Product Overview
Managing individual electricity metering in modern multi-tenant residential towers, high-rise apartments, and commercial complexes has traditionally been a space-consuming and labor-intensive challenge. Conventional setups require numerous separate meter enclosures, leading to cluttered panel layouts and complicated, error-prone wiring procedures.
This high-density consolidated terminal hub addresses these issues by integrating fifteen fully isolated independent connection stations into a single compact structural unit. Rated for heavy-duty main busway applications, it enables utility operators to consolidate up to fifteen individual subscriber connections within a unified footprint, reducing overall mounting space by as much as 50% while significantly streamlining the deployment of automated meter reading (AMR) systems.
Engineering Highlights
Impact-Resistant Polycarbonate Housing – Moving away from conventional brittle plastics that tend to crack under installation stress and absorb moisture over time, the entire enclosure is injection-molded from premium-grade polycarbonate polymer. This material delivers exceptional impact strength, zero water absorption to prevent internal mildew formation, and a UL94 V-0 flame-retardant rating for maximum fire safety.
Hot-Swap Bypass Protection – Each meter position features an independent physical bypass circuit. This critical innovation allows field technicians to remove, test, or replace a faulty electricity meter while the system remains energized-without disconnecting any main distribution cables or interrupting power supply to neighboring tenants.
Versatile Combination Slot Terminals – All wire-clamping ports and bus terminals utilize an advanced combination slot screw design. Installation crews can work with either flathead or Phillips screwdrivers, achieving high-torque, vibration-resistant connections without the risk of screw head stripping.
High-Capacity Tin-Plated Copper Busbar – The electrical backbone consists of a heavy-gauge tin-plated copper busbar rated at 300A standard capacity, expandable up to 500A. This substantial copper cross-section minimizes contact resistance to ensure cool operation even when all fifteen load stations are running simultaneously at full capacity.

Flexible Power Distribution Configurations
The main incoming copper busbar features an adaptive segmented design, allowing contractors to divide the fifteen-station array into two or three isolated power supply zones. This structural flexibility supports selective load grouping or dual-supply redundancy configurations, making the unit particularly well-suited for municipal housing developments, university dormitory complexes, and industrial park staff accommodations.
