Disclaimer again - not an electrician but this is how I understand things based on my DIY edumacation. Please correct me if I am completely off base here!! Yes, but I interpret that original neutral as a completely different neutral than the one being discussed. That neutral I assume is the...

uhh boy...makes complete sense(??!!) That's another reason (aside from burning my house down) that I didn't want to replace the harness with my own. Thank you for your help - really do appreciate it!

Oh yeah…:oops:I was thinking his transfer switch was “standalone” & not connected to a main panel, which was a really dumb thing to think!!

First post -I have been reading for about two months & have learned a ton. Thanks to all the knowledgeable individuals on here! Please excuse in advance any display of ignorance and/or mistakes in my diagram - Please point out & correct either!! I have an EG4 6000 XP along with a 14.3 kWh EG4...

Would also need N-G bond "on" in inverter, yes??

So I guess that explains why they don’t sell a longer harness! I’m getting the impression that my Pro trans transfer switch is a bit on the “shady” side with regard to sizing. That presents me with a problem because I need to “extend” my wiring harness between the Xfer SW & my main panel. The...

Are you saying the neutral is unnecessary in general (except for GFCI) OR in the specific cases listed here by me & OP where there is another (separate) neutral between the inverter & the Main Panel. You need a neutral between the back up source (GEN or Inverter) & main panel somewhere, no...
