This is a outlet I pulled out of a 28KW winco PTO generator It had no neutral wire just this jumper connecting the neutral to the ground. Seems to me once the plate screw on that outlet got loose it would get a little sparky...........
GFI? Doesn't that require a ground reference? All small portable generators here are floating systems without a grounded pole, so all they can do is use protection like in an IT (isolated ground) system.
No, Texas, a GFCI does not need a 'ground reference.' All a GFCI does is measure current going out through the hot wire, and compare it to current coming back in through the neutral wire; if they don't match, it trips.
If the generator isn't grounded somewhere the GFCI will not trip because there is no return path to unbalance the circuit. I know we always say you don't need a ground to trip a GFCI but that is because the utility is a grounded supply.
Are not neutral and ground normally strapped together at the distribution panel?
Since the genset is the power source, distribution panel and outlets all in one, wouldn't it make sense to strap them together there?
Or should they be strapped together before the run to the outlet?
Since the frame of the generator MIGHT be grounded, I would want a nice solid return path in the event that hot shorts to a metal chassis in a tool that I'm using. Better to trip the breaker than have 120V AC finding a convoluted path through my body, into the ground and back to the genset...
I have a Honda EU2000. Neutral is NOT connected to ground. Case is plastic. Although you could have an internal fault that would cause a ground fault (on ether leg)I like using this unit to power tools and such used in wet or damp locations due to its isolation. I have to admit, this unit is one of the best purchases I have made. Quiet, only 49LB, 12-14 hrs on a tank of gas,very stable voltage and 60 cycle ( 1.1 gal)Beats a 200 ft extension cord.
