Sources and method
No operator flow feed is linked to this profile. The map and hardware describe the registered connection, not a current power transfer. A rating describes the equipment; an operator’s posted directional limit, when available, is a separate operating value. The map point identifies a sourced terminal or crossing where available, or a representative connection point; it does not trace the full route.
