Definition of the overvoltage categories
Measurement category II: Measurements on the power circuits that have a direct plug connection
to the low voltage network. Normal short-circuit current < 10 kA.
Measurement category III: Measurements within the building installation (stationary consumer
devices with non-plug-in connection, distributor connection, permanently installed equipment in
the distributor).
Normal short-circuit current < 50 kA.
Measurement category IV: Measurements at the source of the low voltage installation (meters,
mains connection, primary overcurrent protection). Normal short-circuit current >> 50 kA.
When establishing the measurement category for a combination of test probe assembly and
measuring instrument, the lowest category, either of the test probe assembly or the measuring in-
strument, always applies.
