  • What is the AWG rating of electrical wire?

  • Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. Be aware that the current load depends on installation method 鈥?the enclosure 鈥?and how well the resistance heat is removed from the cable.

  • What do the gauge numbers mean on electrical wire?

  • 1)Current ratings for up to 1000 V, PVC-insulated single and multicore wiring cables, ambient temperature up to 30oC The higher the gauge number, the smaller the diameter, and the thinner the wire.

  • What is the relationship between gauge and current?

  • The higher the gauge number, the smaller the diameter, and the thinner the wire. Because of less electrical resistance a thicker wire carries more current with less voltage drop than a thinner wire. For longer distances it may be necessary to increase wire diameter – reducing the gauge – to limit voltage drop.
