The ampacity of each conductor size in the dropdown menu below is based on nec 2005 table 31016 for 60c insulated conductors rated 0 through 2000 volts with not more than three current carrying conductors in raceway, cable or earth with an ambient of 30c (86f.
Doncaster cables is the largest british owned general wiring manufacturer in the uk we have been manufacturing cables since 1984 and among our current staff alone we have over 1000 years direct cable manufacturing experience. 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. Cable tray manual based on the 2014 national electrical code®† cable tray manual 2014 cable tray manual b-line series cable tray systems man-1 eaton ®† mark shown is the property of its respective owner. Wire gauge refers the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter.
1-800-945-5542 priority wire & cable, little rock, ar pwc-2018 triplex aluminum conductor 600v urd the above data is nominal and subject to manufacturing tolerances. No reduction can be applied to any portion of a 3 wire circuit consisting of 2 ungrounded (hot) conductors and the neutral conductor derived from a 4 wire wye connected system lastly, no reduction is permitted to portions of the system supplying nonlinear loads. Conductor types building wire conductor types aluminum building wire aluminum building wire is typically made of aa-8000 series table 31015(b)(6) conductor types and sizes for table 31015(b)(6) conductor types and sizes for 120/240-volt. The american wire gauge article contains a table showing allowable ampacities for a variety of copper wire sizes conductor ampacity [ edit ] the ampacity of a conductor, that is, the amount of current it can carry, is related to its electrical resistance: a lower-resistance conductor can carry a larger value of current. Along with the cable sizing calculation results, this section also displays the required cable sized, cable ampacity, percent of voltage drop, and percent of starting voltage if cable sizing options for the corresponding requirements are checked.
Electrical cable sizing software current capacity to bs 7671, era 69-30 and iec 60502 impedance and voltage drop to iec 60909 and cenelec clc/tr 50480 cloud based - any device, anywhere. American wire gauge (awg), also known as the brown & sharpe wire gauge, is a logarithmic stepped standardized wire gauge system used since 1857 predominantly in north america for the diameters of round, solid, nonferrous, electrically conducting wire. Learn all about conductor size this is one of our series of articles delving into the components and concepts used when engineering custom cable allied wire & cable is a custom cable manufacturer, offering custom-made cable solutions for challenging applications where stock cable just won't do. For one conductor (wire or cable), a circular mil represents a smaller unit of area than the square mil definition: a wire in its usual form is a single slender rod or filament of drawn metal. Rules for sizing branch-circuit conductors and overcurrent protection by gerald newton october 29, 1999 there are many rules in the 1999 national electrical code for calculating loads, determining the correct size conductors, and determining the correct overcurrent protection.
If specs on an appliance plate read 15 amps, 115 volts the distance from the power source to the receptacle (plug) where the appliance is going to be plugged is 230 feet, what is the wire (american wire gage) or conductor size, the thickness of the wire. 1 nema junction box sizing, conductor bending radii & fiber optic cable from: nec 2005 - article 31428, article 11074 & article 770 wsdot winter 2008. Conductor and cable sizing the purpose of conductor and cable sizing is to determine how best to transport a given current, determined by voltage, through an insulated conductive material.
Hopefully, this exercise of reviewing functions of bonding, grounding and neutral conductors and criteria for selecting appropriate sizes of these unique conductors will help to further clarify the subject of bonding and grounding. All cable sizes given on this page refer to single core ho7rnf rubber insulated cable, at an ambient temperature of 30 deg c, and a conductor temperature of 85 deg c max cable sizes should only be used as a guideline and if not using ho7rnf cable, all figures should be checked against the manufacturers data sheet. Cable designers guide how to specify cable insulated conductors specify quantity, gauge, stranding and insulation type for the conduc-tors allowance of 10% spares is a common practice. The load current rating and the overcurrent protection for conductor types shall not exceed 15 amperes for 14 awg, 20 amperes for 12 awg, and 30 amperes for 10 awg aluminum and copper-clad aluminum after any correction factors for ambient temperature and number of conductors have been applied.
