What is considered a criterion for the selection of electrical wire?

The selection of electrical wire is primarily influenced by specific criteria that ensure both safety and functionality in the intended application. Corrosion resistance is a crucial factor because electrical wires are often exposed to various environmental conditions, including humidity, temperature fluctuations, and corrosive elements. When wire materials resist corrosion, they maintain their conductivity over time and reduce the risk of failures or hazardous situations due to degraded wire integrity.

While cost considerations may also play a role in the selection process, they should not come at the expense of safety or reliability. Color preferences are generally irrelevant concerning performance and safety, as they relate more to visibility and identification. Brand reputation may provide some assurance of quality but does not directly reflect the wire's physical and electrical properties, such as its resistance to corrosion. Thus, corrosion resistance stands out as a vital criterion in ensuring that the electrical wire will perform effectively and safely in its operating environment.
