What type of device allows you to measure current without disconnecting wiring?

The clamp-on ammeter is specifically designed to measure electric current flowing through a conductor without needing to disconnect any wires. This device features a hinged jaw that opens to clamp around the wire, allowing it to sense the magnetic field generated by the current flowing through the conductor. This makes it incredibly convenient for technicians and electricians, as it enables them to take accurate current measurements quickly and safely without disrupting the circuit being monitored.

In contrast, devices like a multimeter typically require the circuit to be broken to measure current directly by placing the meter in series with the load. Voltage meters and power meters serve different purposes, focusing either on measuring voltage in a circuit or assessing the total power consumption, respectively. Hence, the clamp-on ammeter stands out as the ideal tool for current measurement in live circuits without interruption.
