My understanding is that the AC ground to earth is connected to the case of the convertor via the plug. So it seems that there would be no need for an additional ground to earth via the frame.
Why is the DC negative wire also wired to the frame which is also part of the negative circuit of the 12V system?
Maybe it is important to connect the negative component of the DC system to the earth ground of the AC system?
Thanks for helping me understand this.
As stated previously in this thread, NEC Art. 551.20(C) requires the enclosure of a converter to be connected to the vehicle frame with a minimum #8 copper conductor. Period, end of issue.
Yes, I read the thread. I am wondering why this is required. Of course, I would follow requirements of code, but I wanted to understand why.
Thanks for all the answers. I still don't understand why two grounds are necessary in the AC side and two paths to negative side of battery are required in the DC side.
