Electric current carrying capacity is different at different temperatures: The 2.5mm2 electric wire can carry 20 Amp electric current, when the temperature is about 20℃, and laying without any conduit. When it is high temperature, the 2.5mm2 wire can carry 18 Amp electric current.

Different laying methods will cause different electric current carrying: If laying without any conduit, it can carry about 20 Amp, but is laying with conduit, it can carry about 16 Amp. Different cable type will cause different electric current carrying: PVC sheath wire cable is different with bare wire cable.
