Hello, I have dryer hookup question. I purchased a new dryer, and I hired an electrician to replace the old 1950ís three wire outlet with a four wire outlet. He recommended not replacing the existing wiring, and that the conduit that runs from the outlet to the panel could be used as the ground, so there was no need to run a separate ground wire.
When he connected the new four wire dryer cord to the appliance, he attached the green ground wire to the metal frame along with the yellow/green wire. Now comes the question, should the yellow green wire be attached to the frame as well, or should it be connected to the Neutral post? There is no ground wire going from the outlet to the panel, so this configuration seems correct. What do you guys think?
Thank you for the help. Iíll ask him if he tested the integrity of that conduit as a grounding path. If the answer is no, Iíll ask him to run an additional EGC to be safe. This site is a great resource. Thanks again
