Main panel
I am adding a few circuits to a panel and confused about the configuration of this panel. It has four separate bus bars at the bottom of the panel. Currently the neutrals and grounds are terminated to the same bus bars. Is this correct? In the past panels that I have worked on, they had separate bus bars for the ground and neutral. Thanks for the help.

Its ok if it is your main panel. Sub panels require a seperate ground bar.
An easy way to tell is by the number of conductors in your service entrance cable. With a 3 wire system your neutrals and grounds will all terminate on the neutral bar (usually 2 of them, 1 on each side of busbar). With a 4 wire system your grounds and neutrals are terminated on seperate bars.
