Grounding and bonding: Service entrance, separately derived systems and transformer grounding

Part 3: Grounding and bonding: Service entrance, separately derived systems and transformer grounding Two professional engineers (Dan Carnovale and Tom Domitrovich) with years of power systems experience will clarify this often misunderstood concept while making reference to NEC.

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

[@bennyfreeman7705]

Very informative video. Easily presented and explained. Thank you.

I love this guy's passion. Sincerely.

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 ?

[@Diesel437]

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

Nice
