Ok. So i found some things out this morning. I bypassed the wire that was giving me a ground fault. No more ground fault. No that i have this wire plugged into my inverter i have power to my frig. From inverter and shore power. I have two wires that normally go to the inverter. I believe 1 wire goes to the breaker for the frig and tv’s. So its tied in at the inverter and not the breaker panel.

The way my coach is wired is...

Inverter Input @ Breaker Box

- Black (Hot) Wire to 15A Breaker
- White (Neutral) Wire to Neutral Busbar
- Ground to Ground Busbar

Inverter Input @ Inverter

- Black from Breaker Box to Hot Terminal in Inverter Input
- White from Breaker Box to Neutral Terminal in Inverter Input
- Ground from Breaker Box to Ground Terminal in Inverter Input

Inverter Output @ Inverter

- Black from Hot Terminal Inverter Output
- White from Neutral Terminal Inverter Output
- Ground from Ground Terminal Inverter Output

These run directly to the outlets for the TV's 7 Fridge based on your floorplan.....



My Modifications - Subpanel

- Black from Inverter Output to Hot Breaker Busbar in Subpanel
- White from Inverter to Neutral Busbar in Subpanel
- Ground from Inverter to Ground Busbar in Subpanel

Romex to Fridge and TV's

- Black (Hot) Wire from Subpanel 15A Breaker
- White (Neutral) Wire from Subpanel Neutral Busbar
- Ground from Subpanel Ground Busbar

These run to a junction box for two TV's, two fridges and a couple outlets in my coach.



I upgraded to a 3000W Xantrex Inverter / Charger and added two more 20A breakers in the subpanel from the Inverter output to back-feed the Power Distribution Box / Breaker Box so my Inverter can power the entire coach... including the A/C's. I have 850Ah of Lithium as well.

Thank you this is great information. I do plan on redoing some of electrical in this coach. Just running out of time to do it now.

So i ended up finding the root cause (i think). The electrical outlet the feeds the outside tv was causing the ground fault. I think this going bad or getting damp is what smoked my inverter.

Not sure it would have saved your Inverter in this case but Thor not adding a subpanel and breaker in the Inverter ouput is a bad practice. A problem kn the output side will likely smoke the inverter instead of tripping a breaker.

That’s why I added a subpanel as pat of wiring my coach to use the Inverter on any circuit.

You might be right, I remember my class did, but to tell the truth, never tried on this coach.
I might be wrong.

Hey Terry....

The Magnitude / Omni's only have the fridges, two TV's and a couple outlets wired to the Inverter output. I'm betting the earlier Super C's were similar.

When I installed the 3000W Inverter / Charger, I rewired the coach so it could power everything.... within reason.... from the Inverter. Haven't tried the Microwave / Convection yet but I have run one A/C off it.
