Product Overview

Single Phase Two Meter Terminal is a two-position metering block that puts both household meter connections of a duplex or two-unit property into one segregated body. Each position is electrically independent, with its own incoming and outgoing terminals, so two single-phase meters are fed from one unit instead of from two separate blocks bolted side by side in a crowded enclosure.

Two-household metering is where loose wiring starts to cost money. Two standalone terminal blocks mean two sets of jumpers, links and mounting hardware to buy and fit, and once the left unit and the right unit sit in the same box with no visible separation between them, an incoming L conductor for one dwelling is one careless lug away from landing on the wrong position.

This unit answers both problems in the structure itself. The two positions are built into one body with a clear left-and-right layout and the phase positions marked, so each dwelling's circuits stay on their own side of the block. The footprint comes in at roughly 30% below two separate blocks, the auxiliary parts list shrinks to one set, and an independent bypass at every position lets a meter be swapped live without cutting power to the neighboring unit.

Core Advantages

Four design points decide whether a two-household meter box can be wired cleanly and kept serviceable.

Two Independent Positions In One Segregated Body

The two meter connections are not two blocks bolted together - they are moulded into one body with a fixed left-and-right arrangement and the positions marked on the unit. An installer landing conductors for the left dwelling cannot drift onto the right position by eye, which is the cross-connection fault that is hardest to trace after the box is closed.

Independent Bypass At Every Position

Each position carries its own bypass mechanism. A meter is removed and replaced without opening any other circuit, so the swap is done live and the neighboring dwelling stays powered for the whole operation. For rental and duplex properties that means meter replacement no longer has to be scheduled as a two-household outage.

100 A Copper Busbar Standard

The main busbar is copper, rated 100 A as standard with 125 A and 160 A available as options, and it holds a low temperature rise under maximum current density. One bar feeds both positions instead of each meter pulling from its own set of joints, so the current path through the block is short and repeatable from unit to unit.

One Body Instead Of Two Blocks

Two standalone terminal blocks carry two sets of links, jumpers and mounting hardware. Consolidating them into one unit cuts the total panel footprint by roughly 30% and turns the auxiliary parts list for a two-household box into a single line item - the saving that matters most on a repeated duplex installation program.

Wire Cage Terminal vs Traditional Brass Terminal

The difference shows up at the first installation and at every meter swap after it.

Point Of Comparison	Segregated Two-Position Meter Terminal (This Unit)	Traditional Two Separate Terminal Blocks
Position separation	Two electrically independent positions moulded into one body, left and right	Two loose blocks with no built-in boundary between the two dwellings
Wiring confusion	Positions clearly marked, so each dwelling stays on its own side	Left and right are only as clear as the installer's labelling on the day
Meter replacement	Independent bypass at each position; hot swap with the other unit live	Both blocks opened together, or a two-household outage is scheduled
Auxiliary parts	One set of links, jumpers and fixings for the whole unit	Two complete sets bought, carried and fitted
Footprint	Approximately 30% below two standalone blocks	Two housings, two mountings and the jumper run between them
Current path	One 100 A copper busbar feeding both positions	Each meter fed through its own separate joints

Professional Production Process

Every unit follows the same five steps, and the electrical tests are recorded per batch.

Busbar stamping and forming - the copper bar is cut, punched and formed to the drawing for the 100 A / 125 A / 160 A rating on the order.

Surface treatment - the plating confirmed for the order is applied to the busbar before assembly, so the contact faces are protected before the unit is built up.

Housing moulding - the two-position segregated body is moulded in PC to the UL94 V-0 rating, with the position marking formed in.

Assembly - the busbar, both sets of terminals and the two independent bypass mechanisms are seated in register, and each bypass is operated to confirm it isolates only its own position.

Testing - contact resistance at ≤ 0.35 mΩ and dielectric strength at ≥ 3 kV / 1 min are checked on every unit, with results recorded per batch.

Material & Surface Treatment Options

Two material decisions are worth settling before the order is released.

Conductor And Busbar

The main conductor is a copper busbar, which is what keeps the temperature rise low at the 100 A standard rating and at the optional 125 A and 160 A ratings. The plating is confirmed at order stage against the drawing, so the contact faces stay stable in the environment the meter box actually sits in. A different busbar rating is set the same way.

PC Housing Rated UL94 V-0

The body is moulded in polycarbonate rated UL94 V-0 and the unit is rated from -40 °C to +85 °C. That range covers an outdoor meter enclosure in winter as well as the warmer interior of a cabinet in summer. Confirm the exact plastic grade if your specification names one.

Application Scenarios

Three places where a segregated two-position meter terminal earns its panel space.

Duplex And Two-Unit Rental Properties

Where two dwellings share one meter box, the unit keeps each household's incoming and outgoing circuits on its own marked side of one body. The auxiliary list is one set instead of two, the layout reads the same on every box of the program, and a meter swap on one dwelling never has to interrupt the other.

Main And Accessory Dwelling Configurations

A main house with an accessory unit on one supply is metered the same way as a duplex: two independent single-phase positions, one enclosure. The segregated layout keeps the two accounts visibly separate for inspection, and the 30% footprint saving leaves room in the enclosure for the meters themselves.

Small Retail And Two-Circuit Supply Metering

Small retail units and other two-circuit supply points use the same block as a compact metering interconnection module. Both circuits land on marked positions in one body, so the panel stays traceable long after the original installation crew has left the site.

Frequently Asked Questions

Q: What is a two-position single-phase meter terminal used for?

A: It merges the two meter connections of a duplex, two-unit rental or main-and-accessory dwelling configuration into one segregated body. Each position is electrically independent, so both households are metered from one compact unit instead of from two separate terminal blocks.

Q: How is wiring between the two dwellings kept from being confused?

A: The two positions are built into one body with a fixed left-and-right layout and the positions clearly marked. Each dwelling's incoming and outgoing conductors stay on their own side of the block, which removes the cross-connection risk of two unmarked blocks in one box.

Q: Can a meter be replaced without cutting power to the other unit?

A: Yes. Every position carries a dedicated independent bypass, so the meter is removed and replaced live while the neighboring dwelling stays powered. The bypass isolates only its own position and leaves the other circuit untouched.

Q: What current rating is available?

A: The main copper busbar is rated 100 A as standard, with 125 A and 160 A available as options. Contact resistance is ≤ 0.35 mΩ and the unit holds a low temperature rise under maximum current density. Confirm the rating against your load schedule before the order is released.

Q: What wire sizes does it accept?

A: Conductors from 1.5 mm² to 16 mm² in copper, covering the household incoming and outgoing ranges on a 230 V AC single-phase supply. Confirm the range against your meter panel schedule before the order is released.

Q: Do you support customization, and what is the MOQ?

A: Position marking, busbar rating and mounting details can be produced to your drawing under OEM or ODM terms. MOQ depends on the configuration and any tooling involved, and trial orders for a new project are negotiable, with volume pricing at higher tiers.

Q: How is it tested and shipped?

A: Contact resistance and dielectric strength are checked on every unit, with results recorded per batch. Units ship in standard export packaging and the nearest ports are Ningbo and Shanghai. Send your drawing and quantity for a quote within 24 hours.
