+> [!cite] 250.122 Size of Equipment Grounding Conductors
+> **(A) General.** Copper, aluminum, or copper-clad aluminum
+> equipment grounding conductors of the wire type
+> shall not be smaller than shown in Table 250.122,
+> but in no case shall they be required to be larger
+> than the circuit conductors supplying the equipment...
+
+Apparently in the 2026 NEC First Draft Meetings,
+Code Making Panel 5 clarified that the equipment grounding conductor (EGC)
+never needs to be larger than the largest ungrounded conductor in any raceway
+when installed in parallel.
+I can not find a source to verify this.
