Once we had an outlet installed the unit worked as planned and is now charging vehicles as expected. The only complication we had was that it shipped with a four wire plug that was incompatible with the other uses for our outlet. I took the chance and we cut the plug off, found that only three wires were connected, as expected, and replaced it with a three wire 240 volt plug compatible with the outlet. That's working well, and maybe useful for many US customers to know that even though it comes with a four wire plug, only the 240 volt pins and the ground are actually connected. Is there for possible to connect it to a 240 volt outlet without the common lead.
