I need a quick clarification on using a Ground-Neutral Bonded (GNB) plug on a Yamaha 3000ISEB (or any inverter type really). Not sure I am understanding something.When making the GNB plug, does the wire from the trailer have to pass through this GNB plug and into the generator for it to work?Reading elsewhere on the net, I get the feeling that if I make a GNB for one of the 20 amp receptacles, plug it in, then all my other receptacles (20 amp and 30 amp respectively), will also be bonded. True?

The GNB plug is terminated at the generator end since the generator is effectively acting as the energy source service panel.This single ended GNB cable can only be used for the portable generator and NOT as an extension cord when connecting to shore power.

What I did was got a spare male connector. Jumpered the ground to the neutral pins. I then plug it into a 15/20 amp receptacle on the genset. (Honda)

It is not necessary; don't worry about it.

Curious why you want to do this on a RV? The only reason I know of is some newer residential furnaces wont turn on unless the see the N-G bond.

Try this again.I should have mentioned, I was doing this to get my PI EMS-HW50C to work with my generator. Now I have to push the bypass.PI said to make the GNB plug, but they didn't say whether it needs to be on the generator end of the wire running from the generator to the trailer. Or does it need to just be plugged into an available receptacle on the generator, making all the other receptacles also bonded.Can anyone clarify this?

You can make it at either end. It will be electrically the same.
