Does anyone have some knowledge about old wiring practice?
My unit has a 30 Amp electrical panel with the light on top that is attached to the neutral bus bar and then is grounded to the skin of the trailer.
Also the service ground is bonded to the skin.
I understand that current practice is to not have a grounded neutral.
The wiring is all #12 w/ #18 or 20 ground attached at light fixtures and connected to the skin at j-boxes and receptacles.
I energized the system from my generator ( the GFI receptacle from my shop would not allow) and everything seems to work but am uncertain about the system and the function of the light on the panel and how it works.
Is it a warning light of a hot/neutral mail function?
I have seen other references to this on other threads but without pictures.
So I am posting some photos for reference.
I have also changed out the two prong receptacles for three prong grounded ones with the ground attached to the skin.
P.S. Here is a link to an interesting article on RV/GFI.
