The chief electrician (chief LX) of a
play,
concert, or other kind of
show, is the person
responsible for everything
electrical above,
on, or
in front of the
stage. It is his job to make sure that everything is
safe, and that nobody is going to get
electrocuted. The chief LX will often run the
lights for the
show as well, although for
larger productions, there is often a specific
lighting operator for this (the other main member of the
lighting team is the
lighting designer)
Overall
responsibility for
people in the
theatre is held by the
stage manager, but he will usually delegate the
responsibility for the
people in the
proj box to the chief LX.
