Custom Outdoor Metering & Distribution Cabinet for Residential Power System

This project involves the design and manufacturing of a custom outdoor metering and distribution cabinet system for a residential power supply application. A total of 198 units were planned, with the first sample enclosure produced for approval.

The cabinet integrates energy metering, circuit protection, and distribution functions in a single enclosure, ensuring safe, organized, and efficient power management for multi-user installations.

Designed in accordance with national standards, the enclosure provides reliable performance in outdoor environments with strong emphasis on electrical safety, moisture protection, and long-term durability.

The client required a standardized outdoor metering cabinet with the following specifications:

• Application: Residential power distribution and metering system
• Installation: Outdoor wall-mounted installation
• Structure: Multi-compartment cabinet for metering and switching
• Electrical System: Three-phase four-wire (A, B, C, N)
• Protection: Moisture-proof, insulated, and safe grounding system
• Wiring: Organized internal wiring with labeling and cable management
• Safety: Independent compartments for metering and switching
• Grounding: Reliable earthing system with ≤1Ω resistance
• Access: Lockable structure with separate access for utility and user
• Expansion: Reserved space for SPD installation
• Cable Entry: Bottom sealed cable entry only

Based on the system design and safety requirements, a customized enclosure solution was developed:

• Multi-functional design integrating metering, protection, and distribution
• Segmented internal structure for improved safety and management
• Dedicated compartments for meter section, incoming, and outgoing circuits
• Bottom cable entry with sealing to prevent water ingress
• Reserved SPD installation space for surge protection
• Organized wiring layout with clear labeling for each circuit
• Separation of grounding and neutral systems to meet electrical standards
• Moisture-proof internal design to ensure insulation reliability
• Lockable access control system for different user levels

• Application: Residential metering and distribution system
• Installation: Outdoor wall-mounted
• Electrical System: Three-phase four-wire (A/B/C/N)
• Protection Design: Moisture-proof and insulated
• Cable Entry: Bottom entry with sealing protection
• Internal Structure: Multi-compartment design
• Grounding Resistance: ≤1Ω
• SPD: Reserved installation position
• Access Control: Multi-level locking system
• Quantity: 198 units (project total)

• Laser cutting and panel fabrication
• CNC bending and structural forming
• Welding and assembly
• Surface treatment and finishing
• Internal installation and wiring layout
• Final inspection and quality control

The final solution delivers a reliable and standardized metering and distribution system suitable for residential power applications.

With a well-organized internal layout, strong safety design, and outdoor durability, the enclosure ensures efficient installation, easy maintenance, and long-term stable operation.
