From the application point of view there is no difference between junction box and marshaling box. Both are used for termination and connection of cables between different points. Usually, in the low voltage ubstation it is called junction box and high voltage substation it is called marshalling box.
Conventional Junction box. Convectional Junction box contains Terminal Strip and Earth Strip/earth bus bar only. Instruments field pair / core cable (From Instruments to Junction Box for transmitters, switches, valves, solenoid valve etc.) is terminated at one side of terminal strip and multi-pair cables (From Junction box to Marshalling cabinet/system cabinet/control .In a junction box implementation, there is a minimum of 4 additional terminations per IO. This cost is magnified when considering all of the additional cabling and raceways it takes to wire between the junction boxes and PLC cabinet. All of these factors result in additional field labor and consumable construction materials.In classic signal marshalling, the field signals arrive in any order and are sorted according to their signal type. The marshalling level is wired to the interface level, which in turn is wired to the I/O level. Here, recurring problems in terms of specification, operation, maintenance, and cost arise due to the complexity of signal marshalling.
Heating cable junction and marshalling boxes. MBOX Power Marshalling Box. The Chromalox MBOX is a marshalling box used to feed power to a group of heat trace cables, and is available to use from 120V-600V supply voltages. This NEMA 4X fiberglass junction box provides a water and dust-tight seal as well as resistance to chemical contaminants.Marshalling Boxes/Kiosks/Junction boxes are used in substation switchyards provided with Terminal Blocks to which control cables are connected. Marshalling means grouping of I/Os. Marshalling panel is placed between the DCS system panel and field instruments. .

A marshalling cabinet is a type of electrical enclosure that is used to organize and terminate field wiring in an industrial process control system. A marshalling cabinet is typically used in systems that have a large number of input and output (I/O) points, such as programmable logic controllers (PLC) and distributed control systems .
The cables between the field junction box and the marshaling panel must be routed in conduits or trays or they should be directly buried. The major purpose of the marshaling cabinet is to do the main cable termination and then to redistribute the field device to its I/O cards with the help of internal wiring. The multi-paired wires from the .
