Breaker panels and gfci/afci breaker

[Peterjk]

Here's a higher rez pic of the panel.

and here's the schematic for the panel.
The left side is AC LOAD which goes to a 4 20a outlets.

The right side is a 10g plug into the Victron Pheonix 1000w a inverter.

The inverter ground lug is connected to the panels Neutral bus bar. This eliminated the "open ground" condition.

The Siemens Gfci/Afci 20a breaker is connected to the right most breaker pole, and then the white, and black wires from the Load. The GFCI wire, is connected to Neutral bar.
The Ac Load connects to the Ground bus bar, then to the Siemens Neutral and Hot connectors.

The Power supply from the inverter, connects to, the ground bus bar, the Neutral bar, and the Hot Breaker panel lug.

Inverters are not my specialty. I see how it has been fooled.

The groundIND wire is not the same as the neutral groundED conductor.
If the inverter lug is a green screw - from the factory, it ought to be grounding. Either in the panel, terminated with the ground bar or the at least the chassis. Chassis is on rubber tires, I'd prefer the panel, as the line side will be connect via the ground wire of the branch circuit. Thereby keeping the ground and neutral separate all the way back to the service main breaker.

Everything else in your diagram and within your panel looks great.

DeMac, could not have done this without you. I missed the PM part, this wasn't time sensitive. I have another year or two on this project.

Couple questions, as I still am a bit confused on minor things.

To energise the second breaker....should I ever need one. You mentioned earlier.
"You're service ought to be 10/3 (or 12/3) im hip to upsizing to 10.
Blk, red, wht, grn. One current carrying conductor, per breaker. The breaker termination is for only one wire, no joint."
Does that mean I can use the RED wire as the HOT for the second breaker?

Last bit about the Inverter "ground lug". Its NOT green, its silver. If I connect it to the Ground bar in the panel, I show an "open ground" with my tester. If I connect it to the Neutral bar, I show a good ground.
Checking a Victron site, we can see this schematic...
Mine is 12/1000 not 24/1000

Just wanted your thoughts on this. I don't want to take more of your time on this, you've been super helpful.

Short, Yes. Uses the same neut & gnd.
But it depends on your line side supply. If you only have a 30A 3wire back to the main panel, then you only have one hot. If you have a 4 wire, you will have 2 hots with 120v each, not always split phase, but ought to be.
You do have 30A load wire. Going back to a jumper or joint on the line side is up to you, I would advise against it.

Silver screws are usually neutral, if they use colored screws. Though, a neutral ought to be protected & travel accompanied with a ground.

Do check with the manufacturer.

RE: If you only have a 30A 3wire back to the main panel, then you only have one hot.

Well Im plugged into a inverter which is a 3 wire plug . So yeah. Answers that. Thank you!

Whats your thoughts on the Inverter ground vs Neutral?

REading this article, it seems to suggest, that at the source of power, which for me is the AC Inverter, not shore power...
"it is vitally important that the connection between the AC safety grounding wire and the neutral wire occur only at the power source. That means, at the onshore transformer supplying the dock shore cord, or at a generator or inverter—when and only when one of those is supplying power to the vessel."

Just saw you second comment, thank you: "Silver screws are usually neutral, if they use colored screws. Though, a neutral ought to be protected & travel accompanied with a ground."

I'll do a bit more research on this question, and check all contact points, with a volt meter.

Thanks again DeMac, and again, all your help is very much appreciated. I hope this topic helps another schoolie builder as well.
Cheers!
