Which wire for which load
Common sizes for copper house wiring and what each point uses in this calculator. Your electrician may size up for long runs or heavier loads.
| Copper wire | Used for | Per point here | 90 m coil, FR |
|---|---|---|---|
| 1.5 sq.mm | Lights, fans, exhaust | 18 m | ₹1,530 |
| 2.5 sq.mm | 6A sockets, TV, chargers | 18 m | ₹2,430 |
| 4 sq.mm | 16A AC, geyser, kitchen power | 24 m | ₹3,780 |
| 6 sq.mm | Oven, EV charger, sub-mains | as designed | — |
| 10 sq.mm | Main line from meter to DB | as measured | ₹130/m cable |

Choosing wire, switches and protection
Wiring stays in the walls for decades. The wire insulation, the protection at the board and the earthing decide how safe the home is.
FR wire
Flame retardantGood for: budget homes and surface wiring.
Watch: gives more smoke in a fire than FRLS.
FRLS wire
Low smokeGood for: most new homes; less smoke and fumes if it burns.
Watch: buy ISI-marked copper from a known brand.
HFFR wire
Halogen freeGood for: premium homes, hospitals, offices where people must escape safely.
Watch: costs more; stiffer to pull.
RCCB, 30 mA
Shock protectionGood for: every home; trips on current leaking through a person.
Watch: test it monthly with its test button.
Use a licensed electrician. House wiring must follow the IS 732 code of practice and local electricity board rules; the supply company may ask for a test report before connection.
4Method
How the cost is worked out
Built up point by point, then the board and earthing are added.
- Wire coils. Single-core wire is sold in 90 m coils; lengths include phase, neutral and earth.
- Quality sets the wire type, switch plates, board and breakers.
- Location scales labour from village 0.85 to metro 1.28.
5Scope
What this calculator does and does not do
Knowing the limits helps you compare quotes fairly.
✓It does
- Count points room by room or from area
- List wire coils by size, conduit, switches and sockets
- Size the DB and count MCBs
- Add RCCB, earthing and main cable
- Price materials and labour
- Give a material list, CSV, shareable link and print
✕It does not
- Design circuits or check load and voltage drop
- Include light fittings, fans or appliances
- Cover inverter, solar, lift or three-phase panels
- Include meter, supply connection or deposit fees
- Know your local rates; change them to match quotes
6FAQ
Questions
What is an electrical point?
One outlet with its own wiring from the switchboard: a light, a fan, a 6A socket, or a 16A power socket for an AC, geyser, fridge or microwave. Contractors in India usually price house wiring per point.
How much does house wiring cost per point?
With concealed conduit, FRLS copper wire and standard modular switches, this calculator comes to roughly ₹1,150 for a light or fan point, ₹1,450 for a 6A socket and about ₹2,300 for a 16A power point, including labour, in a town. The distribution board, MCBs, RCCB and earthing are added separately.
Which wire size is used where?
Commonly 1.5 sq.mm for lights and fans, 2.5 sq.mm for 6A sockets, 4 sq.mm for 16A AC, geyser and kitchen power points, and 6 to 10 sq.mm for the main line from the meter. Your electrician may choose larger sizes for long runs or heavy loads.
How many points does a room need?
A bedroom usually has about 3 lights, 1 fan, 4 sockets and 1 AC point; a kitchen needs 3 or more power points for the fridge, microwave and other appliances. The calculator fills these in for each room and lets you change them.
Why do I need an RCCB and earthing?
An RCCB (residual current circuit breaker) of 30 mA cuts power in a fraction of a second when current leaks through a person or a faulty appliance. Earthing gives that leakage a safe path. Both are basic safety for any home.
Concealed or surface wiring?
Concealed conduit is laid in wall chases before plaster and is standard for new homes. Surface conduit is fixed on the wall; it is cheaper and quicker, and suits rewiring, shops and add-ons. The calculator lowers labour for surface wiring.
Does this include lights, fans and appliances?
No. It covers wiring, conduit, switches, sockets, the distribution board, protection and earthing. Light fittings, fans, ACs and geysers are bought separately.
Is my data stored?
No. The calculator runs in your browser and loads no third-party scripts. Inputs leave the page only if you copy the link, share on WhatsApp or download the list.
