Look at the Japanese companies, like Mitsubishi. Was helping install a motor drive cabinet that had 6 Mitsubishi inverter drives in them, and all craftsmanship on the panel was perfect. You would hope so, in a cabinet that has 0.72F of power supply capacitor, and almost another entire rack of contactors, timers and power resistors, that are there only to provide the 3 phase rectifier, power control and inrush limiting, with another fan cooled cabinet on top that has the braking resistors for the voltage spike during braking, and with a whole load of contactors, controlled by the HMI, to keep the voltage in limits. Even has 2 package air conditioners as well to keep it cool, and 200VAC fans to circulate the air inside. All parts are made in Japan as well, and all the assembly was exactly perfect, even to when placing the 6 ton cabinet, it was exactly, within 1mm, of the footprint of the old one.
