This particular line of reasoning
This was brought up and this inspector was having none of it. He was bringing up the lack of 600v rated control wire in factory supplied UL stamped panels.

We got the super expensive wire that made him happy and moved on with our life.

Thanks Maxburn for reading my post and clarifying.

And also much appreciated this forum discussion about these products with their rating - I have the Belden white paper about this product in my file collection.
