Electrical Wires — Frequently Asked Questions
Choosing the right wire and cable for home and construction wiring
Wire size (sq mm) refers to the cross-sectional area of the copper conductor and determines current-carrying capacity. 1.5 sq mm is used for lighting circuits (up to 10A). 2.5 sq mm handles power points and fans (up to 16A). 4 sq mm is for high-load appliances like geysers and ACs (up to 25A). Always match wire size to the circuit's load.
We stock wires from trusted brands including Polycab, Finolex, Havells, and RR Kabel — all ISI marked and BIS certified. These are the most widely used brands by electricians and contractors across Delhi NCR. All are available in standard coil lengths of 90m and 180m.
FRLS (Flame Retardant Low Smoke) wire is designed to resist fire spread and emit minimal toxic smoke when burning. It is highly recommended for residential buildings, hospitals, hotels, and any space where fire safety is critical. For new construction or renovation in Delhi NCR, FRLS wiring is strongly advisable.
As a rough estimate, a standard 2BHK apartment typically requires 250–350 metres of wiring across all circuits. Measure the distance from your distribution board to each switch/socket point, add 20% for loops and joints. For accuracy, get an electrician to prepare a point-wise wiring schedule before ordering.
