Does your ABB box output to the QC port of the Leaf? If not I don't see how you could charge at more than 6.6Kw using the Leaf J1772 port......
Also what is your 3-phase voltage? In my area it's either 120v/208v or 277v/480v. Unfortunately, the Leaf J1772 maxes out at about 260v so you can't even feed the 277v to the Leaf, it has to be either 120v, 208v or 240v. No homes here really have 3 phase power, almost all are 120v/240v and places like apartments are 120v/208v 3-phase.
