Per IEC1010 Measurement Installation Category
MEASUREMENT CATEGORY I: Equipment of OVERVOLTAGE CATEGORY I is equipment for connection to
circuits in which measures are taken to limit the transient overvoltages to an appropriate low level. Note
– Examples include protected electronic circuits.
MEASUREMENT CATEGORY II: Equipment of OVERVOLTAGE CATEGORY II is energy-consuming
equipment to be supplied from the fixed installation.
Note – Examples include household, office, and laboratory appliances.
MEASUREMENT CATEGORY III: Equipment of OVERVOLTAGE CATEGORY III is equipment in fixed
installations.
Note – Examples include switches in the fixed installation and some equipment for industrial use with
permanent connection to the fixed installation.
MEASUREMENT CATEGORY IV: Equipment of OVERVOLTAGE CATEGORY IV is for use at the origin of the
installation.
Note – Examples include electricity meters and primary over-current protection equipment
