Cable cross-section for an LED strip
Load, voltage and cable length — we will work out the cross-section that keeps the voltage drop within limits and the cable cool.
Total power of the strip this cable feeds
Supply to strip, one way
For LED strip 3%, at most 5%
Cross-section needed

The cross-section is rounded up to a standard size and checked against the permitted current (IEC 60364-5-52).
