To ensure safe operation of measurement devices, IEC 61010 establishes safety
standards for various electrical environments, categorized as CAT I to CAT IV, and
called measurement categories. These are defined as follows.
CAT I: Secondary electrical circuits connected to an electrical outlet through a
transformer or similar device.
CAT II: Primary electrical circuits in equipment connected to an AC electrical outlet
by a power cord (portable tools, household appliances, etc.).
CAT III: Primary electrical circuits of heavy equipment (fixed installations) connected
directly to the distribution panel, and feeders between the distribution panel and
outlets.
CAT IV: The circuit from the service drop to the service entrance, then to the power
meter and to the primary overcurrent protection instrument.
