What Is a Junction Box
A junction box allows you to have outlets, switches, and other electrical hookups throughout your home. These boxes are the reason electricians can splice wires and connect fixtures to devices. Because of this, you can find one in almost any building across the country.
Typically, there’s at least one junction box in each home. Depending on the number of floors you have and your wiring setup, you may have a second box that controls another floor.
How do you identify the junction box? Look for a box made from sturdy materials, such as a hard plastic enclosure.
These materials keep the box safe from external threats and electrical malfunctions. Another helpful feature is that you can lock them, keeping them safe from potential vandalism.
Why You Need Junction Boxes
Junction boxes hold your various spliced wires in a single system. In doing so, it allows you to have several electrical components in a room. Instead of having long wires that run from an electrical panel throughout the house, you can connect wires to the breaker.

There are several types of junction boxes, but only a few are common to most environments. The most prominent kind is the standard residential box.
Manufacturers create standard residential boxes specifically for home use. Their materials suit them for indoor locations, with plastic enclosures in square, rectangular, and circular shapes.
They have more space than average junction boxes to hold more wiring. A 4-Inch square box is another option well-suited for indoor locations. These boxes measure between 1.5 inches and 2.8 inches, allowing enough space for basic wiring.
These boxes help electricians who need to lay wire in different directions. One of their advantages is that you can place them anywhere in a room.
Another common type of junction box is the outdoor type. These systems protect their interior wiring from several weather conditions, ranging from rain to excessive heat. In doing so, they protect your wiring from damage caused by outdoor elements.
