Angle pull dimensional requirements are applicable to junction boxes only when conductors are equal to or larger than what gauge?

The correct answer focuses on the specific dimensional requirements for angle pulls in junction boxes that are applicable when dealing with larger conductors. In this context, angle pull requirements become crucial for maintaining the integrity and safety of electrical installations. Conductors that are equal to or larger than 4 AWG typically require considerations for bends, pulling tension, and additional space to ensure that the conductors are not damaged during installation.

When you use conductors of this size, compliance with the dimensional standards helps facilitate smoother installation, less likelihood of insulation damage, and prevents excessive strain on the conductors that could lead to future reliability issues. Therefore, these angle pull requirements are notably important for electrical installations involving thicker conductors, and the threshold of 4 AWG represents a common standard that aligns with safety practices prescribed in the National Electrical Code (NEC).
