4 awg amp rating You can consult the wire ampacity chart from the 1st Chapter and see that the most appropriate wire size for 80 amps is 4 AWG wire 4 AWG wire has a rated ampacity of 85 amps That is a perfect wire size for an 80 amp circuit If you want to have an even safer circuit you can use 3 AWG wire as the 80 amps wire size
Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating Cerrowire s ampacity chart helps calculate the load requirement for a circuit Amp ratings vs US AWG wire gauges The AWG American Wire Gauge is used as a standard method denoting wire diameter measuring the diameter of the conductor the bare wire with the insulation removed AWG is sometimes also known as Brown and Sharpe B S Wire Gauge

The following AWG American Wire Gauge table shows the AWG Size and diameter in millimeter mm and inches in in its cross sectional area in mm 2 Inche 2 and kcmil or MCM and resistance in ohms per 1000 feet and 1000 meter The AWG size chart also shows the current in amperes for chassis wiring and power transfer application AWG Wire size chart and ampacity table for design engineers including skin depth frequencies and tensile strength data electrical cable size
If you re buying wires by size in inches or millimeters or have stripped and measured uninsulated wires with a gauge tool you can also use a wire gauge chart to determine the maximum amperage of a wire Most charts provide ampacity for copper and aluminum wire and their most common insulation materials The Spruce Mira Norian Determine the allowable ampacities of insulated copper conductors single insulated copper conductors and more from the National Electrical Code Allowable Copper Conductor Ampacities tables

The Wire Ampacity Calculator will quickly calculate the maximum allowable current through a conductor based on wire size AWG or kcmil wire insulation conductor type and installation method Enter the information below to calculate the maximum allowable ampacity for current carrying conductors Calculate the maximum allowable wire ampacity for an insulated conductor given its gauge material temperature rating ambient temperature and conductor count
4 Gauge Wire VS Watt Does It Affect Amp The average 4AWG copper cable has an ampacity of 70A Considering 70A 12V gives 840W 120V gives 8400W 240V gives 16800W and 480V provides 33600W Understand wire amp ratings and how amps are defined with a useful ampacity chart
