Finolex 4.0 sq mm price — every pack

Taxes extra as applicable. Larger quantities are priced better than the rates shown.

Reading the grades. Finolex Silver and Gold are both 90 m coils — Silver is the standard FR line and Gold sits above it. FR-LSH is flame retardant low smoke and halogen, which matters in flats, stairwells and any enclosed escape route, and costs a little more. FR and FR-LSH are also made in 180 m coils, and in a long coil that is 300 m for 1.0–2.5 sq mm and 200 m for 4.0 and 6.0 sq mm. Longer coils work out cheaper per metre and waste less at joints.

What 4.0 sq mm wire is used for

Finolex 4.0 sq mm is the size for air conditioners, larger geysers and heavy appliance circuits. In a normal house that means AC points, 3000W geysers, ovens. The matching protection is a 20A, Curve C breaker at the distribution board.

Every AC and large geyser should have its own dedicated 4.0 sq mm circuit.

Typical requirement: 1–2 coils in a 2BHK, 2–4 in a 3BHK, though the real number depends on your point count and the run length from the distribution board. Work out your own quantity with the wire quantity calculator, and confirm the size for each circuit with the wire size calculator — a long run can need the next size up purely because of voltage drop.

What you get at this price

100% genuine Finolex stock, verified by you before you pay. Every carton carries a QR on the outside and a second QR inside the box. Scan both at your own site: a genuine coil passes both, while a genuine carton refilled with duplicate wire passes only the outer scan. Anything that does not verify goes back on the vehicle and you pay nothing for it.

Why the price moves

A wire coil is mostly copper, and copper is an internationally traded commodity priced in dollars. Finolex revises its list periodically as copper and the rupee move, so the figures above are current to 21 May 2026 and will change again. That is also why no honest seller publishes a single fixed rate — the full explanation is in why wire prices keep changing.

Before you pay for any 4.0 sq mm coil

• Buy in your own name, not through a with-material contract — see how duplicate wire reaches your home.
• Insist on sealed cartons. Loose or cut wire carries no batch, no QR and no warranty route.
• Scan the outer QR on the carton and the inner QR inside the box. A refilled carton passes the first and fails the second.
• Check the printed markings along the insulation for even spacing and crisp characters.
• Take a GST invoice in your own name listing brand, size, grade and quantity.
