I would not use it if it was free.
If I were you, I'd avoid reading any topics that begin with "Do It Yourself". I like to request that you at least avoid the silly comments. It's very obvious to everyone that it's a DIY project. I have already stressed that nobody attempt this unless they are qualified to work on high-voltage electrical projects.
It's questionable whether any kind of device like this could meet NEC. Can it be safe? Definitely.
Keep in mind the NEC (National Electrical Code) is written by the NFPA (National Fire Protection Association), which is largely made up and financed by fire insurance companies. Their motivations can sometimes be, shall we say, "excessive" compared to reasonable engineering standards. Thusly, the code is extremely harsh on 240v in this country, which is why we have so much trouble charging our EV's. People have been using 240v all over the world for almost a century, and WE are being injured more often than they are!
I call this the "Danger: This sign has sharp edges" phenomenon. We are so concerned with liability that we try hard to protect people from everything, including their own stupidity. The big problem is this kind of thinking actually breeds stupidity! When I was a kid, the playground was a rough place. There were about a thousand ways to seriously hurt yourself. You quickly learned to hone that self-preservation instinct and not kill yourself in a freak monkey-bar accident. Has anyone seen a playground lately? They are all neoprene-coated, safety-padded, non-toxic, yellow stickered, no unattended childen allowed places! We are slowly removing the impetus for people to think for themselves and learn from their mistakes. If you don't make mistakes, you can't learn from them, it's that simple. We are closing parks because they have "dangerous" places, like cliffs without safety railings and on-duty safety officers. It's insanity! So excuse me if I react unkindly to FUD.
If you are bored, go on over to the Chevy Volt forum and start a big ruckus there, the L1 EVSE that they ship with the car is NOT UL listed if you can believe it! They use 16awg wire throughout, and the unit is not even sealed from water ingress. One good drop on the pavment and it will crack wide open also. I doubt it would even pass UL's tests.
