Cat2 Meter measures what?

Cat2 Meter measures what?

• A. Single-phase receptacles
• B. Three-phase distribution
• C. DC circuits
• D. Electrical transformers

Answer: (A)

Cat II refers to measurements made on circuits that are connected to a single-phase outlet or other plug‑in loads, such as wall receptacles, extension cords, and portable appliances. This rating defines where the instrument is intended to be used and the level of transient protection it must withstand in those environments. Therefore, a Cat II meter is designed for measuring at single‑phase receptacles. It isn’t intended for higher-stress environments like three‑phase distribution in panels (which fall under Cat III/IV) or for components such as transformers that live in those higher-category environments. So the best fit for the scenario described by Cat II is measuring at single‑phase receptacles.
