Oh my.I can't find what NEC Article this is either.
I don't see one, and there are 1p breakers!Grounded conductor may be the wrong color.
Can’t say as I’ve ever seen that done before! Kinda looks like it’s not here in the states, but……….I can't seem to find the appropriate Section in Art 312 for working space required in this particular installation
Perhaps the plumbing Code applies

Looks like Pex B.I can't zoom into the photo enough to quite tell whats going on. Is that actually copper tubing? I think it needs leak protection if it runs through a panel . Yellow & Orange and either black or brown?? Is that a 480V panel??
