I'm not sure what a lighting cap is, but if it's rated for continuous AC 
duty, there's no reason to think it would have any trouble.  There's 
nothing particularly stressful about a PFC cap application, even for a 
Tesla coil, so there's no reason to overspec an AC capacitor's voltage 
rating.

However, do not connect the case of the PFC cap to any ground, RF or 
mains.  If you've got a good EMI filter between the cap and the NST you may 
be able to connect the cap case to mains ground.

Hi All,

I am going to get some pfc caps and I have a choice on getting 450v
motor run caps and 240v lighting caps.

I think the 240v ones are cheaper.  The psu will be drawing about 20
amps initially.  Will the lighting ones survive this?


Regards,


Justin.
