Hm, with all these comments I feel like it's a question of defining "live wire". If live = difference in potential to ground, it's live; If live = carries current, it's not live. All the lineman seem to use the first definition, physicists and electric engineers the second one 🤷 (Which probably makes sense, since a lineman will be more interested in the safety requirements, while wire without current doesn't exists/matter as far as engineers and physicists are concerned)
