How many watts and current can a 6-square copper/aluminum core wire load respectively?

Release time: 2023-10-25

according to the national electrical specification "500v copper core insulated wire long-term continuous load allowable current flow meter", the working temperature is 30 ℃, the current carrying capacity under long-term continuous 90% load, 6 mm² copper wire can pass 51A current for a long time, but considering factors such as pipe penetration, buried wall and ambient temperature, the maximum safe current carrying capacity is about 51*0.8 = 40A, then the maximum power that 6 square copper wires can withstand is 220*40=8800W.

Current conversion power

1A = 220W,10A = 2200W, and so on.

Copper core wire allows long-term current

6 mm² (32A ~ 40A)

Aluminum core wire allows long-term current

6 mm² (25A ~ 32A)
