@jea48 , just called the electrician that my dealer directed me to. Very glad you explained the difference in cables to me, thank you! Electrician immediately assumed I would want BX. I explained that no I need the separate ground wire and the electrician said “ah you need the insulated green with the metal clad” and he said that made total sense for the application, so that each device has their own connection to our house’s ground. So thanks again for clarifying that or I wouldn’t have known.
He also said he understood the need for heavier gauge solid core wire to support instantaneous current availability, which he said would be particularly important for longer runs like what I need.
Glad I started this thread or I may have ended up with the wrong wire!
He is coming by in a week or so to provide an estimate.
