Again, I’m a real beginner. I just spent another 4 hours over two days reading info on this forum, and now I am even more confused. Yes, I read "Mobile Grounding Made Simpler . . . and several other threads about RV/mobile inverter grounding, one with a lot of technical debate was waaaaay over my head. I could not find a clear-to-me solution for my issue.
I just bought a new 3000-watt inverter. As careful as I was in attempting to double-check all details before my purchase, I missed one (important?) thing. It is that there are only 2 connectors -- the pos (+) and the neg (-) for the permanent 120 volt AC output wire that goes to my 120V RV breaker panel. There is no ground connection for the permanent wiring to the AC breaker panel? Note: Yes, there is a small ground connection for the aluminum case of the inverter. But, that's completely different, as I understand it.
What do I do with the ground wire on the 3-wire connection from the inverter to the AC breaker panel? I contacted the Amazon seller several days ago and, so far, no response. I watched several YouTube reviews of the inverter before I bought it, which were very positive about the inverter’s performance.
One of the reviewers was kind enough to respond to my question about 120V AC output grounding, saying "In the RV, just connect the (+) and (-) inputs. You can ground the metal housing of the inverter if you'd like." But, as I understand it, chassis grounding the metal housing of the inverter is not properly grounding the 120V AC output to my RV breaker panel and system. That leaves what seems to me to be a critical path grounding connection wire from the inverter to my breaker/120V system panel ungrounded? And, that is VERY scary to me.
Does, or does not, the permanent inverter connection to the 120V RV electrical breaker panel need to be grounded?
If no ground connection is necessary, is this a 100% safe way to wire the permanent 120V connection from the inverter to the breaker panel?
Thanks in advance to all of you who provide such valuable info for beginners. You are amazing.
