MN> You are right, Richard. That is a lot of 440VAC rated caps.
MN> I was just looking at them today in the C&H catalog. I'm
MN> envisioning a disconnect box that I can plug into the dryer
MN> outlet. The one I have is on a 30A breaker.
Yes this is exactly the kind of service I would look for. Though
some will scream about supposed code violations, you can upgrade
the breaker in the box to a 50 amp here without much problem.
Every code 240 volt household service wiring that I have looked
at was much heavier duty than the intended load. I am not saying
that you can, or should, abuse the code wiring. What I am saying
is that a Tesla coil is not operating with the same duty cycles
as a dryer, stove, or air conditioner. I run several sets of
circuit protection in all of my Tesla supply wiring, and I watch
my power draw on a meter. With proper loading, circuit pro-
tection, and metering, I am not worried about cooking or
overloading a circuit.
MN> I have one 60ma and two 30ma 12000v neons. Would it work to
MN> parallel the two 30ma's together and then series that pair
MN> to the 60ma? Sounds hairy.
Sounds hairy, but it will probably work fine once you get
everything phased correctly.
MN> Think I will look for another 12K/60 just for simplicity.
MN> Are pfc caps in series or parallel to the neon primary?
Parallel. The capacitance is placed across the line as close as
possible to the neon primary coil.
MN> And if I needed 140-145uF with 120VAC, What do I need with
Divide by four. You will need 35 uF or so of pfc capacitance at
MN> So much to learn.
So much to burn!
... If all else fails... Throw another megavolt across it!
