Yes, in most cases, a junction box is required when connecting wires. It's not just a safety measure—it's also a code requirement in many regions, including under the National Electrical Code (NEC) in the U. 15, a junction box is required whenever: You cannot: Common Misunderstanding If a cable passes through without splicing or terminating, you may not need to install a junction box — but you must still protect the conductors according to the wiring method rules. A junction box must be. Choosing between a conduit body and a junction box depends largely on the purpose of the installation and the electrical code requirements. Here are some practical scenarios to help you decide: You need a directional change in a conduit run, such as a 90-degree turn or a T-branch. The wiring path. According to the NEC (National Electrical Code), all wire splices and electrical connections must be enclosed within an approved electrical junction box to ensure safety, accessibility, and code compliance. 1 (C) provides the designators for raceway trade sizes. In this article, we'll explain.
