Megawatt Inrush And Small Generators
In the interests of accuracy I have copied John Marles, comments verbatim and they appear below "Inrush is 50A/115VAC 50A/230VAC for a few milliseconds on the S-400 and S-350. Its controlled by due...

I think i know what he is saying
The cap goes across the megawatt input,
It will be charged when you hold the pushbutton switch closed
It will be charged at the RMS voltage level
It is not going to go from zero to 178 back to zero
The stored RMS 120v will add Momentary starting current to input/, induction circuit of the mega watt, allowing a small generator to energize the circuit and charge batteries
It's not the 700w charging that stops an 800w generator, it's the inrush current very similar to starting an induction motor like a compressor
Since a run cap is designed to be left in the circuit, using it as a momentary start cap will not hurt it, and if needed , it could be hard wired to the mega watt and left in the circuit,
The input of the megawatt becomes an LC load circuit, not just An L load
