current rating wire gauge
People also ask
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.
