How to wire the meter in the main distribution box

Wiring a residential electric meter involves connecting the utility's line conductors to the meter socket, then routing the load side to the main distribution panel with proper grounding and safety precautions.Safety FirstBefore starting, disconnect the main power supply and coordinate with your local utility to ensure the service is de-energized. Working on a meter socket involves high voltage and can be fatal if mishandled, so a licensed electrician should perform or supervise the installation. Obtain any required permits from your local Authority Having Jurisdiction (AHJ) to comply with code requirements .Components and Wire TypesMeter socket: Holds the utility meter and separates the Line Side (always energized) from the Load Side (feeds the home panel).Service entrance cable: Connects the meter to the main panel. Common types include SEU (unarmored), SER (round), or USE/USE-2 for underground installations .Main panel: Contains breakers and bus bars for distributing electricity to circuits.Grounding system: Includes a ground rod or electrode connected to the neutral bar in the main panel .Wiring StepsMount the meter socket securely on an exterior wall, typically 5 feet above ground, ensuring easy access for utility personnel .Route the service entrance cable from the weatherhead or utility drop into the top knockout of the meter socket using a 2-inch conduit .Connect the Line Side conductors (usually black and red) from the utility to the top lugs of the meter socket. These wires remain energized until the utility disconnects the service .Connect the Load Side conductors from the bottom lugs of the meter socket to the main breaker terminals in the distribution panel. The neutral conductor bypasses the meter jaws and connects directly to the neutral bus bar .Grounding: Connect the bare or green-insulated grounding conductor to a terminal bonded to the metallic enclosure and ensure continuity with external ground rods .Neutral bonding: In the main panel, bond the neutral bar to the panel chassis only if it is the main service panel. Subpanels must keep neutral and ground separate to prevent circulating currents .Torque and secure connections: Use a calibrated torque wrench to tighten all terminals to manufacturer specifications. Apply anti-oxidant compound for aluminum conductors to prevent corrosion .Install the meter: Once all connections are verified, the utility can install the meter. Turn on the main breaker and test the system for proper operation .Color CodingHot wires: Black or redNeutral: White or grayGround: Green or bare copper Final NotesAlways follow the manufacturer's wiring diagram and local electrical codes. Improper wiring can cause reversed polarity, grounded conductor faults, or fire hazards. Professional inspection ensures safety and compliance .
