Hi,
My customer wants to use 2 VFD (not installed in the unit) powered by two differents power connection. Each VFD will supply 3 motors. I will provide the motor protection inside the main control panel for each motor.
The question:
Am I obligated to provide two disconnects inside the control panel or it could be only 2 splitter block.
The article 409.110 ask me to identify each incoming supply circuit, but I don't find something about the disconnects.
Thanks
