Wiring notesDolphin owner rule applied 25 October 2026: Owner rule: AC, DC two-wire and explicitly named two-wire models use two conductors. This rule takes precedence over contradictory historical source wire-count text. Conductor count is a catalogue configuration; terminal assignment and wiring-diagram verification remain separate.
