I'm in NY. We're replace an existing dryer. It is hardwired. A cable is coming from the dryer to a steel utility box. The cable coming from the wall is black with a black and white cable with a copper ground cable coming from it. They connect within the steel utility box to the dryer cable. I understand I need to have a receptacle added. Do I add a 4 or 3 conductor receptacle?
Thanks
