Question on QO-20M Square D panel


I was wondering if there are any limitations on where I can place double pole breakers in this QO-20M panel? (other that the fact that they need to be on seperate phases).

Question on QO-20M Square D panel


Thanks.
I was also wondering if I should add a ground bar to this panel? I am putting in a sub panel to get rid of a bunch of the tandems that are in now and I notice that all the ground wires go to screw connections in the case itself? (and there are only 4 of them)

Add the ground bar kit. You will need it later.

Question on QO-20M Square D panel


Are the ground bar kits specific to each panel, or just to the manufacturer?

A ground bar is a ground bar but the mounting holes/screws are panel specific.

Technically you can't use self tapping screws....unless they are self tapping machine screws.

Self tap it if necessary and don't lose any sleep over it.
