Fusing Buck-Boost Transformers
"450-4, Autotransformers 600 Volts, Nominal or Less. (a) Overcurrent Protection. Each
autotransformer 600 volts, nominal or less shall be protected by an individual overcurrent device
installed in series with each ungrounded input conductor. Such overcurrent device shall be rated or
set at not more than 125 percent of the rated full-load input current of the autotransformer. An
overcurrent device shall not be installed in series with the shunt winding ...".
"...Exception. Where the rated input current of an autotransformer 9 amperes or more and 125
percent of this current does not correspond to a standard rating of a fuse or non-adjustable circuit
breaker, the next higher standard rating described in Section 240-6 shall be permitted. Where the
rated input current is less than 9 amperes, an overcurrent device rated or set at no more than 167
percent of the input current shall be permitted...".

KVA or Ampere Rating of the Load
Find either the load KVA or the load amperage requirements. This information is listed on the
nameplate of the load equipment.
Frequency
Either 50 or 60 Hz. The frequency of the transformer must match the frequency of the load.
Number of Phases
Single or three phase line and load must match. (A transformer cannot convert single to three
phase.) A common application is to make a single phase connection from a three phase supply
by using one phase of the three phase supply circuit. Be careful not to overload that phase of
the three phase supply. For buck-boost applications the supply must provide load KVA - not just
the nameplate rating of the buck-boost. Refer to the Selection Tables.
