I have a ground wire in the dryer power cord that wasn't used previously. Do I need to use it for grounding?

Question

My outlet is a three prong outlet. Can I use the new dryer's ground strap or should I use the ground wire in the power cord? The previous owner cut the ground wire shorter than the other three so it was covered by the plastic wrap around the cord and he used the ground strap on the old dryer.

Answer 1

If your outlet has a 3 prong then your pigtail(cord) middle wire goes to the center post and the other two wires hook on either side. No need to mess with the ground wire on the dryer leave it connected to the green ground s***w on the chassis.

Answer 2

Code says that you need to use the ground pin in the power cord. That means a four prong outlet. The ground is there to prevent injury if a short circuit should develope in the dryer.

It is safer to do that. However, we went without that ground connection for many decades and very few people were injured. It is taking a chance, so it is your call.

Personally, I would put in the newer outlet, by running and additional wire for the ground. One reason for my choice is that I don't pay for labor. Another is that is is a selling point for the house. Finally, it is safer and if there is any question, you did it right.

Answer 3

on a three prong hook the ground to the center of the three wires (neutral)

the black and red wires should be on either side. but the ground strap works just as good
