Fake and under-specified wire is a real problem in the Indian market. It looks the same in the shop, and the difference only shows once it is in the wall. A minute spent reading the box helps.
What the box should tell you
- The ISI mark with the standard number, IS 694 for PVC house wire, and the manufacturer’s BIS licence number (CM/L).
- The conductor size in sq mm and the coil length in metres.
- The voltage grade, 1100 V for house wire.
- The insulation grade, such as HRFR, FR-LSH or HFFR.
- The manufacturer’s name and address, and a customer care number.
Three quick checks
- Verify the licence. Enter the CM/L number in the BIS Care app to confirm the licence is valid and belongs to the brand on the box.
- Look at the copper. Strip a short length. Good copper is bright and uniform, with fine strands that are not brittle.
- Check the length. A 90 m coil should be 90 m. Short coils are a common way to cut corners.
