Measurement categories (Overvoltage catego-
ries)
To ensure safe operation of measurement instru-
ments, IEC 61010 establishes safety standards for
various electrical environments, categorized as
CAT I to CAT IV, and called measurement catego-
ries. These are defined as follows.
Higher-numbered categories correspond to electrical
environments with greater momentary energy. So a
measurement device designed for CAT III environ-
ments can endure greater momentary energy than a
device designed for CAT II.
Using a measurement instrument in an environment
designated with a higher-numbered category than
that for which the instrument is rated could result in a
severe accident, and must be carefully avoided.
Never use a CAT I measuring instrument in CAT II,
III, or IV environments.
CAT I Secondary electrical circuits connected to an
AC electrical outlet through a transformer or
similar device.
CAT II Primary electrical circuits in equipment con-
nected 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 from the distribu-
tion panel to outlets.
CAT IV The circuit from the service drop to the service
entrance, and to the power meter and primary
overcurrent protection device (distribution panel).

The measurement categories comply with the Over-
voltage Categories of the IEC60664 Standards.
