Can a "Buck-Boost" transformer be used to operate a 240-volt rated load on a 208-volt supply voltage?

A "Buck-Boost" transformer is specifically designed to adjust voltage levels, allowing a load rated for one voltage (in this case, 240 volts) to operate on a different supply voltage (208 volts). This type of transformer can increase (boost) or decrease (buck) voltage to match the requirements of the load.

In situations where the supply voltage is lower than what is required by the load, a Buck-Boost transformer can effectively boost the voltage from 208 volts to the necessary 240 volts. This is particularly useful in commercial and industrial applications where machinery and equipment are designed to operate at higher voltages.

Using a Buck-Boost transformer offers several advantages, such as improved efficiency and reduced strain on the electrical equipment by providing the correct voltage. This means that the load can operate safely and effectively, without the risks associated with under-voltage, such as reduced performance or potential damage.

The other options do not apply because the Buck-Boost transformer is adequate for direct voltage adjustment without needing additional conditions or equipment.
