Attached NEC 2017 exhibit the transformer is grounded and their is a supply side bonding jumper to the secondary panelboard.
However in the secondary panelboard their is also as the exhibit calls it supply side bonding jumper from secondary panelboard equipment grounding terminal to the panelboard enclosure
NEC 2017 section 250.30(A)(2) says supply side bonding jumper can be wire or bus type.
However in the secondary panelboard my supply side bonding jumper from secondary panelboard equipment grounding terminal bus to the enclosure is manufacturer provided screw.
Questions;
1. Can that part of from secondary panelboard equipment grounding terminal bus to the panelboard enclosure supply side bonding jumper or not?
2. Can that part of from secondary panelboard equipment grounding terminal bus to the panelboard enclosure be manufacturer provided screw or not?
