This panel is made up as a sub panel. Is there a disconnect at the meter?

If there is a service disconnect ahead of this panel, as Greg suggests, then the neutrals & equipment grounds must be kept separate. If that is in fact the case, then the metal bar at the bottom of the second picture must be removed in order to keep the neutrals & equipment grounds separated.


In addition, the ground screw & bonding strap will need to be installed to connected the equipment ground bus ( on the left side of the panel) to the sheet metal enclosure.

Connecting two neutrals in one terminal is a violation of the NEC & those connections should also be addressed.

If there is no service disconnect ahead of this panel, then the bonding jumper must be installed and the bare equipment ground in the cable feeding this panel would need to be disconnected.

Hopefully, any electrician that evaluates this panel will understand the code isssues involved, the original installer didn't.

Thank you for the replies. Yes, there is a panel with a main disconnect ahead of this panel. From what you tell me, they need to remove the bottom bar to separate the grounds and neutrals. Then, they need to install the grounding screw and bonding strap. Finally, seperate those doubled-up neutrals.


I appreciate it!

Yup Hank and you are right about the bottom bus crossover I missed that.


The bond will go on the grounding side.
