I ran into this yesterday and I wanted to make sure I was reporting it accurately before I push out the report to the client. The power is coming in through the box on the right that has a main disconnect lever. When I pulled the panel cover on the left panel I found this. It looks like a bonding screw is in place and the neutral is not floating. I believe this is now considered a sub panel because the main disconnect is in the tan box on the right. So my question is, should the neutral be floating in this sub panel on the left? Thanks for any input all.
Did the disconnect switch on the right have fuses in it? If it did then you’re correct about the panel. Any photo’s of the inside of the switch and the wireway underneath with the cover removed?

I only see a 3 wire feed to the panel. What was the nipple between the trough and the panel made of?
Looks like it’s too short the be PVC.
Robert,
I could not get that tan panel open. I tried several times but stopped when I felt I had reached the point of possibly damaging something by applying more force. Never tried to open the trough. What would I be looking for in there? It’s a local job so I could try asking the agent to revisit the property tomorrow to see if I could investigate further.
Jim,
The nipple was plastic. I’m assuming your asking because if it’s plastic that would negate the bonding screw?
Thanks for the quick response fellas. Guys like you are lifesavers when i run into weird scenarios.
It seems strange that there is a 200 amp disconnect for a 100 amp panel. You couldn’t open the disco because the switch was in the closed (on) position. There is usually a latch release on the side. I’m curious what’s in the wireway because it seems like it’s not needed to feed one panel.
Makes sense. There were actually three other sub panels on the property. One was in the basement and one was in the master bedroom. The last one was in an out building.
Need to follow the power coming into the complex. Before reporting anything.
Could be multiple power feeds comin in.
I’m guessing that the service entrance conductors actually enter the wireway and are then tapped to the disconnect and to the panel. It would be strange for the SEC’s to enter in that 2" raceway to the far right of the disconnect. Only way to know for sure is to remove the wireway cover.
Sounds like I need to orchestrate another trip to the property and check it out a little better. I’ll let you guys know how I make out. I really appreciate all the help.
That may help to properly answer your original question about the bonding screw.
