Terminal Extension Kit
A terminal extension kit is
used to allow front access
to the rear terminals on most
500 and 750 kVA transformers
(transformers on frames 919
and 920) when insufficient
space is available at the rear
of the transformer. Eaton
recommends a minimum
6-inch clearance from the wall
to maintain proper ventilation.
