Issue:Volatile cost of copper metalHeavy material to transport and install
Solution:Research another form of electrical wiring, such as aluminum
Electrical DepthElectrical DepthCopper vs Aluminum Wire Copper vs Aluminum Wire
AnalysisAnalysisCopper Characteristics:Higher electrical conductivityAmpacity is 1.6 times that of aluminumHarder and stronger material which can stand much more abuse over time and installationCan withstand tighter twists, harder pulls, and more bends at junction and termination boxes without stretching or breaking
Aluminum Characteristics:Softer material, lower modulus of elasticityNeed more critical installation procedures in order to secure bad connectionsThermal expansion coefficient is much larger than copperAluminum alloys are more active metals that make them more susceptible to corrode around moisture causing a shorter life span.
Recommendation: Recommendation: Continue installing copper wire for building electrical Continue installing copper wire for building electrical distribution systems.distribution systems.
