For a Halloween exhibition, 10 awg is fine. No need to go bigger for
this type of fun with a coil. As far as the caps, I've seen them offered
somewhere before, but I'm not aware of anyone using them in TC service.
Experiment before hand. They may work out great. Keep an eye out for
heat. Try a 30 second run, check for heat, and if cool, your good to go
within reason (maybe then do a 1 minute run). If they get warm, then
just reduce your time on. For low cost caps, you can't go wrong. Who
knows, maybe these caps will handle TC service in long runs like the CD
caps (kind of doubt it, but only testing will reveal the truth).
