Frequently Asked Questions
What is a junction box used for?
A junction box encloses and protects spliced or connected wires, keeping the connection safe from damage and contained if a fault causes heat. Code requires splices to be inside an accessible box.
Can a junction box be hidden behind drywall?
No. Junction boxes must remain accessible, so they cannot be permanently covered by drywall or finishes. They are fitted with a removable cover plate that stays reachable.
What size junction box do I need?
Box size depends on the number and gauge of wires and connectors inside, per code box-fill rules. When unsure, choose a larger box for easier, safer wiring and follow local code.
