Bonding bushings on SERs for sub panels?

[Danielinho]

Good morning. I’m working on an apartment complex that has about 200 units. The electrical inspector failed us because we didn’t have a bonding bushing on the electrical panels( sub panels). We have SERs with Romex connectors. I thought we were in compliance. SERs are not raceways, what did I miss? He made us install bonding bushings to all sub panels.
Thanks in advance

You didn't miss anything. Your inspector needs to read the code. 300.4(G)
Good luck

They're not required. If the voltage is below 250 volts to ground they wouldn't be required even if you had a metallic raceway and concentric or eccentric KO's. In fact no bushing is required with an SE cable connector. And what exactly does the inspector think that the bonding bushing is actually bonding?

Yeah I am wondering if I am missing something here. Like just to bond the cable connector?

I hope you didnt do it yet? 200 of them?

Not yet, we are going “fight” it

Good idea, the inspector is clearly wrong on this one.

Great! Print this thread and show the inspector. Better yet, invite them to join this site.
I thought I was smart until I found MikeHolt.com

Does he want a bonding bushing or an insulating rounded bushing for conductors 4 AWG or larger?

A bonding bushing

A bonding bushing

Did he say why and cite a code section that requires it?

That's nuts. Aren't the enclosures bonded to the EGCs?

There is a law in Pennsylvania that compells Inspectors to name the specific code section you violated. I imagine other states have this regulation. Exercise your right and ask them to do what they should have done in the first place. Like Mike Holt says, I don't talk code with anyone unless we both have a code book in front of us (or at least tell me what section they are referring to.)

Since there is no violation it might take a while for this inspector to realize that they cannot find it in the codebook.
