Category II, Pollution Degree 2. Category II includes
local level, appliance, portable equipment, etc., with
transient overvoltages less than Overvoltage
Category III. Probe assemblies to be used for mains
measurements shall be rated as
appropriate for measurement Category III according
to IEC 61010-31 and shall have a voltage rating of at
least the voltage of the circuit to be measured.
Measurement category III (CAT III) is applicable to
test and measuring circuits connected to the
distribution part of the building's low-voltage mains
installation.
