make it twist lock to 30amp RV female or buy it online
thats 3 wires, 1 hot 1 ground, 1 neutral
you use (2) adapters, 50amp female to 30amp male (this adapter is already wired correctly), then plug that into the NEW 30amp RV female to twist lock adapter
That's what I've decided to do. We got through the weekend by using our neighbor's external portable genset and running a drop cord to a fan. The nighttime weather was very pleasant! During the day, I ran the on-board genset with the Genturi, and whereas the CO alarm never activated with the Genturi connected, I brought the CO meter from my office and measured some pretty disturbing levels of CO inside the rig with the on-board genset running. Our "level of concern" when we go out to houses with alarming CO detectors is 12ppm. That's well below the immediate danger to life level is, but enough to know that there's a problem. CO detectors don't start alarming until the level reaches 70ppm, and by the time we arrive with a calibrated meter, the household has usually already vented the residence. We try to duplicate the situation by turning on gas-fired heat or other sources of CO. At 12ppm, we usually recommend that the household turn off/extinguish all sources of combustion until the CO source can be isolated and resolved.
With all that said, the meter readings I got while my on-board genset was running WITH the Genturi attached and properly working, (judging by the toilet paper suction at the venturi opening), were anywhere from 9ppm to 19ppm, depending on where I took the reading. The highest was at the closed kitchen sink window, directly above where the genset is mounted in the basement. Now, mind you, the 9ppm is almost background standard for outside, BUT, when it was creeping up to 19ppm, I was concerned. I let the genset continue to run for several hours and never got higher than 19ppm inside the rig. But that's too high for me to be comfortable trying to sleep with it running.
Sooo....I figure there may be a slight leak in exhaust manifold, a crack in the pipe somewhere or there is simply an inherent risk in running the genset that I'm just not willing to take when I'm asleep. I don't mind running it going down the road, or to cool off the rig in the daytime, but it gets shut down and ventilated before bedtime.
