Blog > How to choose the right electrical wire for house?

Choosing the right electrical wires for your house enhances its safety and comfort. Electrical wires act like bridges that carry electricity from the main panel to the switchboards and appliances. The wrong selection of electrical wires may cause overheating, short circuits, fire hazards, and voltage drops. To avoid these, we recommend choosing the right wire for your home. In this blog, we have listed some essential factors to consider when selecting the right electrical cable for home for increased safety:

Understanding Wire Basics for Indian Homes

  • Wire Gauge (AWG): Residential electrical wiring in India uses the American Wire Gauge (AWG) system to measure wire thickness. Lower AWG numbers mean thicker wires that can handle more electrical power.
  • Wire Insulation: Wire insulation is important because the outer layer protects the inner conductor and prevents accidents. PVC insulation is commonly used indoors in India. Opt for wire that resists water damage in moisture-prone areas like bathrooms and wash areas.
  • Certification: You need to ensure that the electrical cable for your home has the Bureau of Indian Standards (BIS) certification. This certification means it meets safety and quality standards.

Factors to consider

  • Circuit Load: Before picking a wire size, it’s important to know how much electricity (amps) devices on the circuit will use simultaneously. Ask a professional electrician for the recommended amperage for each circuit in your home.
  • Wire Length: You should first measure the required length of the wire. Longer wire or wire covering longer distances will need to be thicker to minimize voltage drop.
  • Number of Conductors: Most home wires in Residential electrical wiring have two or three wires inside. A two-wire cable has a “hot” wire for electricity and a “neutral” wire for returning it. A three-wire cable adds a “ground” wire for safety.

Types of Electrical Wires

Now that you have understood the factors, here are a few types of electrical wires and their purposes:

  • Non-Metallic Sheathed Cable (NM): These cables are a common choice for Residential electrical wiring. They have a plastic covering with two or more insulated wires and a ground wire.
  • Underground Feeder Cable (UF): UF is the perfect option if you need wire for a comparatively harsher environment. They are waterproof and made especially for outdoor or underground use.
  • Armored Cable (AC): These cables have a very flexible metallic covering that provides extra protection from potential damage.
  • Thermostat Wire: These low-voltage wires are generally used to connect HVAC systems and can handle temperature fluctuations.

These factors might look small, but they will make a huge difference in your everyday life. With Qfix Wires & Cables, your Residential electrical wiring is in safe hands.
