CAT
IV
Measurement Category IV is applicable to test and measuring circuits
connected at the source of the building’s low-voltage MAINS installation.
This part of the installation is expected to have a minimum of one level of
over-current protective devices between the transformer and connecting
points of the measuring circuit.
Due to these high short-circuit currents (above 50kA) which can be
followed by a high energy level, measurements made within these
locations are extremely dangerous. Great precautions shall be made to
avoid any chance of a short circuit.
Examples of CAT IV are measurements on devices installed before the
main fuse or circuit breaker in the building installation.
