As a general note, whist the current clamp is non-invaslive and does not connect to any live wires/cables, it must never be open-circuited once installed to a current-carrying conductor.

Part of the non-invasive connection to the live wire/cable, is the secondary circuit which is galvanically isolated from the primary circuit.
