Cat3 Meter measures?

Cat3 Meter measures?

• A. 3 phase distribution and single phase lighting equipment
• B. Electronics only
• C. Water quality
• D. Mechanical load

Answer: (A)

Cat3 meters are designed for testing distribution‑level electrical wiring inside buildings, including three‑phase distribution circuits and single‑phase lighting circuits. The Cat3 rating reflects the types of circuits and transient voltages found on these distribution runs, such as feeders and lighting, making it suitable for measuring electrical parameters in those areas. It wouldn’t be used for water quality, mechanical loads, or electronics‑only contexts, which are outside the scope of distribution‑level electrical testing.
