Heat Dissipation: Electricity meters generate heat during operation; enclosures must feature ventilation holes or thermally conductive structures to prevent excessive internal temperatures.
Sealing: Enclosures must prevent the ingress of dust and moisture and pass airtightness tests, making them suitable for humid or dusty environments.
Installation Compatibility: Enclosure dimensions must match the meter's internal components, while also accommodating features such as wiring ports and mounting brackets.
Environmental Requirements: Some countries enforce strict regulations regarding the recyclability of enclosure materials and the content of hazardous substances (e.g., RoHS directives).
