PV Wire - 7 or 19 Stranded, Code or Manufacturer Requirements to observe?
Apparently we are the only contractors using 19 stranded wire. I know initially there was some controversy from a well versed code guru electrician of ours on the requirement of a connector we use frequently, perhaps it was mc4, and it not being able to be used with 7 strand. Or perhaps it was something about the characteristics of the copper being 19 stranded, a more theoretical approach. I don't know, and don't remember.
Anyone care to shed some light on why or why not to use either 7 or 19 strand wire. We do use many different connectors as well, not just mc4.
Thanks in advance for weighing in.
