Whenever we need to need how many amps a wire can handle, we turn to the NEC 310.16 table. The 310.16 table is basically an ampacity chart; it tells us what is the ampacity of copper and aluminum wires. The full name for this table is “Table 310.16 Ampacities of Insulated Conductors ...

NEC, THHN & AWG Wire Gauge Ampacity Rating Chart This section only serves as a guide when looking at a gauge chart. If you plan to install anything involving electricity, always call for a professional electrician to handle the work for you. The table below shows that the AWG value is opp...
Example:A 6 AWG aluminum wire has a rated ampacity of 50A. 80% NEC rule states that you can only load the wire up to 80% of the rated ampacity. That means that a 6 AWG aluminum wire can handle 40 amps of electrical current or less. ...

Max. Amp Load (Accounting For 80% NEC Rule) = 65A Ampacity × 0.8 = 52 Amps This is how many amps a 6 AWG copper wire at 75°C (167°F) can handle. Here is the complete amps table for 6 AWG wires for both copper and aluminum wires and all 3 temperatures: 6 Gauge Wire Amps ...
