Sine Wave Inverter Anomaly
After following this recent discussion about how to best utilize a sine wave inverter for RV use I decided to go ahead and buy the 1000 watt model mentioned in this discussion since it was on sale for...

There is little advantage to bonding a portable generator if there is no low impedance earth ground (i.e. an 8' 5/8" driven ground rod ...
Which obviously none of us are going to do in a campground. However, bonding neutral to ground, as indicated by my measurements, does eliminate strange voltage readings where one wouldn't expect them so the question is whether there is still value in bonding to prevent these voltages from possibly causing any problems with the equipment being fed. :@
The main reason for bonding the output of most inverter generators is so that your EMS will allow the trailer to connect.
Which seems to not be a problem with my Surge Guard as it does allow the trailer to connect regardless of whether I bond the source or not.
As to definitive answers, some generators have a switch to bond/unbond the ground/neutral because even OSHA inspectors are confused by the grounding & bonding requirements.
Good grief, if they don't know how are we supposed to know?! :S
