How many cables are permitted to enter a cutout box per connector?

One
Two
Three
Four

The correct answer is: Two

The correct answer indicates that a maximum of two cables is permitted to enter a cutout box per connector. This guideline is based on electrical code requirements which are intended to ensure safety, prevent overcrowding, and maintain the integrity of electrical connections. Having two cables allows for adequate space for proper termination without risking damage to the insulation of the wires or creating a potential for overheating due to restricted airflow. Additionally, managing the number of cables per connector helps in organizing the wiring, reducing the likelihood of errors during installation or maintenance. While it can be tempting to bring in more cables to a single connection point for efficiency, this practice can lead to complications, including increased heat generation and difficulties in troubleshooting. The code is designed to enforce standards that promote safety and ease of use, thus restricting the number of cables to two per connector is a measure to facilitate these goals.
