[QUOTE="Phil Graham, post: 91077, member: 430"] Re: NEC 2013 Draft, OSHA, and Generators - Details and Discussion (long) Dick, Read the start of this thread for a discussion on the very details of when GFCI apply. If you view breakers for the purpose of over current protection, then not having neutral and ground bonded is sufficient to protect against excessive current, as a floating ground won't have any substantive current flow during the fault condition. The generator won't be over-tasked current-wise to ground, and no fire is started. Of course, the generator ground will quickly float to the line voltage because R in V=IR for the generator frame is essentially infinite. When considering an overall safety state, the floating ground raising the generator frame to the line voltage (or half the line voltage in the case of these differential output inverters) isn't so hot, of course.
