Looking online I can't find anything that says the EU 6500 or 7000 has a master GFCI?  Maybe I am overlooking it.  Typically, I see GFCI's on 20  120 volt receptacles-standard OCP on the 30 and 50 A twistlock 120/240 v receptacle.  In a standby situation, GFCI is not necessary - the POCO 's power is not GFCI protected.

With a master GFCI that would obviously be a problem, but otherwise my thinking is that the only real issue is "objectional"  current in the EGC-which should not be detrimental if it is sized appropriately.  And that would be preferable to uninformed people running gennys without a bond.

in los angeles any generator thats built on a set of wheels has to be connected to a ground rod. even all of our contruction site gens had to have a permit from la building and safety and a ground rod driven at the gen. the electrical inspector would come and inspect before we were allowed to use it. a friend runs gens for tv/movie shoots , i will ask him what is required for his 18 wheeler gen rig.
i just talked to my friend about how he ground gens. he said an city inspector always shows up to make sure the gen is grounded. he said he drives a ground rod, finds a cold water pipe and get permission to connect to it, finds a service and gets permission to connect to it, etc. he told me he has seen burned up gens where the neutral was lost and the guy operating the gen didnt ground it. he doesnt know if an inspector had ben to the site or not. he told me he has heard about guys using rubber mats aroumd gens but he doesnt do that because even though it protects you the gen still isnt grounded. heres a foto of him and one of the gens he ran.

Of course that's the serious answer... wasn't nearly as much fun, though!  :P
