I knew there would be inrush current to the capacitors, but I didn't realize that the transformer, in and of itself, would have an inrush current. Guess that shows how much I know!
I was planning to use one or more motor run capacitors to limit inrush current - use a relay in parallel with the cap, and close the relay a few seconds after applying power. Now that Jon brought it up, I think I will visit the local junkyard instead.
