90 m coils
Wire quantity calculator
Enter conductor metres, or start from a house sketch. Each line becomes 90 m Lifeline Plus S3 coils, rounded up. Several conductors can share one pipe, so this is not the conduit length.
Lifeline Plus coils
- 1.5 sq mm3 coils
- 2.5 sq mm2 coils
- 4 sq mm1 coil
- 6 sq mm1 coil
These figures are for planning. Cable size, the breaker and the final list have to be confirmed against the drawing, the load and the Havells datasheet.

Before you order coils
Why coils instead of loose metres?
Havells Lifeline Plus S3 is listed here as a 90 m coil. The page divides the metres by 90 and rounds up. A measured route can still change the count.
Where do the preset metres come from?
The 2 BHK and 3 BHK buttons use the middle of the allowance on the house wiring plan. They are not a measured bill of quantities.
