Copper Vs Aluminum Wire Size Chart

Copper Vs Aluminum Wire Size Chart - If aluminum is used in an application where copper was previously used, it is typically sufficient to use an aluminum conductor two awg sizes larger than that of copper. To be on the safe side we use awg #10 (the smallest one) in the figure above and estimates the maximum current to be approximately 30 amps. 250 kcmil, 300 kcmil, 350 kcmil, 400 kcmil, 500 kcmil, 600 kcmil, 700 kcmil, 750 kcmil, 800 kcmil, 900 kcmil, 1000 kcmil, 1250 kcmil, 1500 kcmil, 1750 kcmil, and 2000 kcmil. Aluminum wiring could break or corrode over a few decades. Web 830 south west street / sikeston, mo 63801. For 60 amps at 220v, an amateur will utilize wire size 6.

This Figure Should Be The Peak Current So That The Cable Can Be Sized For The Worst Case.

Aluminum wiring could break or corrode over a few decades. Awg means american wire gauge, and the normal wire size in the us is 6 awg or 4 awg for 220v electricity. As a rule of thumb, using aluminum conductors two american wire gage sizes larger than copper are typically sufficient for replacement. 75°c (167°f) thw, thwn, se, use, xhhw:

It Is Important To Consider Factors Like Conductivity, Cost, Installation, Durability, And Compatibility When Deciding Which Type Of Wire To Use.

These are considered bigger wires (thicker) and can have up to 560a ampacities. Wire size and amp r atings wire gauge size copper aluminum. Web select the wire conductor material, either copper or aluminum. Maximum current diagram based on wire size in metric units mm 2:
