According to IEC 60364-5-52, the current-carrying capacity of 1.5 mm² copper conductors typically ranges from 13 A to 24 A, depending on installation methods, insulation (PVC or XLPE), and environmental factors. Actual capacity must be adjusted based on ambient temperature, cable grouping, and potential voltage drop.

Roughly 19.5A to 22A . This is the most efficient "standard" indoor method as the wall acts as a heat sink and there is better air exposure. 2. Key Derating Factors

The numbers above are "base" ratings. IEC 60364 requires you to apply that often lower the allowable current:

Per IEC 60364-5-52, the base value must be multiplied by correction factors.
