore the grounding.
