![]() ![]() Which is better: a 12 or 16 gauge extension cord? Sizing of Wire According to Amp Wire SizeĪppliance, laundry, and bathroom circuits If you must pick between copper and aluminum, go with the former. At 167 degrees and 194 degrees F, 10AWG aluminum wire can transport 30A, according to the data provided by Atlantic Inspiration.ġ0 AWG copper wire, on the other hand, can transport 35 and 40 amps at 167 and 194 degrees F, respectively. ![]() A 10 AWG copper wire is superior to a 10 AWG aluminum wire in terms of current transmission. Copper conducts electricity more efficiently than aluminum. To put it another way, the circuit’s current is high enough to induce overheating in the thin wires but not high enough to trigger the breaker. The wires will overheat and melt if the wire size is less than the breaker size, and the breaker will not trip since it must detect more current than the little wire can carry. This is why the size of the wires must correspond to the size of the breaker. The breaker will trip if the cables are carrying more current than they can manage, preventing them from overheating. If you have a big breaker that can handle a lot of power, you’ll need a big wire to go with it. It does, however, carry less electricity than an 8-gauge cable. This is why having a gauge is so crucial.Ī 10-gauge wire may carry more power than a 12-gauge wire. The size of a wire determines how much current it may safely transport. Consumers are expected to utilize 10-gauge wire for 30 amps, regardless of whether the wire is copper or aluminum, according to NEC. ![]()
