The notes on the image indicate that the style SER has both a neutral and a ground, but the image only shows a bare neutral. Besides, why would it have a ground if it is being used as a 3 phase service entrance(SE)? If it was being used as a feeder on a split phase subpanel, the bare wire would be the ground and one of the “hot conductors” would be a neutral.
The neutral in the SER is incorrectly identified in the graphic above. The bare is the grounding conductor.
You can see how complex it is to label a graphic like this when there are so many variables. The SEU graphic is fairly accurate but there is no “inner jacket” on the individual ungrounded conductors. The proper name for that is conductor insulation.
For the SER what is shown is correct only when the cable is being used as 3 phase, 4-wire service entrance conductors. For other installations like a 120/240 volt feeder to a panel one insulated conductor is the neutral and the bare conductor is the EGC.

SER conductor description still wrong.
Not enough info for graphics artists. Can you be more specific for them?
Wait, I see the issue. Thanks.
Not fixed yet. The neutral is not bare in SER.
SE has 3 conductors, not 2 and a neutral. The neutral is a conductor. Depending on the usage the bare can be a neutral or a ground. Still needs work.
??? The image doesn’t show a bare neutral.
The description does.
Ah. Thanks!
