People also ask

  • Which is better aluminum or copper?

  • the conductivity of copper is stronger, pound for pound aluminium proves to be almost double as effective a conductor. Aluminium is more flexible than copper making it easier to wind in production processes. The higher resistivity of aluminium gives inherently lower eddy losses in the windings. This mitigates the risk for hot spots.

  • What size is 4 0 aluminum wire?

  • As per code the aluminum conductor size for a 200 amp service entrance is 4/0 awg. Recently the code has stated that the size size must be 250 awg unless a demand load calculation can be completed to prove to the local inspection authority that the 4/0 conductor size does not exceed 185 amps of draw. 4/0 awg is actually rated for a maximum of 185 amps but can be used due to its ease of installation.

  • Can you mix copper and aluminum?

  • Copper and aluminum can be combined to form a copper-aluminum alloy. However, under very high temperature, copper and aluminum can form a solid solution. When this solution cools, the intermetallic compound CuAl2, or copper aluminide, can form as a precipitate.

  • How do you calculate electrical wire size?

  • ρ = Specific resistance or resistivity of ConductorD = Distance in Feet (One way) i.e. the total circuit lengthI = Load Current
