CAT I: FormeasurementsoncircuitsnotdirectlyconnectedtotheAC
supply wall outlet such as protected secondaries, signal level,
andlimitedenergycircuits.
CAT II: For measurements performed on circuits directly connected to
the electrical distribution system. Examples are measurements
onhouseholdappliancesorportabletools.
CAT III: For measurements performed in the building installation at
the distribution level such as on hardwired equipment in xed
installation and circuit breakers.
CAT IV: For measurements performed at the primary electrical supply
(<1000V) such as on primary overcurrent protection devices,
ripplecontrolunits,ormeters.
