• A Buck-Boost transformer cannot be used to develop a three phase, four wire wye circuit from a three phase, three wire delta circuit. • Buck-Boost transformers cannot be used in a closed delta connection. • Buck-Boost transformers should not be used to correct for voltage drop on a long circuit run where the load fluctuates. • Buck-Boost transformers cannot be used to create a 240/120 Volt, single phase service from a 208Y/120 Volt three phase supply.
