What is the difference between a Junction Box and a
Marshalling Box?
Answer Posted / engr. l. o. osuji
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.

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
