Products Overview
A compact four-in-one assembly for concentrated single-phase residential metering.
The Single Phase Four Meter Terminal consolidates four independent single-phase meter interfaces into one integrated moulded body, replacing the four separate terminal blocks that would otherwise be fitted side by side. In a small residential meter box, that consolidation cuts the enclosure footprint by up to 40% and removes the crossing cable runs that four blocks force onto a narrow backplate.
The space is recovered in the depth of the box rather than across its face. Conductors are arranged to run straight in from the back, which keeps the four circuits separated household by household and leaves the wiring readable at inspection. Each meter position carries its own bypass circuit configuration, so a meter can be exchanged without cutting supply to the other three households.
The housing is moulded from high-polymer polycarbonate with self-extinguishing flame retardancy and zero moisture absorption, giving steady performance from -40 °C to +85 °C in unheated service rooms, basements and humid coastal installations.
"Four meters have to fit where there was only ever room for cable. Bringing the four connection points into one body is what buys the space back." - Lingcheng Engineering Team

Core Advantages
Four points that decide whether a crowded residential box can be closed up and signed off.
Compact Four-In-One Body
One assembly replaces four individual terminal blocks and reduces the enclosure footprint by up to 40%. On a narrow box that is the difference between a workable layout and one that cannot be assembled at all.
Depth-Oriented Layout
The assembly is arranged to use the back of the enclosure instead of its width, so conductors run straight into the terminals rather than across the face of the box. The finished wiring stays orderly and is quick to check.
Bypass At Every Meter Position
Each of the four positions has its own autonomous bypass configuration, so a meter can be exchanged without interrupting supply to the neighbouring households. No temporary rewiring, and no visits to three other homes.
Stable In Damp Service Rooms
High-polymer polycarbonate gives self-extinguishing flame retardancy, zero moisture absorption to prevent mildew, and steady performance from -40 °C to +85 °C, which suits unheated service rooms, basements and humid coastal sites.
Wire Cage Terminal vs Traditional Brass Terminal
What an installer trades when four conventional brass terminal blocks are replaced by a single cage clamp assembly.
| Comparison Dimension | Wire Cage Terminal | Traditional Brass Terminal |
| Material Cost | Lower, moulded housing with formed clamps | Higher, solid brass blocks |
| Installation Space | One body, up to 40% less enclosure footprint | Bulky, four blocks across the width |
| Assembly Speed | Quick assembly, standardized positions | Cumbersome, four blocks to align |
| Connection Stability | Stable, firm cage clamp fixing | Stable |
| Weight | Lighter | Heavier |
| Meter Exchange | Per-position bypass, neighbours unaffected | Requires separate isolation |
| Customization | OEM / ODM per drawings | Limited |
| Overall Cost-Effectiveness | Superior | Higher total cost |
Professional Production Process
The sequence this assembly runs through, from moulding to tested export packing.
Housing moulding - the polycarbonate body is moulded to finished dimensions.
Metal part forming - cage clamps and screw terminals are formed from sheet to drawing.
Insert assembly - terminals are seated and fixed into the moulded body, all four positions in register.
Contact resistance test - verified at ≤0.35 mΩ.
Dielectric strength test - verified at ≥2.5 kV for 1 minute.
Bypass and dimension check - every position checked, then sampling and export packing.
Test results are recorded per batch, so a repeat order performs the same as the sample you approved.
Material & Surface Treatment Options
Two material decisions you can set before the order is placed.
Polycarbonate Housing
1.High-polymer polycarbonate, UL94 V-0 self-extinguishing.
2.Zero moisture absorption, so no mildew in damp service rooms.
3.Dimensionally stable from -40 °C to +85 °C.
4.High impact resistance for site handling and export transit.
Terminal And Conductor Parts
1.Cage clamp or tubular screw termination.
2.Sized for copper conductors from 1.5 mm² to 16 mm².
3.Contact resistance ≤0.35 mΩ, rated 60 A with 80 A and 100 A available.
4.Short-time withstand current 5 kA / 1 s.
Surface treatments: original surface, nickel plating or tin plating, with custom coatings produced to customer requirements.
Application Scenarios
Where this assembly earns its place on site.
Residential Meter Box Retrofit
Replacing four loose blocks in an existing single-family or small residential box, where the enclosure is already fixed, the mounting space is tight, and the cable entries cannot be moved.
Multi-Family And Apartment Metering
Concentrated single-phase metering in apartment blocks and multi-family housing, where incoming and outgoing distribution has to stay separated per household and a meter exchange must not disturb the neighbours.
Small Commercial And Shallow Panels
Small commercial metering rooms and light industrial distribution boards, wherever four single-phase circuits have to be terminated inside a shallow enclosure.
Frequently Asked Questions
Common questions from contractors and distributors specifying this terminal.
Q: What is a four meter terminal used for?
A: It is one assembly carrying four independent single-phase meter interfaces. It is specified where four separate terminal blocks would not fit, because consolidating the connection points into one integrated body cuts the enclosure footprint by up to 40% and keeps the four circuits separated household by household.
Q: What conductor sizes and termination styles are supported?
A: Copper conductors from 1.5 mm² to 16 mm², terminated by cage clamp or tubular screw. The termination style is fixed at production, so confirm it when ordering.
Q: What happens when one meter has to be replaced?
A: Each of the four positions has its own autonomous bypass configuration, so the meter can be exchanged without cutting supply to the other three households.
Q: What housing material is used, and are surface treatments available?
A: The housing is high-polymer polycarbonate rated UL94 V-0, self-extinguishing with zero moisture absorption, and stable from -40 °C to +85 °C. Metal parts are available with original surface, nickel plating or tin plating, and custom coatings can be produced to your specification.
Q: Do you support custom specifications, and what is the MOQ?
A: Yes. Rated current (80 A and 100 A), termination style and mounting configuration can be produced to your drawing under OEM or ODM terms. Standard MOQ is 5,000 pieces per SKU, with smaller trial orders negotiable for new projects and volume pricing at higher quantity tiers.
Q: What is the quality guarantee, packaging and delivery port?
A: All units carry a 12 to 24 month quality guarantee from shipment. Every batch is tested for contact resistance at ≤0.35 mΩ and dielectric strength at ≥2.5 kV for one minute, with results recorded per batch. Standard export packaging protects the moulded bodies in transit, and the nearest ports are Ningbo and Shanghai. Send your drawing with the required quantity for a reply within 24 hours.
