For those of you that have used VFD cable...
I've got a 373 MCM shielded VFD cable. The egc is symmetric - (3) 6 awg conductors.
These will terminate to a ring terminal --> 3/8" stud.
Do I put them all under 1 ring terminal of an equivalent cross sectional area (6 awg ~ 26.2 MCM 8 * 3 ~78.7 MCM which is between a 1 and 2 awg) or do I put them under 3 separate ring terminals?
I'll have 3 of these cables in parallel so individual would be a total of 9 terminals landing to my termination point (3/8" stud). It's going to look like a christmas tree ornament with all that hardware stacked on it.
Any thoughts or advice?

I haven't, but that doesn't always stop me.

Are you talking about joining one conductor per cable, or all conductors in each cable?

I imagine the terminals are rated for single wires, would make better connections, and be more flexible.

There are terminals shaped for stacking. Another option might be be a 3-hole lug.

Joining the (3) grounds from 1 cable into 1 connector

I've not yet looked into ratings and I imagine you are correct. It may be futile anyway looking for a compression terminal rated for more than 1 conductor.
Connection I think is negligible using a 12 ton press.
I would be willing to sacrifice some flexibility to decrease connector count by 2/3. With a single connector I will have to expand the grounding bus - which means going to the drive mfg and getting some blessing that the warranty won't void, etc.
