The electrical wires in the home are the lines that deliver power to all lights, fans, sockets, appliances, and machines. Good wiring will reduce your risk, keep your house efficient and prepare for long term use. Prior to doing any house wiring job, the homeowners should be familiar with the different types of electrical wires used in home construction. The proper electrical wire types take away risks of fire, loss of electricity, overheating and need for continuous repair. Here is a simple home wiring guide India on general home wiring and various types of wires that are used and their size.

Why Choosing the Right Electrical Wire Is Important

Safety

Safe house wiring begins at the proper high quality and size of wire.
Wrong wires can overheat, melt or give an electric shock.

Energy Efficiency

Good electrical wires make for less power loss.
They improve the performance of operating appliances and assist in maintaining regular power supply.

Long-Term Durability

High-quality house wiring materials will have longer useful life and will minimize breakdowns, loose connections and rewiring requirements.

Fire Protection

Fire resistant wires like FRLS wire and HFFR wire help reduce fire spread and limit smoke in fires.

10 Common Types of Electrical Wires Used in Homes

PVC Insulated Wire

PVC insulated wire is used in home electrical wiring.
It has a plastic coating that protects the conductor from damage and moisture.

FR (Flame Retardant) Wire

The FR-wire is fire-resistant.
In standard residence wired by builders, usually for basic fire protection.

FRLS (Flame Retardant Low Smoke) Wire

FRLS wire increases resistance to flame propagation and produces less smoke in fire.
It's good for apartments or closed rooms and safer indoor wiring.

HRFR (Heat Resistant Flame Retardant) Wire

HRFR wire is more heat resistant than regular FR wire.
Electricians use it when the temperature is higher or there is heavy load.

HFFR (Halogen Free Flame Retardant) Wire

HFFR wire will not emit toxic halogen gases when burned.
Safe for closed areas and new houses.

XLPE Insulated Wire

XLPE insulating wire has an advantage on heat resistance performance, insulation performance and durability.
It works well on higher load circuits.

Flexible Multi-Strand Wire

Multi-strand wire is flexible.
It's used by electricians in appliances, panels, and where a wire needs to move.

Single-Core Copper Wire

Single-core copper wire is a one conductor wire.
It can be used in lighting circuits, fan circuits, and socket circuits.

Multi-Core Electrical Cable

The form of multi-core electrical cable is more than one insulated conductor in an external sheath.
It's great for appliances, control wiring, and tight connections.

Armoured Electrical Cable

Armoured electrical cable has a protective metal layer.
They are the type of wires that electricians use for things that are underground, outside their electrical systems, and in heavier duty areas.

Electrical Wire Types and Their Applications

Lighting Circuits

Typically, for lighting installations, 1.0 sq mm or 1.5 sq mm copper wire is used, depending on the load and the electrician's design.

Power Sockets

The wires for power sockets must be thicker than the wires for lights.

Many home employ 2,5 sq mm cable for typical socket points.

Air Conditioners

Air conditioners require special wiring.

Electricians are likely to employ wires of 6 square millimeters or 4 square millimeters depending on the AC capacity and distance.

Kitchen Appliances

Safe wiring and proper earthing should be provided for kitchen appliances such as microwave ovens, chimneys, mixers etc.

Water Pumps

Water pumps require customer quality and long lasting electrical cable types suitable to the appropriate insulation and load capacity.

Outdoor Electrical Connections

Weather resistant cables are necessary for outdoor connections.

Armoured electrical cable is more suitable for situations where wires are exposed to soil, water or physical damage.

Electrical Wire Size Guide for Home Construction

1.0 sq mm Wire

Electricians use 1.0 sq mm wire where the load is light, like small lights.

1.5 sq mm Wire

In many houses 1.5 sq.mm wire is sufficient for lighting and fan circuits.

2.5 sq mm Wire

Regular power sockets and small appliances are compatible with wire 2.5 sq mm.

4 sq mm Wire

For places where bigger water-using appliances like geysers and smaller air conditioners run, you should use 4 sq mm wire.

6 sq mm Wire

Heavy loads, main lines, larger AC units, high-power appliances are with 6sq mm wire. Final electrical wire size for home is based on load, distance, voltage drop and local safety regulations.

Conclusion

When selecting the best electrical wire for house wiring, safety, load, room type, and budget are all considerations. The types of electrical wires are PVC insulated wire, FR wire, FRLS wire, HFFR wire, XLPE wire, flexible wire, copper wire, multi-core cable and armoured electrical cable. Homeowners ought to always pick certified wires and a licenced electrician for safe home electrical wiring.
