Page is hugged to death right now but I strongly disagree with parent. I'm an EE and I'm quite familiar with the National Electric Code. I build high current/voltage devices and I've wired two houses (both of which passed inspection).

If you're trained, experienced, and generally know what you're doing there's nothing wrong with working on high power electronics.

The whole point of this post is that he isn't trained on that stuff.

To be honest, I think the guy learned more than most electrical contractors actually know or care to check when it comes to the EVSE. I certainly would object if he is selling this or installing on other people's houses, but this looks actually acceptable for now. The longevity is a big question, since usually there's no easy way to check / test that with a singleton bespoke design/build, and that's sometimes what distinguishes the one-off vs mass manufactured stuff, albeit in both directions. Sometimes a bespoke design misses some subtle design choice and it breaks down sooner, but sometimes you can do a lot more careful handcrafting and "simple" over-engineering with a bespoke singleton to make things last even longer than mass produced stuff. I think the mechanical and the environmental aspects - condensation, thermal expansion, etc - are probably the biggest question mark here.

Suppose you aren't trained, experienced or generally know about working with high voltage systems, like the author?

Then you learn you some, like the author.

Same way I learned to drive actually, behind the wheel of an 18 wheeler going down the freeway in the snow.
