The correct answer is based on the understanding of angle pull requirements in electrical installations, particularly concerning the size of the wire used. When determining the appropriate American Wire Gauge (AWG) for cables subjected to angle pulls near junction boxes, it is critical to select a wire size that can effectively handle the mechanical stresses and electrical load without compromising safety or performance.

Choosing a wire size of AWG 4 or larger ensures that the cable has sufficient mechanical strength and can accommodate the angle pull forces that occur when a cable needs to bend at sharp angles. This is particularly important in installations where the cable must navigate turns or is subject to potential friction and supports within the junction box. Smaller wire sizes, like AWG 5 or below, may not perform adequately under these conditions, leading to potential damage or failure of the installation.

Furthermore, using an appropriately sized cable reduces the risk of overheating and ensures that the electrical continuity is maintained, providing a safe and reliable electrical system in accordance with established codes and standards. Therefore, a minimum cable size of AWG 4 meets the necessary specifications for angle pull requirements, delivering both durability and electrical integrity.
