Hi Cindy,
Junction boxes are used in domestic wirings especially when
supply is to be taken through a switch to a lamp holder or
from one room to another.
Marshalling boxes better called Marshalling Kiosks(MKs) are
used in substation switchyards and in power transformers.
For switchyard MKs they contain terminal blocks to which
control cables are connected. They may also contain mcbs
and other devices. The same is true for transformer MKs.

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.

Answer / manas datta

By name and application, Junction box is used simply for
junction of cables / wires. Marsheling box is also used for
the same but it may include electronic devices, switheches,
cards, fuses etc.

Answer / marzi nasrizade

Actually both of them are the same in action, they are used for termination and the difference is the load duty.
Marshaling box is used for heavy duty.

Answer / priyanka chakraborty

Junction box is mainly used for household wirings such as low voltage application.
Marshaling box is used for high voltage application. In substation or switchyard power, control and instrument cables are connected to marshalling box.

Answer / manish panchal

JUNCTION BOX IS USED FOR TAPPING FOR CT AND PT SUPPLY IN
SWITCHYARD. IT ALSO USED IN CONTROL TERMINALS, IT ALSO USED
AS A JOINT.

MARSHALLING BOX IS USED IN OUTDOOR APPLICATION LIKE T/R
M.BOX USED WITH WTI AND OTI IT IS ALSO USED BIG M.BOX FOR
CT/ AND PT CONNECTION.

Answer / k.prakashchandra

Another difference is that marshaling box is at the
beginning and junction box is in the middle, just like
between supplier and distributor.

Answer / vijay shinde

junction box is used in house hold.but marshalling box is
used in transformer where WTI,OTI &FAN CONTROL ARE PLACED

we have two generators different capacity on 15 MW and other 6MW at 11 KV , 15 MW gen. bus short level current 40KA,and 6MW short level current 25KA,, length of cable 100MTR between 6 MW from 15MW gen. for bus coupling . kindly tell any one can we use both NGR OR one NGR from any GEN. BOTH NGR has diff. rating. Tariq pakistan
