For angle pulls of conductors 4 AWG and larger, the minimum distance between raceway entries enclosing the same conductor must be at least ________ times the size of the larger raceway.

For angle pulls of conductors 4 AWG and larger, the minimum distance between raceway entries enclosing the same conductor must be at least ________ times the size of the larger raceway.

• A. 3
• B. 4
• C. 5
• D. 6

Answer: (B)

The correct answer is based on the National Electrical Code (NEC) guidelines, which stipulate that for angle pulls of conductors that are 4 AWG and larger, the minimum distance between raceway entries that enclose the same conductor must be at least four times the size of the larger raceway. This requirement ensures that there is adequate space for the conductors to bend without causing damage or undue stress on the cables. It also helps in the management of the conductors' thermal performance and prevents excessive strain on the terminations. In this context, the size of the raceway directly affects how the conductors are routed within the installation. Applying this fourfold distance rule facilitates proper spacing, allowing for smoother transitions which contribute to the longevity and reliability of the electrical system.
