usually rectangular in cross section. Busbars are used
inside switchboards where it is normally not insulated but
protected from access by panels. The busbars are mounted on
insulating blocks.

A bus duct is an enclosure which contains a number of
busbars (phases, neutral and earth). It is used for

to protect the busbars from being touched. the busbars are
also held in insulating blocks.
