Whenever we need to need how many amps a wire can handle, we turn to the NEC 310.16 table. The 310.16 table is basically anampacity chart; it tells us what is the ampacity of copper and aluminum wires. The full name for this table is“Table 310.16 Ampacities of Insulated Conductors with...
Aluminum is two–three times less expensive and three orders of magnitude more abundant in Earth crust than copper. Having 61% of copper conductivity but 30% of its specific weight, aluminum conductor is about 50% lighter than copper with the equivalent electrical resistance. It is, therefore, ...
