Electrical MC Cable Upgrade and Conduit Installation in Siler City, NC

Touchstone Electric’s Raleigh branch completed a code-focused wiring upgrade for homeowner Diana Blanco in Siler City, NC. On July 23, 2025, our technician Brad Williams performed an Electrical Repairs & Troubleshooting service to improve protection, durability, and compliance for wiring routed from the main panel to the crawlspace and along metal joists.

The project included installing liquid-tight flexible conduit from the exterior main panel to the crawlspace and converting existing Romex (NM) to MC 12/2 cable so the wiring could be safely strapped to metal framing. This upgrade provides a robust, long-lasting solution for a space that can be damp and subject to physical contact.

Project Overview

We replaced vulnerable NM cable in the crawlspace with metal-clad cable and added a liquid-tight pathway where wiring transitions from outdoors to the interior. By combining liquid-tight flex with MC cable, the installation now delivers enhanced moisture resistance, abrasion protection, and secure fastening to metal joists—key requirements for a safe and professional result.

Location: Siler City, NC (serviced by our Raleigh branch)
Scope: Conduit installation from the main panel to the crawlspace; conversion from Romex to MC cable
Technician: Brad Williams
Category: Electrical Repairs & Troubleshooting

What We Installed

Liquid-Tight/Flex Conduit (3/4"): Sealproof flexible conduit, with appropriate connectors and LBs as needed, to protect conductors from the exterior panel into the crawlspace.
MC 12/2 Cable (approx. 50 ft): Durable metal-clad cable for 20-amp branch circuits, ideal for securing to metal joists and resisting physical damage.
Qualified Labor: Lead electrician supported by an apprentice to ensure an efficient, detail-driven installation.

Why This Upgrade Matters

Protection where it counts: Liquid-tight flex safeguards conductors in outdoor-to-indoor transitions and damp-prone crawlspaces.
Metal framing readiness: MC cable is designed to be strapped to metal joists, offering a sturdy, code-compliant wiring method.
Longevity and safety: Enhanced abrasion resistance and secure routing help reduce future maintenance and nuisance faults.
Cleaner serviceability: Clearly defined pathways and labeling make future troubleshooting more straightforward.

Our Installation Process

Our team planned an efficient route from the exterior main panel into the crawlspace, installed the liquid-tight flex with the correct fittings, and transitioned to MC cable where appropriate. We securely strapped the MC cable along the metal joists at proper intervals, used the correct connectors, and ensured smooth, protected entries at all terminations. Final checks included continuity and operation testing to verify a safe, dependable result.
