Example: Three 1.5 mm² PVC circuits in one conduit → multiply base 15A (method B2) by = 10.5 A .
For XLPE (90°C conductor):
| Installation Method | Ampacity (Amps) | |---------------------|------------------| | A1 – In insulated wall conduit | | | B2 – In conduit on wall | 18 A | | C – Clipped direct | 21 A | | F – Free air | 24 A | iec 60364 current carrying capacity 1.5 mm2 copper
This paper provides an in-depth analysis of the current carrying capacity of 1.5 mm² copper conductors in electrical installations, as specified in the International Electrotechnical Commission (IEC) standard 60364. The study aims to determine the maximum current that can be safely carried by 1.5 mm² copper conductors under various installation conditions. Example: Three 1
Rated for 90°C . Because XLPE can handle more heat, a 1.5 mm² XLPE cable can often carry 3–5 Amps more than its PVC counterpart under the same conditions. 4. Voltage Drop Considerations Rated for 90°C
