A couple of questions. I never understood the logic of 3-wire dryer cords where there was a ground strap to neutral jumper on the dryer side.
1- Is there improved safety upgrading a dryer cord from 3-wire to 4-wire?
2- What's the risk if someone didn't remove the jumper or ground strap from neutral to ground at the dryer lugs, when installing 4-wire from a previously 3-wired connection?
