SEPCO NS63 Aluminum Gooseneck Service Entrance Head, 3-Conductor, 8 AWG-4/0 AWG

The SEPCO NS63 Aluminum Service Entrance Head is a weatherproof fitting that brings overhead service drop conductors into a raceway system while keeping moisture out of the enclosure at one of the most exposed points on an electrical installation. Built from durable aluminum with a gooseneck-style profile, the NS63 is designed for (3) conductors and is available in two wire size configurations covering the 8 AWG-4/0 AWG range: 8 AWG-1 AWG or 1/0 AWG-4/0 AWG, matching the conductor sizes commonly used on single-phase overhead service drops feeding residential and light commercial properties. The gooseneck entry directs incoming conductors downward at the point of entry, a standard configuration for service entrance caps used throughout the electrical trade to keep rain and moisture from tracking into the service raceway.

Key Features

  • Conductor Capacity: Accommodates (3) conductors, offered in two wire size options — 8 AWG-1 AWG or 1/0 AWG-4/0 AWG — to match typical overhead service entrance wiring runs.
  • Durable Construction: Aluminum body resists corrosion and weathering, suited for continuous outdoor exposure at the top of the service raceway.
  • Service Entrance Head Design: Gooseneck-style entry point allows overhead service drop conductors to enter the raceway while shedding water away from the connection point.
  • Model Designation: Identified within the SEPCO NS series as model NS2, cross-referenced to SKU NS63 for ordering and inventory purposes.
  • Lightweight Profile: Aluminum construction keeps the fitting lightweight relative to comparable cast fittings, simplifying handling and mounting at height.
  • Multi-Conductor Entry: Individual conductor openings keep each of the (3) conductors separated as they pass into the raceway, supporting neat, code-familiar terminations.

Typical Applications

  • Overhead Electrical Service Entrances
  • Weatherproofing Raceway Entry Points
  • Residential and Light Commercial Service Drops
  • Meter Base and Service Conductor Terminations

Why SEPCO?

SEPCO builds the NS63 service entrance head from aluminum for long-term outdoor durability at one of the most weather-exposed points in an electrical system, offering both 8 AWG-1 AWG and 1/0 AWG-4/0 AWG wire size configurations to fit a range of overhead service entrance jobs. Electrical contractors rely on SEPCO fittings like this service head for dependable, code-familiar overhead service entrance connections on residential and light commercial projects, and the aluminum construction helps the fitting hold up to years of sun, rain, and temperature swings at the service riser without adding unnecessary weight to the raceway.

SEPCO NS2 – Frequently Asked Questions

1) Which SEPCO NS63 wire size option do I need for a 200 amp overhead service with 2/0 aluminum triplex?
Order the 1/0 AWG to 4/0 AWG version, MPN NS7A. The NS63 service entrance head comes in two conductor ranges: NS2 covers 8 AWG through 1 AWG, and NS7A covers 1/0 AWG through 4/0 AWG. A 2/0 conductor falls in the NS7A range, so the smaller NS2 head will not take it.
2) How many conductors does the SEPCO NS63 service head accept?
Three. The NS63 is built for (3) conductors, with individual openings that keep each conductor separated as it enters the raceway. That matches a typical single-phase overhead service drop, two hots and a neutral. If you are bringing in more than three conductors, this head is not the right fitting.
3) Is an aluminum service entrance head OK for permanent outdoor use at the top of a riser?
Yes. The NS63 body is aluminum, chosen for continuous outdoor exposure at the service riser where the fitting sees sun, rain and temperature swings year round. It is also lighter than comparable cast fittings, which matters when you are setting it at height on a ladder or bucket.
4) What does the gooseneck design on the NS63 actually do?
The gooseneck profile turns the conductor entry downward so water runs off instead of tracking down the wires into the service raceway and enclosure. It is the standard shape for a service cap on an overhead drop, and it is why the head belongs at the very top of the riser above the service point.
5) Is the SEPCO NS63 suitable for a residential service upgrade, or is it a commercial-only fitting?
Both work. The NS63 is aimed at residential and light commercial overhead service drops, including new construction and service upgrade jobs where you are replacing the riser and meter base. The 8 AWG to 4/0 AWG span across the two versions covers the conductor sizes normally used on single-phase drops feeding houses and small commercial buildings.
6) Where does a service entrance head like the NS63 sit in the installation?
At the top of the service raceway, above the point where the utility drop attaches. Service conductors come out of the head, drip loop down, and connect to the utility triplex; the raceway then runs down to the meter base and service equipment. The head is the weatherproofing at that entry, not a connector or a splice point.
