Universal Trip Units may be ordered with a limited set of
options. It is suggested that they be ordered with the widest
range of options used within a facility, as any unnecessary
functions can always be disabled or turned off (except for
Ground Fault) during set up by the user. The user-selected
options for the Universal Trip Unit are listed in Table 3.18.
