Metering Cubicles

• A. Metering Cubicles
• B. Area Substation Cubicles
• C. Switchgear Cubicles
• D. Protection Relay

Answer: (A)

Metering cubicles are the enclosures that contain the instruments used to measure electrical quantities for billing and system monitoring, typically including meters and the associated current and potential transformers. This is what defines the space dedicated to metering, separating it from other functions in a substation or distribution system. Other cubicles have different roles: area substation cubicles house equipment for area substations, switchgear cubicles contain switching devices like breakers and disconnectors, and protection relay panels hold protective relays that trigger trips on faults. Because the question is asking for the term that identifies the enclosure used specifically for metering, the best match is Metering Cubicles.
