Conductor sizes indicated are based on copper <br />unless specifically indicated as aluminum. Conductors designated with the abbreviation "AL"indicate <br />aluminum. <br />2.Copper Conductors: Soft drawn annealed,98 percent conductivity,uncoated copper conductors. <br />3.Aluminum Conductors (only where specifically indicated or permitted for substitution): AA-8000 <br />series aluminum alloy conductors. <br />H Minimum Conductor Size:12 AWG. <br />I Maximum Conductor Size:500 kcmil <br />J Conductors for branch circuits shall be sized to prevent a voltage drop exceeding three percent (3%)at the <br />farthest outlet of power,heating and lighting loads,or any combination of such loads. The maximum total <br />voltage drop on both feeders and branch circuits to the farthest outlet shall not exceed five percent (5%). <br />1.Where the conductor length from the panel to the first outlet on a 120 volt circuit exceeds 50 feet,the <br />branch circuit conductors from the panel to the first outlet shall not be smaller than #10 AWG. <br /> Increase the branch circuit conductor size an additional wire size for reach 100’of additional length of <br />the entire circuit. The ground conductor size shall be increased proportionately to the increase in the <br />phase conductors per 2020 NEC 250.122(B). <br />K Conductor Color Coding: <br />1.Color code conductors as indicated unless otherwise required by the authority having jurisdiction. <br /> Maintain consistent color coding throughout project. <br />2.Color Coding Method: <br />a.Conductors #10 AWG and smaller shall be factory color coded. <br />b.Conductors #3 and larger shall be factory color coded on the entire length. <br />3.Color Code: <br />a.480Y/277 V,3 Phase,4 Wire System: <br />1)Phase A: Brown. <br />2)Phase B: Orange. <br />3)Phase C: Yellow. <br />4)Neutral/Grounded: Gray. <br />b.208Y/120 V,3 Phase,4 Wire System: <br />1)Phase A: Black. <br />2)Phase B: Red. <br />3)Phase C: Blue. <br />4)Neutral/Grounded: White. <br />c.Equipment Ground,All Systems: Green. <br />d.0 -10V Dimming conductors:Violet and Grey <br />2.03 BUILDING WIRE <br />A Approved Manufacturers as listed below or approved equal: <br />1.Copper or Aluminum Building Wire: <br />Docusign Envelope ID: 2D852F9B-A7CF-462A-9536-444A53AA848A
