![]() If that wasn’t the case, everyone would purchase 0AWG for every application to eliminate overheating concerns. Thicker wires are more expensive than their thinner counterparts. However, the price of the cable concerns them. But if the thickest conductors are the safest options, why do people use 14AWG instead of 12AWG?ġ2AWG is the best option.
