Ting monitors the entire electrical system of your home, not just the outlet the sensor is plugged into - or the circuit it is on. Once plugged in and installed, Ting detects hazardous arcing on all home circuits regardless of voltage - 120V or 240V.
Note: The majority of homes have a single main electrical panel - one Ting is sufficient in these situations, even if a subpanel is also present in the same physical structure (in other words, the subpanel is not in a barn, shed or detached garage).
However, for homes that have more than one main electric breaker panel (i.e., has its own separate feed from the electric meter or utility) one Ting is required for each main electric breaker panel. As well, if a sub-panel is installed in a detached or remote building a separate Ting will be required for that building (i.e. barn, shed, detached garage).
