Mike, you are correct. I dug into the available paperwork and confirmed that the headers have a dielectric withstand voltage of 1.5kV and the header receptacles have a DWV of 1kV. The working voltages are not specified. 

You have raised a great concern! That’s why it is fun to work on these custom designed parts. I only have formal experience in low voltage PCBs, and so these give me some exposure to additional considerations with high voltages. I will reach out to Amphenol to see if they have defined working voltages. If not, I’ll research other headers.

My design currently uses these headers and receptacles:

Rod, I’m of English and Irish descent. Several generations have been in the states, though. In fact, the Blasdel family have great documentation on the family tree. Ralph Blaisdell (1593-1649) was the first to immigrate to the states as a wool textile merchant. The name Blasdel comes from St. Blaise, the patron saint of wool combers. 

Anyway, I suppose you’ve lost me on the comment about it getting off the ground.
