The Metering Distribution Box is a pre-assembled electrical enclosure that combines power distribution with accurate energy metering in a single, compact unit. It integrates circuit breakers, current transformers (CTs), and digital or electromechanical meters to measure voltage, current, power, and energy consumption per circuit or tenant.

FAQs
Are your meters certified for billing purposes?
Yes-meters comply with IEC 62053 and can be supplied with calibration certificates upon request.
Can I read data remotely?
Absolutely. Smart meter versions support RS485/Modbus, LoRaWAN, or Wi-Fi for integration with energy management systems.
Do you provide wiring diagrams?
Yes-each order includes clear English wiring diagrams and CT connection instructions.
Is the box suitable for outdoor use?
Standard model is IP54 (indoor). We offer IP65 outdoor versions with sealed gaskets and UV-resistant materials.
What's the warranty?
24 months on enclosure and wiring; meter warranty per manufacturer (typically 18–24 months).
