Installing @ my work
We have 3 phase, does that change anything?

I would contact the EVSE vendor and ask them before trying to hook up the unit to 2 legs of a 3-phase circuit. It doesn't seem like a good idea to meBetter yet, get an electrician to weigh in on the subject.

Just make sure the 3 phase is 120v/208v and not 277v/480vBasically no N. American EVSEs operate off 277v, max voltage is something like 260v.
Like at home to use the maximum charging rate(with a 6.6kwh Leaf charger) you'll need a minimum 40a breaker with minimum 8 gauge wire, 50a breaker and 6 gauge being best.

The other is whether the loads would become unbalanced to the point where this would cause issues for any 3 phase equipment in use (eg a precision or high power motor). It's possible none of this is an issue for this installation but I would contact an electrician unless I was certain.
