Big fan of techtop motors. No-load = ~18A 50% load = ~27A 75% load = ~38A Based on your 200A service, at best you could operate these motors to ~75% of their rated power (12HP). Assuming nothing else is online, and you've got the right wiring to each motor. Start up however is a big issue. You absolutely cannot start all at once. Not even if they are free-wheeling. You'll need to start one at a time. And you'll need a method to trip them if they exceed >~38A draw. VFDs can do all of this, however they are less efficient.. A programmable soft starter with bypass is better: cdn.automationdirect.com/sta… That's $5k in soft starters for the easy way. Or the hard & dangerous way: 1 soft start microPLC contactors current monitoring* Program it to start a motor, then bypass it and move to the next motor. But you can only do this once per hour based on soft start rating of 5-starts per hour. And the current monitoring can get complex, or just use fuses.

it's a connected microPLC so you can use it to control machinery, as a gateway etc you can even do TinyML on it :)
