Rpc (rotary phase converter)blowing caps

I have a rotary phase converter running a 3 phase DSLB. I keep going thru capacitors (initially they get hot 240f- eventually around 400+f and eventually they pop)and having hard time figuring out why.

Bottom right is newest capacitor to start going

What’s your amp load on each phase when running? Could be significantly out of balance

HI,
I’m with @greenbuggy here, check how your phases are balanced in the panel. If that is the case and you do get it fixed you will see some good energy savings as well.

Checking soon as I get back in lab tomorrow. Could make sense my energy bill is pretty crazy running that thing.

The amperage during load was
14.9
16.3
6.8

Voltage
229
218
206
