Tap conductors for multiple motors with a single breaker feed

[Akten]

Hi,

I am working on a project where the HVAC unit has more than one motor (lets assume 2 motors for now) and those need to be operated by a single VFD (VFD is going to be located outside of the HVAC enclosure). I am trying to figure out the electrical connection and I am not 100% sure about how to meet the code in terms of splitting the single VFD connection to 2 motors, I am thinking this would fall under requirement of tap conductors? My understanding is that tap conductors have to terminate on an OCPD to meet NEC.

I am attaching a sketch here to see opinion on if this would meet code requirement.

Basically, a single feed is going to VFD which then goes to HVAC disconnect, and there will be a terminal block in the HVAC unit which splits the connection to the 2 motors inside the unit. If the conductor inside the HVAC are considered tap conductors (highlighted in yellow), then does that mean an OCPD have to be on the upstream of each motor (within the HVAC)?

Thanks.

There’s a lot to consider here, but to just address your specific question, as long as the conductors are protected at their ampacity, they are not taps.

Next move the VFD to load side of disconnect.
And as retired said, you have a lot to consider.
RTFM of the VFD you have chosen before going further.
