fuling 5.5kw vfd and 4.5kw er32 3 phase spindle

[adscnc]

Hello

I'm upgrading my 2.2kw spindle and VFD to Fuling 5.5kw vfd and 4.5kw er32 3 phase spindle.
I am debating the cable size from VFD to spindle.
The spindle motor plate states 3 phase 380v 9amp. Its 3 phase into the VFD and 3 phase out to spindle.

So would 16awg (1.5mm2) 4 core shielded be suitable- what would you use?

If so,can any one recommend a supplier for 8m?

thanks
Al
