what is a high leg transformer?

A high leg transformer, also known as a „wild leg“ transformer, is a type of three-phase transformer used in electrical systems to provide a 120/240V split-phase output. It features one phase that has a higher voltage (typically 208V) relative to the neutral, which is useful for powering both single-phase and three-phase loads. This configuration is commonly found in commercial applications where specific voltage requirements are needed for equipment.
