About hangzhou Lingcheng Electric Co., Ltd.
Headquartered in Hangzhou, China, Hangzhou Lingcheng Electric Co., Ltd. is a specialized high-tech manufacturer dedicated to power connection, metering protection, and terminal distribution solutions. Operating under ISO9001 quality management, our modern production facilities integrate advanced injection molding and precision assembly to supply reliable, safe, and long-lasting electrical infrastructure products for power utilities, electrical wholesalers, and engineering contractors globally.
Metering Junction Box Categories
Metering Blocks
Our metering blocks provide secure, standardized wiring interfaces for single-phase and three-phase electricity metering, including anti-tamper, anti-misconnection and transparent bulletproof designs for high-security installations. As a metering block manufacturer, we support both standard catalog units and fully customized configurations for utility metering programs.
Household Terminals
Designed for centralized residential metering, our household terminals connect multiple single-phase meters — from 2-meter to 15-meter configurations — within a single compact terminal block, making them ideal for apartment buildings, multi-tenant housing and mixed-use developments. Available in bulk quantities for distributors and property/utility project suppliers.
Neutral Boxes
Our neutral boxes provide a dedicated, standardized neutral-line connection point for metering and distribution systems, helping installers maintain safe, code-compliant wiring across residential and commercial electrical panels — manufactured to the same quality standards as our full metering junction box range.
Distribution Terminals
Our distribution terminals are engineered for downstream power distribution after metering, supporting reliable current-carrying connections in switchgear, distribution boards and panel assemblies. Panel builders and EPC contractors rely on our distribution terminals for consistent quality across large-volume orders.
Built for Utility, Residential & Industrial Metering Projects
Lingcheng metering junction boxes are used across the full metering value chain: utility companies rely on them for meter installation, replacement and on-site calibration; property developers and contractors use household terminals and neutral boxes for multi-tenant metering in residential buildings; panel builders and EPC contractors specify our distribution terminals within switchgear and distribution board assemblies.
All products are manufactured under ISO9001 quality management and tested against international electrical safety standards, using high-grade flame-retardant PC material for greater durability and impact resistance compared to traditional bakelite housings. Anti-tamper sealing features and IP-rated enclosure options are available across our metering block and terminal ranges to meet utility anti-theft and outdoor protection requirements.

Frequently Asked Questions (FAQ)
Q: What is the minimum order quantity (MOQ) for metering junction boxes?
A: Our standard MOQ starts from 500 pcs per SKU. Smaller trial orders can be discussed for new distributors and first-time buyers.
Q: What is the difference between metering blocks, household terminals, neutral boxes and distribution terminals?
A: Metering blocks provide the primary wiring interface between the electricity meter and the power supply. Household terminals combine multiple single-phase meter connections for multi-tenant buildings. Neutral boxes provide a dedicated neutral-line connection point. Distribution terminals handle downstream power distribution after metering. Our sales engineers can help you select the right product for your project.
Q: Do you support OEM/ODM and custom specifications?
A: Yes — we support custom colors, branding, terminal configurations and packaging to match your project or regulatory requirements.
