recommended wire gauge

Best answer


To get the best energy transfer a thicker wire such as a12-gaugewire would be preferred over an 18-gauge thinner wire. Cable Length and Distance Your decision should also be based on the length of the cable run and the impedance,or power requirements of your speakers.

  • How many gauges of wire are there?

  • According to the American Wire Gauge (AWG) method, the highest Gauge of a wire is Nr. 36 AWG, and the smallest Gauge is Nr. 0000. The diameters of these two are 0.005 inches and 0.46 inches, respectively. There are 40 gauges between these largest and smallest sizes, or you can say 39 steps.

  • What is the highest gauge wire?

  • According to the American Wire Gauge (AWG) method, the highest Gauge of a wire is Nr. 36 AWG, and the smallest Gauge is Nr. 0000. The diameters of these two are 0.005 inches and 0.46 inches, respectively.

  • How do I know what size AWG wire I Need?

  • To adequately figure out what size AWG wire you need, you require at least a wire gauge chart. AWG gauge wires have specified diameter, cross-section, and ampacity (how many amps they can handle). Here鈥檚 the thing: AWG is a logarithmic stepped standardized wire gauge system used since 1857. To put it mildly, it鈥檚 rather complex.

  • What gauge wire should I use for 30 amps?

  • For 30 amps, the 12 gauge wire (with 35 amp rated ampacity) is a better choice. For the 20 amp circuit, on the other hand, the 12 gauge wire would be an optimal choice. 10 gauge wire is rather cheap per foot. iGreely, for example, offers 8 gauge wires for $1 to $5 per foot (longer 10 gauge wires are cheaper per foot):
