Understanding Wire and Cable Technology

What Are Electrical Wires and Cables?

• Wires are single conductors of electricity, usually made of copper or aluminum.
  
  
• Cables are multiple wires grouped together in a single sheath for organized power transmission.

Types of Wires and Cables

1. Non-Metallic (NM) Cables – Common in residential buildings.
   
   
2. Underground Feeder (UF) Cables – Used for underground installations.
   
   
3. Coaxial Cables – For data and TV connections.
   
   
4. Armored Cables – For industrial and outdoor use.
   
   
5. Flexible Cables – Used in appliances and movable electrical connections.

Choosing the Right Wire and Cable

• Current Rating – Match the cable size to the power demand.
  
  
• Insulation Type – Ensure it suits the environment (heat-resistant, waterproof, etc.).
  
  
• Voltage Rating – Check compatibility with the intended power supply.
