Equipment containing a removable main bonding jumper that is not factory connected between the grounded service conductor and enclosure shall be marked as specified in 142.1 or 14,2.2.
9.3 Equipment intended for service equipment use may be provided with a high-impedance grounded neutral system if provided for in the requirements for the end product.
9.4 Equipment intended for use as service equipment shall have provision for connection of a grounding electrode conductor sized in accordance with Table 9.1 as specified in 4 and 4.5 — 4L8.
9.5 With respect to 4.4(c), the equipment shall have a terminal for a grounded service conductor even though there is no provision fr a load conductor to be connected to the grounded service conductor. If there is no provision for such a load conductor, the grounded service conductor terminal shall
a) Accommodate a conductor of the same size as the main bonding jumper shown in Table 9.1,
b) Be bonded to the enclosure, and
c) Be directly connected to the grounding electrode conductor terminal.
