Junction boxes are plastic or metal boxes that are used in houses or apartments for connecting wires. The connection within the box is known as a branch circuit and usually signifies the end of a cable run. A junction box needs the wire easy to access as all wires are connected in the building. You just have to remove the covering of the junction box for repairing or for additional wires to add. Junction boxes also prevent the wire from damage due to rain or any other environmental damage. This box also protected wires from illegal tampering.
Some of the basics of junction box wiring
Usually, a junction box in a house or a factory is used to connect single power to multiple outlets. For instance, a junction box may contain one wire power source that is connected to multiple power sources. They are generally made up of hard metal or plastic and usually sizes between two and a half to 3 ½ inches long.
The material of a junction box depends on whether your junction box is supposed to support any weight. Like metal junction boxes can support light fixtures on the other hand plastic junction boxes cannot support this weight. Another additional benefit of using a plastic junction box is that they can easily be installed than metal ones. However, a junction box is made to just cover wire splices be it metal or plastic.
Why must splices be in junction boxes?
All wire splices should be enclosed within a junction box in a house or a building to meet the electric code. But sometimes wire splices are missed and that causes fire hazards. Any wire, which is exposed to the environment, can be dangerous. Especially wire splices that are bared are prone to accidents because they can be tripped over, distort or expel sparks that can be hazardous for both children and pets. Junction boxes can be a good alternative to ignore a hazard. They are helpful for wire slices because they also allow the professionals to locate the wire splice area.
How to join the wire to the junction box?
The junction box is used to create all wire connections in the home called splice. The junction box is often attached to an electrical outlet. By making splices in a junction box the risk of electrical accidents occurring from connecting wires coming in contact with flammable articles diminishes considerably.
Once a new junction box is connected to the ceiling, other walls are ready to be connected to the wires.
Conclusion
We know that electricity and water are opposite to each other. It is important to cover all our main circuits with weatherproofing junction boxes to prevent electrical accidents. This junction box protects our electrical appliances from being damaged by lightning, electrical short circuit, fire, or any other natural calamity. Therefore, it is advised to cover your main circuit with a junction box.
