Wire Ampacity Size Table * Small Conductors. Unless specifically permitted in 240.4(E) through (G), the overcurrent protection shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG copper; or 15 amperes for 12 AWG and 25 amperes for 10 AWG aluminum and copper-clad aluminum after any correction factors for. Wire Size & Amp Ratings Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or "amps." You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating. These Tables of Electrical Service Entry Cable Sizes, Electrical Circuit Wire Diameters, Circuit Ampacity, Allowable Voltage Drop, & Wire Size Increase based on Run Length assist in determining the electrical service size or other required electrical wire sizes at buildings. AWG: In the American Wire Gauge (AWG) system, wire size diameters can be calculated by applying the formula D (AWG)=.005·92 ( (36-AWG)/39) inch. For the 00, 000, 0000 etc. gauges you use -1, -2, -3, which makes more sense mathematically than "double nought."

American wire gauge (AWG) is a standardized wire gauge system for the diameters of round, solid, nonferrous, electrically conducting wire. The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0). What Is The Use Of Cable Size Calculator? Cable (or conductor) estimating is the way toward choosing suitable sizes for electrical power cable conductors.
The cable size and length of a cable line mainly determine the voltage drop of a circuit. The smaller the cable size or, the longer the cable length required for your circuit, the greater the voltage loss. If you find that the voltage drop of the circuit has exceeded the 4% stated, you would need to upsize your cable. 4. Table 12E, referenced by Rules 4-006 and 12-406 and Tables 5D, 12B and 12C, provides a lookup of allowable ampacities for Type DLO cables in a permanent installation in cable-tray. Table 13 , referenced by Rules 14-104 and 28-204 , provides the rating or setting of overcurrent devices protecting conductors for general use where not otherwise specifically provided for and based on the ampacity.

Cable Sizing Calculation Steps. The process of the size calculation method consists of six steps. Collect data about cable, load, and environmental conditions. Determine the minimum cable size for continuous current carrying capacity.; Determine the minimum size of the cable based on voltage drop.; Determine the minimum size of cable for short circuit conditions. NEC Wire Size Table 310.15 (B) (16) (formerly Table 310.16) & Chart Factors Affecting the Wire Size Current Carrying Capacity: The amount of current the wire needs to carry influences its size, ensuring it can handle the load without overheating.
