• Measurement Category III is for measurements performed in
the building installation at the distribution level. This category
refers to measurements on hard-wired equipment such as
equipment in fixed installations, distribution boards, and
circuit breakers. Other examples are wiring, including cables,
bus-bars, junction boxes, switches, socket-outlets in the fixed
installation, and stationary motors with permanent connections
to fixed installations.
• Measurement Category IV is for measurements performed at
the primary electrical supply installation (<1,000 V).
Examples include electricity meters and measurements on
primary overcurrent protection devices and on ripple control
units.
