I'm in the process of creating an electrical control center for our '79 Excella 500 renovation and have a question about grounding the AC and DC electrical systems.
Let me start off by saying that all the DC loads in my AS are grounded to the frame (lights, etc...), which means I need the DC negative to attach to the frame as well.
I have the
WFCO 8930 AC/DC distribution panel and I guess at a high level my question is if I can use a single copper grounding cable (connected to the chassis) to ground both the DC Negative and AC Ground Bus Bars by putting a jumper between them (see the
Cyan/Teal outline in the image below; I added this jumper, it wasn't like this from the manufacturer). Is this a bad idea for any reason?
The alternative would be to run 2 separate grounding cables to the frame for each system (one for the AC Ground Bus Bar and one for the DC Negative Bus Bar) but I don't see the point in that since they both get connected to the frame.

Here's a diagram of the distribution panel too if my image wasn't clear:

Any guidance would be appreciated, thank you!!!
