What is the AC voltage rating required on an electric meter badge?

The AC voltage rating required on an electric meter badge must be included as part of the essential information provided by the manufacturer. This rating indicates the maximum voltage the meter can safely handle, which is critical for the safe operation and for users to understand the electrical parameters of the device. Including the AC voltage rating helps ensure that the meter is used within its intended specifications, thereby promoting safety and reliability in electrical measurements.

While the other options suggest varying degrees of importance regarding the inclusion of voltage ratings, they do not adhere to the standardized requirements that necessitate this information as fundamental. The presence of the AC voltage rating on the meter badge empowers users to make informed decisions and establishes compliance with safety regulations.
