What Are The Properties Of #12 Awg Thhn
What Are The Properties Of #12 Awg Thhn. For #12 thhn the ampacity is 25a at 75c. This bare copper building wire has a voltage rating of 600v and a maximum temperature of 90°c.
0.380 mm / 0.015 inches; Listed by ul as gasoline and oil resistant 11. The wire diameter is sufficient, and the abrasion coefficient is significantly reduced when threading the tube.
Comprised Of A Single 12 Gauge Solid Bare Copper Conductor With Thermoplastic High Heat Resistant Pvc Insulation With A Nylon Jacket.
It limits the number of amps the wire can safely carry. The higher the number the lower the amps. The awg standard includes copper, aluminum and other wire materials.
This Wire Features A 12 Awg Stranded Bare Copper Conductor, Pvc Insulation, And A Nylon Jacket.
It means a higher awg value would mean a smaller size. The gauge is related to the diameter of the wire. 12 awg # of conductors:
In Other Circumstances, You Might Be Permitted To Protect The #12 With A 25A Or Even Higher Rated Breaker (Especially For Motor Circuits) But The Ampacity Remains 25A With 75C Temperature Limits.
Annealed soft copper per astm b3 and astm b8. For #12 thhn the ampacity is 25a at 75c. The different letters in thhn wire denote particular properties of the cable:
Make Sure This Fits By Entering Your Model Number.
The higher the gauge number, the smaller the diameter and the thinner the wire. General purpose ul 83 building wire. To quickly summarize the chart, the 0000 awg has the largest diameter.

Common gauges you might see are number 8 rated for 40 amps, 12 rated for 20 amps 18 (common for light fixtures) rated for 10 amps. Awg/kcmil inches mm inches mm inches mm lbs/kft amps. One reason for the 20 amp limitation for #12 copper is that binding screw terminals have more than their fair share of contact resistance.
