The answer to 'which is better junction box or' is that junction boxes are generally better than electrical outlets for most electrical wiring and installation projects in homes. Junction boxes provide a secure, code-compliant way to connect and protect electrical wires, while outlets are primarily used for plugging in electrical devices and appliances.
Junction boxes offer several key benefits over outlets. They are more durable, fire-resistant, and tamper-resistant, helping to prevent electrical shocks and fires. Junction boxes also make it easier to add, remove, or modify wiring in the future, as the wires are contained and accessible within the box. Additionally, junction boxes are required by electrical codes in most areas for any electrical connections that are not inside a wall or other enclosed space.
