To ensure safe operation of measurement devices, IEC 61010
establishes safety standards for various electrical environ­ments, categorized as CAT II to CAT IV, and called measure­ment categories.

CAT II: Primary electrical circuits in equipment connected to

an AC electrical outlet by a power cord (portable tools,
household appliances, etc.)
CAT II covers directly measuring electrical outlet re­ceptacles.

CAT III:Primary electrical circuits of heavy equipment (fixed

installations) 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 en-

trance, and to the power meter and primary overcur­rent protection device (distribution panel).

Using a measurement device in an environment designated
with a higher-numbered category than that for which the de­vice is rated could result in a severe accident, and must be
carefully avoided.

Use of a measurement instrument that is not CAT-rated in
CAT II to CAT IV measurement applications could result in a
severe accident, and must be carefully avoided.
