Drywall, also known as plasterboard, is a popular choice for interior walls due to its versatility, affordability, and ease of installation. However, when it comes to electrical installations, it is crucial to follow the proper guidelines to ensure safety and compliance with local building codes. One of the primary concerns is whether junction boxes can be placed behind drywall.
Understanding Junction Boxes
Junction boxes are electrical enclosures used to house and protect electrical connections. They are typically used in residential and commercial settings to connect wires, outlets, switches, and other electrical components. Junction boxes are available in various sizes and types, and they must be properly grounded and insulated to prevent electrical hazards.
Can Junction Boxes Be Behind Drywall?
Yes, junction boxes can be installed behind drywall, but there are specific requirements and considerations to keep in mind.

According to the NEC, junction boxes must be installed in accordance with the following requirements:
1. The box must be securely fastened to the stud or framing member.
2. The box must be accessible for maintenance and repair.
3. The box must be adequately insulated to prevent the spread of fire.
4. The box must be properly grounded.
