TABELA ZA PRETVORBO: IZ AWG/MCM V mm 2 CONVERSION TABLE: FROM AWG/MCM TO mm 2

AWG (American Wire Gauge) Razmerjemed AWG inmm 2 je povzeto po standardu STMB 258 - 02 (Standard Specification for Standard Nominal Diameters and Cross-Sectional Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors). MCM je okrajšava za 1000 Circular mil: 1 MCM = 1 kcmils. Circular mil je površinska enota, ki ustreza površini kroga s premerom 1 mil: 1 MCM = 1 kcmils = 0,5067 mm², torej je 2 kcmil ≈ 1 mm 2 Merska enota MCM se uporablja za vodnike z zelo velikim presekom; standardne dimenzije so: - od 250 do 400 z vmesnimi merami vsakih 50 kcmil - od 400 do 1000 z vmesnimi merami vsakih 100 kcmil - od 1000 do 2000 z vmesnimi merami vsakih 250 kcmil Pretvorni faktor med MCM in mm 2 je vzet iz NFPA 70, National Electrical Code (NEC) AWG (American Wire Gauge) Corrispondences between AWG and mm 2 come from STM B 258 – 02 standard; ASTM B 258 – 02 is the Standard Specification for Standard Nominal Diameters and Cross-Sectional Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors MCM is an abbreviation for thousands of Circular Mils: 1 MCM = 1 kcmils. Circular mil is a unit of area, equal to the area of a circle with a diameter of 1 mil: 1 MCM = 1 kcmils = 0.5067 mm², so 2 kcmil ≈ 1 mm 2 MCM is used for very large section wire, indeed standard sizes are: - from 250 to 400 in increments of 50 kcmil - 400 to 1000 in increments of 100 kcmil - from 1000 to 2000 in increments of 250 kcmil Corrispondences between MCM and mm 2 come from NFPA 70, National Electrical Code (NEC).
