The benefit to locating the PFC caps close to the NST rather than in a
remote controller enclosure is that current, and hence voltage drop along
the mains cable between the controller & NST, will be less.  This may buy
you a few more volts to the NST and may be significant.  As far as what
your circuit breaker sees, it won't matter where the PFC cap is.

Gary,

On a slightly related issue, does it matter where the PFC caps are located?
 I've run out of real-estate under the coil so I plan to stuff them into
the controller enclosure.  In fact, couldn't they be attached anywhere on
the power leg that feeds the nst?
