5 Types of Electrical Wiring For House And General Rules


An electrical wiring system is the process of connecting cables and wires to connected equipment such as fuses, switches, sockets, lights, fans, other electrical equipment, etc. To the main distribution board, which is a particular structure attached to the utility pole to ensure an uninterrupted power supply. 

When installing electrical wires and cables, it is essential to take extra care. Check out the general rules and types of electrical wirings for a house

Have a look at types of electrical wiring and general rules

General Rules For Electrical Wiring

  1. A two-pole linked main switch and a fuse unit must be installed near the point of entrance of supply cables on every installation. If one pole in a two-wire arrangement is permanently earthed, no fuse, switch, or circuit breaker should be installed on that pole. In a three-phase supply, a three-pole switch and fuse unit should be used.
  2. The conductor used must be of significant length to safely carry load current.
  3. The conductors installed must be safe in every way.
  4. A distribution fuse board must be attached to each sub-circuit.
  5. Each line (phase or positive) must be protected by a fuse with the appropriate rating, according to the requirement.
  6. In earthed conductors, no fuse or switch is required.
  7. A separate means of isolation, such as a switch, must be provided for each circuit or equipment.
  8. All gear that requires attention must be equipped with a means of access.
  9. Light and fan wiring, as well as power wiring, must be kept separate in any building.
  10. The bottom of a switchboard should be 1 to 25 meters above the ground level.
  11. All plugs and socket-outlets must be of the 3-pin type, with the corresponding pin of the socket permanently attached to the earthing system.
  12. Lamp holders in bathrooms must be made of insulating materials and equipped with a protective shield, and the earth continuity conductor must not be less than 7/0.915 mm in diameter.
  13. All metal sheaths or conduits for any wiring, as well as the metal covers of all-consuming devices or appliances, must be adequately earthed to prevent electrical shock from leakage or insulation failure.
  14. Each sub-circuit must be safeguarded by a fuse or automatic circuit breaker against excessive current (which can arise due to overload or insulation failure). To avoid risk, all live conductors must be insulated or otherwise protected.
  15. Before turning on the power, the installation must be thoroughly inspected.

Electrical Wiring Systems when taking Connection to Home Joint Box

1. Connections to appliances are created using joints in this wiring style. Joint boxes with appropriate connections or joint cutouts are used to create these joints. This style of wiring does not necessitate a large number of cables.

2. Looping System: This wiring approach is widely utilized in the industry. Lamps and other appliances are linked in parallel so that they can all be regulated separately. The feed conductor is looped in by bringing it directly to the terminal and then carrying it forward to the next point to be fed when a connection is required at a light or switch.

A mortar made from gypsum plaster with certain impurities present or added during the calcining process, sand or wood fibre, and water for plastering interior surfaces.   Know how to find the cement plastering ratio and calculating the cement and sand quantities needed for plastering. Here is the complete guide The house’s interior and exterior walls are both plastered with cement plaster. To do a good job, you’ll need the best cement plastering available. Water, fine aggregates, and Portland cement are mixed to make cement plaster. To make cement plaster, different amounts of cement and sand are combined. There are three different types of cement grades to pick from. In the market, there is Ordinary Portland Cement (OPC), Portland Slag Cement (PSC), and Portland Pozzolana Cement (PPC). There are two grades of OPC: 43 and 53. Plastering work is best done with both grades. This is the crucial distinction. Exteriors are normally coated with cement render, while interiors are usually com
