Grounded conductor has to be covered not bare except for se cable. I just had a problem with a dryer I went to troubleshoot. It was a 10/2 feeding the recep & the grounding conductor was used as the 120v potential for the timer loads, Lts. etc; As I had the recep out, I plugged in the dryer & I lost one les and picked up 240v on the other. There is a break in the grounding conductor somewhere. I have to run a 10/3 now & change unit to a 4 prong whip. I'm glad the code wants the noodl & EGC separated.
