2910APPENDIX Ⅳ THE RELATIONSHIP BETWEEN DC 12VCABLE DIAMETER AND TRANSMISSION DISTANCEIt is the recommended max transmission distance when the cable diameter is fixed and the DC12V power consumption is lower than 10%. For the DC power supply devices, the max allowedvoltage loss rate is 10%. The cable listed in the table below is copper wire (the resistivity ofcopper is ρ=0.0175Ω*mm²/m).mmFeet(m)w0.8000 1.000 1.250 2.0005 122.13(37.23)190.83(58.16)298.17(90.88)763.31(232.66)10 61.06(18.61)95.41(29.08)149.08(45.44)381.66(116.33)15 40.71(12.41)63.61(19.39)99.39(30.29)254.44(77.55)20 30.53(9.31) 47.71(14.54)74.54(22.72)190.83(58.16)25 24.43(7.45) 38.17(11.63)59.63(18.18)152.66(46.53)30 20.35(6.20) 31.80(9.69) 49.69(15.15)127.22(38.78)35 17.45(5.32) 27.26(8.31) 42.60(12.98)109.04(33.24)40 15.27(4.65) 23.85(7.27) 37.27(11.36)95.41(29.08)45 13.57(4.14) 21.20(6.46) 33.13(10.10)84.81(28.85)50 12.21(3.72) 19.08(5.82) 29.82(9.09) 76.33(23.27)55 11.10(3.38) 17.35(5.29) 27.11(8.26) 69.39(21.15)60 10.18(3.10) 15.90(4.85) 24.85(7.57) 63.61(19.39)65 9.39(2.86) 14.68(4.47) 22.94(6.99) 58.72(17.90)70 8.72(2.66) 13.63(4.15) 21.30(6.49) 54.52(16.62)75 8.14(2.48) 12.72(3.88) 19.88(6.06) 50.89(15.51)80 7.63(2.33) 11.93(3.64) 18.64(5.68) 47.71(14.54)85 7.18(2.19) 11.23(3.42) 17.54(5.35) 44.90(13.69)90 6.78(2.07) 10.60(3.23) 16.56(5.05) 42.41(12.93)95 6.43(1.96) 10.04(3.06) 15.69(4.78) 40.17(12.25)100 6.11(1.86) 9.54(2.91) 14.91(4.54) 38.17
