No, this cable locator cannot be used on 220V cables, even when de‑energized.
It is designed only for non‑energized cables or low‑voltage cables ≤24V DC/AC (digital mode only).
It does not support 110V/220V/230V high‑voltage cables, whether live or dead.
Also, it is not for shielded cables or cables in metal conduit, but it works for direct‑bury non‑shielded cables only if ≤24V and de‑energized.
