One of the most common types of junction boxes is the standard rectangular box, often used for light switches and receptacles in residential and commercial buildings. Usually made from metal or plastic .
are electrical boxes and cabinets made of metal (e.g., steel, galvanized steel, aluminum, and so on) or non-metallic (plastic) materials that provide protection for conductors, connections, controls, and other electrical equipment. A junction box in the instrumentation field is a device that would act as an interconnecting medium between the process field instruments and the equipment which is used to control and monitor the field instruments, this equipment would be located in the control room. Mostly the junction boxes are used to terminate the multiple field devices of .
Instrument cabling usually runs from the control room to the plant area (either below or above ground) in multicore cables and then from field junction boxes in single pairs to field measuring or actuating devices. Cabling requirements: They should be kept as short as possible.They should not cause any obstruction to prohibit access to personnel .
In the following figure below there are various types of field instruments connected to the control room via a field junction box. A close picture of the connection from a starting point to the destination is shown in it. Instrument signals can be carried by wiring with a conductor size of at least 18 AWG is recommended.Instrument cable schedule; Junction box tagging philosophy; Cable Tagging. The below discussed the different ways where we used the cable tagging. Field Instrument to Junction Box. Individual cables running between field instruments and junction boxes are normally identified by the instrument tag number itself. Example: Junction Box to Control RoomMain cable (i.e. from Junction box and control room) shields shall be grounded at one place i.e. control system end Instrument earth bar Isolated type. All the connections to the Instrument Earth bar within the cabinet shall be of screw .
