291 Conductor Selection

CourseCode: SOC-291-420180
Length: 1 Hours

Target Audience
Intermediate Level

Conductor Selection 291 describes the different features of conductors and the considerations involved selecting conductors for electrical wiring applications. Electricians use the National Electrical Code(R) to guide the selection process. Different materials are used to construct conductors. Copper is the most popular choice due to its affordability, low resistance, and good conductivity. Insulation is used to protect conductors from damage and electricians from injury. Wire protection is added to conductors to prevent damage from environmental factors.Correction factors must be considered when selecting a conductor, including ambient temperature, number of conductors, and conductor length. When electricians use the NEC(R) and have an understanding of conductor features and correction factors, selecting appropriate conductors to safely carry power is ensured and essential when working with electrical systems.
