Hello, I have a murray panel here. Has a siemens logo below so I’m assuming post 2002.
It looks to me like the neutrals are not bonded to the grounding bus bar and GEC. This is a main panel it’s directly opposite the meter and only 1 other 2 breaker panel exists in the 1300 square foot home.
Can you find a bonding screw? I’m not seeing one that I can tell.
Should be at this location if the bonding strap is installed, but that fat neutral is blocking the hole on the busbar for the strap to be inserted into. At 0:16-0.17 sec in the video you can see the hole in the panel body for the bonding screw.
I agree, bonding screw (MBJ) is missing and if that larger solid conductor is the GEC it must terminate on the neutral bar unless the MBJ is a wire or busbar.
If you look at the schematic drawing, it looks like the ground and neutral are connected? Also, The tag shows and explains how to bond the neutral bar.
