      Yep, neutral is blue, ground is green/yellow striped. The latter everywhere, e.g. in a server cabinet you’ll mostly find the strap between body and door in yellow/green.

      Phases, L1 to 3 are brown, black, grey. Or you may use numbered cables for rail interconnects if necessary. You can see me getting a bit sloppy with all brown 16mm² for L1 to 3 leaving the meter slots, but they are numbered then.

      Every outlet gets ground, neutral and one phase, so usually I’d enter a room with 5x1.5 NYM and then connect the phases alternatingly to the outlets while forming a chain throughout the room, so phases get loaded equally in daily use.

          So only defined isolation distances between phase and ground exist which would not be the case when an unisolated ground wire could just slip into phase distribution rail or into a phase connection.

          EDIT: Also, the distribution panel even with the front off is defined as touch safe for something the diameter of a finger. An uninsulated ground wire that suffers an error would break that definition.

            Fair, and that makes sense. But it’s the US, so…we suck 🤷‍♂️.

            (I just imitated what the electrician did when he installed the load center.)

              Wouldn’t say that, you just put the weight between “git er done” and safety/predictability somewhere else. Has downsides, has upsides.
