Measurement Category:
To ensure safe operation of measuring instruments, IEC 61010 establishes safety
standards for various electrical environments, categorized as O to CAT.IV, and called
measurement categories. Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a measuring instrument designed
for CAT.III environments can endure greater momentary energy than one designed
for CAT.II.
O
: Circuits which are not directly connected to the mains power supply.
CAT.II : Electrical circuits of equipment connected to an AC electrical outlet by a
power cord.
CAT.III : Primary electrical circuits of the equipment connected directly to the
distribution panel, and feeders from the distribution panel to outlets.
CAT.IV : The circuit from the service drop to the service entrance, and to the power
meter and primary over-current protection device (distribution panel).
