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 wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).

The allowable values in the Ampacity Table are based on temperature alone and do not take voltage drop into consideration. **. Unless specifically permitted in Section 240.4(E) through (G), the overcurrent protection shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and.
This site offers many simple-to-use calculators and wire ampacity charts to aide you in properly sizing wire and conduit in compliance with the NEC. Visit the Calculators and Tables pages for a complete list of resources.
This table tells you what gauge wire (AWG or kcmil) you need to use for services and feeders ranging from 100 amps to 400 amps current. It gives us the AWG or kcmil number for copper and aluminum wires (same as copper-clad aluminum wires). We will look at the complete table further on. 310.12 (A) Services part.
INGNEC 2014 Article 110.14(C) Temperature Limitations. The temperature rating associated with the ampacity of a conductor shall be selected and coordinated so as not to exceed the lowest temperature r.
Local codes usually follow the NEC but can have variations for residential electric wiring. Always check with the building department of your municipality before doing electrical work. All lighting must be on either a 15-amp or 20-amp circuit.
