I am changing a four prong dryer cord to a three prong cord. My problem is the lack of a ground wire on the new three prong cord. I saw the instructions online, it explained about the grounding plate & the #10 wire. Well, when I went to Lowe's an employee there told me it was unnecessary. She said she was educated in electrical things & assured me she knew what she was talking about. So which is it? Do I have to ground it to the body of the dryer, or can I just hook the new three prong cord up and roll with it?
You may believe a Lowes sales person who is "educated in things" or you may believe an electrician with 20 years of practical experience that has read and understood the electrical code of the US as well as what grounding does and why it is necessary. Your choice: should you choose experience and understanding of electricity then put the ground strap in as described.
I did not provide explicit directions and photos for a grounding wire because it looks pretty; I did it because grounding is necessary for safe operation of your dryer and is required by law.
