2.5mm2 cable can carry different Amp electric current in different situations. Different situations include different temerature and different working environment. Below article will introduce this knowledge to all people with this confusion.

Can I use 2.5mm2 cable for 32amp

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.

Bare wire cable 2.5mm without PVC sheath will carry about 30 Amp electric current.

So, 2.5mm2 electric wire can’t carry 32 Amp electric current. When use it for house wiring decoration, it is recommended to carry 16 Amp to achieve the long time safety use.
