strung together this:

Not any expert on 3 ph setups, but I was under the impression that you
designed cable sizes for the working load and not the startup current
since it is only a short duration transient?

Quite right, any motor and most inductive loads will take a large
surge at startup. The continuous circuit current is the one that
determines the cable size. You would also provide motor rated MCB's or
fuses to cope with the startup current.
