• A. No. 4-40
• B. No. 6-32
• C. No. 8-32
• D. No. 10-32

Answer: (B)

The size of screws typically required to fasten a plug receptacle to an electrical box is No. 6-32. This size is standardized for mounting receptacles in residential and commercial electrical installations, providing adequate strength and compatibility with most electrical boxes and receptacles. The No. 6 screw has a sufficient diameter and threading design to ensure a secure attachment while still being manageable to install and remove when needed. Using the correct screw size is crucial not only for ensuring the receptacle is firmly mounted but also for maintaining safety and functionality. Correctly sized screws help in preventing damage to the receptacle or the box itself and allow for proper alignment with the mounting holes. Additionally, understanding which screws are suitable fosters proper installation practices, an essential aspect of electrical contracting work in California and beyond.
