Check Your Specs, CCA Is Different From Solid Copper
Risks of Copper-Clad Aluminum (CCA) Cables:
- 🚫 Illegal & Non-Compliant: Not approved for Ethernet by NEC/UL. Installations using CCA violate safety codes.
- 🔥 Fire Hazard: High resistance makes CCA unsafe for Power over Ethernet (PoE) – overheating risks.
- 📉 Poor Performance: Signal degradation over distance; unreliable for data transmission.
- 💔 Fragile Conductors: Brittle aluminum cores break during installation, leading to hidden failures.
- ⚡ Corrosion: Exposed aluminum oxidizes, creating non-conductive connections that degrade over time.
How to Spot CCA vs. Copper:
- 🕵️ Weight Test: CCA is lighter (aluminum weighs less than copper).
- ✂️ Scrape Test: Scrape conductor ends – silver beneath copper coating = aluminum.
- 📦 Label Lies: Ignore false "Cat5e/6" or "UL Certified" claims – these are deceptive.
Protect Your Network:
- ✅ Buy Bare Copper: Only trust reputable suppliers selling certified copper cables.
- ❌ Avoid Too-Good Prices: Extreme discounts often mean CCA scams.
- 🔍 Inspect Before Installing: Test cable flexibility and conductor material.
CCA has valid uses – voice coils, speakers – but NEVER for Ethernet.
Invest in quality – your network’s safety depends on it.

Simplified Guide to CCA Cables
What is CCA?
CCA (Copper-Clad Aluminum) cables have an aluminum core coated with copper. They’re cheaper but not compliant with official Ethernet standards, which require pure copper wires.
Key Concerns with CCA:
🔴 Safety Risks:
- 🚫 Fire Hazard: Higher resistance makes CCA dangerous for PoE (Power over Ethernet), especially with high-power devices.
- 💥 Durability Issues: Aluminum breaks easily during installation (punching into wall jacks, crimping connectors).
🔴 Performance Problems:
- 📉 Short Lifespan: Connections fail over time due to corrosion and metal fatigue.
- 📏 Limited Range: Often fails to work even at 30 meters (vs. the 100m standard for Cat6).
🔴 Misleading Claims:
- Many sellers falsely label CCA as "Cat6" or "UL Certified." It’s not suitable for structured wiring (in-wall installations).
When Might CCA Work?
- 🚧 Short, Temporary Use: Maybe for very short, non-PoE connections (e.g., a 3ft patch cable).
- ❗️ Never Trust It For:
- PoE devices (cameras, phones, WiFi access points).
- Permanent installations (walls, ceilings).
Real-World Advice:
1️⃣ Avoid CCA for Ethernet: It’s not worth the risk.
2️⃣ Buy Certified Copper: In the U.S., trusted brands like trueCABLE guarantee pure copper wiring.
3️⃣ Check Labels Carefully: If the price seems too good, it’s likely CCA.
Example:
“I tried CCA for my security cameras – the cables overheated and failed in weeks. Switched to copper, and no issues since.”
Bottom Line:
CCA cuts corners to save money. For reliable, safe networking, always use standards-compliant copper cables. 🔌
