1. Non-Metallic Sheathed Cable (NM Cable) or Romex: This is the most common type of electrical wiring used in homes. It consists of two or more insulated conductors and a bare ground wire, all wrapped in a plastic sheath. It is used for general electrical wiring in walls, floors, and ceilings.
  2. Armored Cable (AC): This type of wiring is also known as BX cable. It has a flexible metal sheath around the conductors, providing better protection against physical damage and fire. It is commonly used for wiring in older homes and in areas where wiring may be exposed to damage.
  3. Underground Feeder Cable (UF Cable): This type of wiring is used for outdoor wiring and in areas that are exposed to moisture. It has a solid plastic core with an outer sheath that is resistant to moisture and can be buried directly in the ground.
  4. Low Voltage Wiring: This type of wiring is used for circuits that run at a voltage of less than 50 volts, such as doorbells, thermostats, and landscape lighting. It is typically smaller in size than regular wiring and is not a hazard to touch.
  5. Coaxial Cable: This type of wiring is used for cable TV, internet, and telephone connections. It consists of a center conductor surrounded by insulation, a metal shield, and an outer jacket. It provides better signal quality and protection against interference.
  6. Fiber Optic Cable: This type of wiring uses light to transmit data instead of electricity. It consists of thin strands of glass or plastic that carry signals over long distances at high speeds. It is commonly used for high-speed internet connections and digital communication.
