What is a Junction box and Its Applications?

What is a Junction Box? 

If you aren’t certain about what the junction box is, don’t worry, most people don’t know. There are precious few who work directly with this type of equipment like we do at Box Electric Company. That said, everyone should get a little education about what this type of equipment is so that they can start to use it in their daily life. 

A junction box is an intermediary between process field instruments and equipment used to monitor field instruments. In other words, the box is useful for helping to control the processes between the equipment that is used out in the field and the equipment that is used to control that equipment.

What is the Importance of the Junction Box in an Instrument Control System? 

There are some situations when it is necessary to get a handle on the wiring of the instruments that you are using out in the field, and a great way to make that happen is to use a junction box to make sure it is as easy as possible to control field instruments from a centralized control room. 

People in the industry will tell you that they need the centralized controls that junction boxes help provide them, and you will want to know a bit more about the usefulness of junction boxes. 

How Field Instruments Are Wired to the Junction Box 

Instrument cables are wired through the junction box at the bottom. They are twisted wires that need to be looped in through the bottom of the junction box to work properly. The wires also need to be cut properly to ensure they fit the junction box they are shaped for. 

The wires and cables are tagged and labeled so those who hook them up can do so without getting it confused. These are very delicate wires, and it is important to make sure they are hooked up exactly how they need to be so that there isn’t any confusion about which wires go where. Those trained in how to do so will certainly come up with some ways to ensure the boxes get wired up just right.
