Note 3:
Measurement Category I is for measurements performed on circuits not directly connected to the
electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical
supply system that powers equipment. This category is for measurements of voltages from specially
protected secondary circuits. Such voltage measurements include signal levels, special equipment,
limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.
