400 Hz wiring

I

I said I would not derate ampacity on wire of this size because of it being 400 Hz. You still have to derate for number of CCC. I dont have my spreadsheet handy but I dont think being 400 Hz significantly affects conductor ampacity until the wire size gets to be pretty big. Like #6.

I see what you mean. It is clear now. Thanks

I'm really curious now: what are the loads?

The only job I ever wired for 400Hz was a building for working on flight equipment.
