240 v wiring question


I am new to this site, thanks for having me. I am on the east coast where tropical storm Irene destroyed my mom's home. My brother and I did a lot of the work, we did have to get an electrican for a couple things. He was running a line for a new dryer. From the panel he used 10/2 and went to a jct box splice, leaving there using 10/3. The 10/2 black is wire nutted to the 10/3 black. The 10/2 white is wire nutted to the red of the 10/3. The 10/2 ground is nutted to the 10/3 white, and to the 10/3 grd. This means the ground and neutral are tied together, that does not seem right to me. Any insight would be great.

Code violation and extremely poor workmanship. Get him back to do it right. Did he pull a permit? Was it inspected?

240 v wiring question


Jupe Blue, thank you for getting back to me. This sure did not look right to me, is there any danger for wiring it like this, even though it works? I am not an electrician but I do have some good ole common sense. I hope I get some more opinions on this. Thanks again Jupe

Code used to allow it but not anymore, so run 10-3 from the panel to the junction box and do it per code.

Agree with Jupe & Julius. 10/3 should have been used for the entire circuit run. Your electrician should have known this.

240 v wiring question


I wanted to take a moment to say a BIG THANK YOU to all of you who took the time to give me your valued professional thoughts. As I said, I am not an electrican, but just someone who is a "do it your selfer", and wanting to "do it" the correct way. Things were very busy at Mom's house after Tropical Storm Irene". My brother and I, along with a friend, could only do so much. We completely gutted the inside, replaced all new insulation and sheet rock. We did the wiring, except for the 220 v to the dryer. I rewired it myself, taking out the jct boxes and using 10/3 from the panel, to the dryer, as all of you suggested. It's not over with the electrican, but the house is as it should be!! Thank you all so much.....
BE SAFE!!!!!!!!

Julius, codes NEVER allowed 10/2NM cable for a 120/240v dryer.
10/3 w/o ground was allowed, but a white insulated neutral was ALWAYS required, unless you used SEU cable.
