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.

the same but it may include electronic devices, switheches,
cards, fuses etc.

between supplier and distributor.

Answer / vijay shinde

junction box is used in house hold.but marshalling box is
