Must-know basics of electricals for an Indian home buyer- part I

Electricals in your home must be taken seriously. A home buyer must be aware of what makes an electrical system in the apartment, and how to make sure that every member of the family is safe.

With knowledge about the basics of electricals, one can be better equipped to make sure electrical fires or electrocution are kept at bay.

One needs to know how ‘short circuit’, and make sure that your home is completely protected from any form of electric fire or threat of electrocution.

Electrical safety needs to be assessed with a great sense of responsibility. While the builder is responsible for it, and the ‘occupation certificate’ is issued only once the builder follows all the measures to secure safety, it is still necessary to err on the side of caution.

Electricity is inherently a dangerous thing, and we cannot see really witness how electricity flows. This can result in hurt or accidents, hence the need to understand the basics of electricals, safety-related measures, and equipment being provided to us by residential builders.

Why is electrical safety important?

  • The human body is a ‘conductor’ of electricity, which means it can cause damage to the human body upon contact
  • Electricity is safe so far as it flows in the intended path. We must ensure there is no Direct or Indirect contact of the human body with electricity, and we remain protected

Direct or Indirect Contact

 basics of electricals - Ensure there is no live wire contact
  • Ensure there is no live wire contact
  • Have proper insulation to live parts, enclose them properly with high-quality branded wiring, and ways to break/stop any surge
  • Direct contact is when we can come in contact with a live wire accidentally or through a current leakage
  • To protect against injury for these reasons, features of the protection system in any electrical installation must be in place

No compromise on the quality of cables or wires

  • The cable must be made out of copper and complies with IS 8130 for insulation
  • Aluminum wires are a strict no
  • Know the distinction between Single-Core and Multi-Core wires, and use them appropriately
 Single Core Cable or Multicore - basics of electricals

Single-Core wire

Multicore - basics of electricals

Multi-Core wires


  • Single-core strands are normally used for house wiring. These are not having the extra black cover. We must make sure the PVC insulation of these is fire retardant and has a low smoke
  • Multi-core wires are used for connecting an appliance with the plug. They are having the extra sheathing (black cover) which makes it safe
  • Normally, light/fan circuits are wired with a 1.5 sq. mm cable. Plus, power plugs are wired with a 6/16A with 4 sq. mm. cable
  • The builder should have followed the color code: RED, BLUE, YELLOW for phase, BLACK for neutral, and GREEN for earth wire. This helps avoid any unsafe issues when a repair or modification is needed

Switch and Socket

  • Switch or Socket needs to be high quality and able to withstand constantly being switched ‘on’ and ‘off’
  • High quality branded switches would ensure that they do not fail decades after they are used
  • A poor quality switch and socket eventually weakens resulting in heating and insulation failure
  • The sockets and switches in India are usually made as per Indian Standards, however, high grade and quality switches are usually more expensive than low ones
  • Quality shows in workmanship, and the earth pin needs to be thick and long to avoid any shock to the person touching the appliance
  • Sockets with a shutter ensure that kid do not accidentally put their fingers inside it

12 M Box- basics of electricals


  • A Steel or GI Electrical box of good quality must be bought
  • Using Steel/GI Box results in earthing and tripping of MCB


SCHLEMMER Make PE Grade Flexible Conduit Pipes- basics of electricals


  • Wires must not be laid open. Concealed wiring is normally provided by most builders and that’s safe!
  • Rigid pipe or metallic pipe must be used by the builder for laying wires in the open
  • With concealed wiring, mechanical damage does not occur, plus smoke does not spread because there is no oxygen available to cause its spread
  • Concealed wiring is more aesthetic
  • One should for a conduit (flexible or non-flexible) that is in accordance with Indian Standards

Knowledge and safety go hand in hand. One must not take the knowledge about electrical devices easy!
