Junction Box and Cable Gland

A junction box contains a set of wire connectors or terminal blocks with an enclosure. Depending on the environmental conditions of where it will be placed,  the types of entry and exit points and the enclosure are typically composed of either plastic or metal. These considerations consist of the presence of dust or gas and the level of humidity.

The entry and exit points can be a more robust cable gland or a simple knock-out hole. This gland helps to avoid most external environmental conditions from getting inside the enclosure and causing problems to the connections. 

Junction box

Junction boxes can be explained as a metal or plastic enclosures used as housings for wiring connections. The connections inside the enclosure are called branch circuits and normally represent the end of a conduit run. If we need to extend the wires, then we are required for a junction box. It can remain accessible. We should have two choices; if we don't need re-run longer cables, we can splice in some additional cable

It can be designed as per the requirement. Metal and other material box fill of the junction box are based on the box size in cubic inches and the required space for each conductor size. Normally the junction boxes are placing outside walls of the buildings for easy access.

Secure the Cables

The security of the cable is important. By using cable glands, this job can perform well. The outer jacket of the cable should extend one-half to one inch beyond the clamp, and the cable wires should extend about six inches into the box. If necessary, cut the cables as required and by using wire strippers strip a three-quarter inch of insulation from each cable.

Cable glands will help to protect the end of the electric cables and the devices which are connected to the cables. cable glands can provide earthing, grounding, insulation, bonding, and strain relief.
