What is the main purpose of a junction box in electrical installations?

The main purpose of a junction box in electrical installations is to house electrical connections and protect them. Junction boxes provide a safe and organized way to manage and safeguard the electrical connections between wires. They prevent accidental contact with live wires, reducing the risk of electrical shocks and shorts. Additionally, junction boxes keep electrical connections insulated from moisture and other environmental factors that could cause damage or malfunction.

By providing this protective housing, junction boxes facilitate safe repairs, upgrades, or changes to wiring configurations while ensuring compliance with electrical codes and standards. This crucial function makes them an essential component in the installation and maintenance of electrical systems.
