The best video i’ve ever seen explaining grounding/bonding

At 1:29, wouldn't that be a system bonding jumper and not a main bonding jumper?

[@safetythirdified]

In the graphic ex. @1:32. Are we not interchanging the term Main Bonding Jumper for System Bonding Jumper? Isn't that a SBJ at the X-former and MBJs are located in first disconnecting means enclosures?

[@bobcocampo]

Will there be an objectionable current if you bond the neutral from the utility to ground in the service equipment

[@j.s3612]

What do you mean ?

[@PortlandFleetService]

No, @1:21 he shows the ground from service ground in the transformer

[@j.s3612]

No there shouldn’t be because the utility neutral is bonded and grounded before it reaches main panel and after
