Project Overview

Scope: Installed and routed 100 feet of NM-B 12/2 cable to extend an existing 20-amp branch circuit for outlets.
Cable type: NM-B Romex 12/2 (12 AWG copper, hot/neutral/ground) suitable for 20A circuits serving power outlets and high-current devices.
Team: Lead electricians Anthony Vazquez, Matt Silber, and Chris Rogers, with support from an electrical assistant to ensure an efficient, organized install.
Location: Concord, NC (serving the greater Concord service area from our Charlotte branch).
Categories: Outlets & Switches; Outlet Installation & Repair.

This extension provides the homeowner with additional reach on an existing 20-amp outlet circuit, helping power tools, kitchen appliances, and other equipment that benefits from a dedicated 20A circuit with 12-gauge wiring.

What We Installed and How It Helps

100 ft of 12/2 NM-B: Properly sized 12 AWG copper wiring maintains safe ampacity for 20-amp circuits, reducing voltage drop over longer runs.
Smart routing and protection: Cable paths were planned to avoid heat sources and sharp edges, with mechanical protection and secure fastening per code.
Junction box as needed: Any required junction box used for splicing was appropriately enclosed and covered to maintain accessibility and safety.
Clean finish: We kept the work area tidy and clearly identified the extended circuit for future service or additions.

Whether you’re supporting garage tools, workshop equipment, or kitchen devices, a properly extended 20A circuit with 12/2 wiring helps deliver reliable power and reduce nuisance trips.

Code-Compliant From Start to Finish

Our electricians follow the National Electrical Code (NEC) and local Concord requirements on every outlet and circuit project. For this service, we focused on:

Correct conductor sizing: 12 AWG copper conductors dedicated to a 20-amp circuit.
Secure cabling: Proper support, protection through framing, and safe clearances.
Accessible splices: All splices contained within listed junction boxes with covers.
Verification: Continuity and grounding checks to confirm a safe, dependable extension that aligns with the existing 20A overcurrent protection.

The result is a neat, durable installation that’s serviceable and inspection-friendly.
