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.
