Confused about wiring my Recent Purchase
Good evening guys and I hope you all can help me. I have gleaned a wealth of knowledge so far but have come here for the advice from people that know RV's. Story .... Moving into an RV for 4 mo...
Forum Discussion
Well sigh* The more I read the more confusing it gets .. however I will not be deterred and I am gaining more knowledge by the second.
Looks good with my shopping today though - I can go ahead with my purchases, will just need to validated neutral/ground bonding or not.
I appreciate all the advice as always.
This is an interesting forum post I read where this guys seems to have had much the same situation I have with old wiring.

What is interesting here is that I see grounding rods simply provide lightning strike paths and grounding for high voltage spikes and NOT really a valid path for Fault electricity.
Apparently also, I did not factor in, if the barn had a metal conduit / path of some sorts. My barn does NOT have gas or water inside but does have a Permafrost water tap Outside ... fortunately I know that it is supplied from the house not by Metal Pipe but by plastic PVC, so I should imagine that won't be counted as a valid return source.
So in effect the wiring in the old sub panel of the neutrals and grounds together was not altogether bad for the code at the time, they just seemed to be missing the grounding rods. Also the bad thing about the installation in the old box was the Neutral Buss was floating so in effect the panel was not grounded.
So back @KD4UPL and DUSTY R, I think this is where you guys were coming from. With new installations and new wire runs to a detached building WITHOUT supplied gas water returns then a 4 wire installation would be used (2 Hots / Neutral / Ground). There would, even in this situation be grounding rods used for potential lightning strikes.
So here's my question ... in effect Bonding the Neutral and Ground Buss Bars in the new panel (or attaching the Ground Rod Wire to the neutral bar) is the correct thing to do ? Alot of the confusion seems to come from whether or not it is OLD installation and 3 .v. required 4 wire feed by todays standards and code.
Interesting Discussion also HERE !
Again many thanks for this discussion, there seems to be a large variety of differences in advice from site to site. This discussion is definitely increasing my knowledge and understanding.
