Pic of my 200A service panel. 24 space. Looks crowded but will be significantly freed up very soon. Converted to natural gas range, water heater, and dryer. This has freed up many spaces. All that aside I want to clean up the box. Want to know if it is safe/legal to install a neutral/ground bar on the LEFT side of the panel and then have all the neural wires on one side and ground wires on the opposite side as I see in more modern boxes.
