Clamp on ammeters

Most clamp-on ammeters that electricians use work only on AC circuits. Clamp-on that work on DC are much more expensive.

The most direct method is to use a current shunt that consists of a high wattage resistor (low resistance value) placed in series with the motor. Voltage measured across the resistor is then used to calculate the current.
