It'll be about 4X5X6 inches (for proper rating), usually painted
gray, and will have a terminal diagram that shows connections
for 120/240 on the primary and 12/24 on the secondary. Usually
they mount to the wall, with connection covers on the top and/or
bottom.

What you will be doing is hooking the secondary in SERIES with the
the load to boost or buck the voltage depending upon which
polarity you hook up either the primary or secondary.
