So, I'm planning to do a EBIAB in my laundry room, since I already have the 30A hook up. My question is....my dryer is currently hooked up with a 3 prong outlet. I took the receptacle off the wall, and saw that there is a ground wire ran to it. I'm planning to put a 4 wire receptacle in for the EBIAB, but what should I do about the dryer? I assume I will have to upgrade to the newer 4 prong dryer plug, but what do I do with the ground going to the dryer? I've read that most are grounded via the frame? Do I just hook up the two hots and neutral as normal, then ground the ground wire to some place on the frame of the dryer?
Also, I would assume that the ground wire used for the dryer is actually grounded at the main panel, but is the best way to check, by taking the panel front cover off and just making sure the ground goes to the grounding strip?
