    Phone dudes hook up a line to a device which sends a frequency thru th
    eline so you can find where it physically leads to. How can I buy a low cost (low use) version of such a gadget? One that also works at higher (eg 120VAC) voltages?

    I appreciate the signal will be lost at transformers (why we were unable to use power lines to transmit submetering data and why the power and rails
    firms failed in their internet biz plans).

    Look for telephone testers > Toner and Banana. In 47 years never
    tried them with 120vac. Electricians use something to trace cables.

    The telco item I recall was 'fox and hound', some variant still available

    <https://www.triplett.com/products/3388-fox-hound-hotwire-live-wire-tracer-tone-probe-kit>

    but the familiar 120VAC items use a different technology (not a 'signal generator', just a diac used as
    a near-zero-crossing pulser). They're cheap enough
