Which connection diagram would deliver 220 volts to equipment rated for 220 volts if the supply circuit is 206 volts?

In order to deliver 220 volts to a piece of equipment that is rated for 220 volts when the supply circuit is only providing 206 volts, it is essential to use a connection diagram that allows for voltage boosting or a suitable adjustment to accommodate the lower supply level.

The connection diagram that successfully achieves this would likely involve a method to elevate the voltage supplied to the equipment. Such connections can include auto-transformers or secondary winding transformers that can step up the voltage from the supply level, thus providing the necessary voltage to the equipment despite the supply being lower than required.

In this particular scenario, Diagram 3 efficiently shows a connection that regulates, transforms, or otherwise adapts the incoming voltage of 206 volts to provide the correct voltage of 220 volts. This would be vital for protecting the equipment and ensuring it operates correctly without damage, adhering to the requirement for precise voltage specifications in electrical work.

Utilizing the appropriate connection diagram is crucial in ensuring that equipment operates effectively within its specified voltage tolerance while also addressing any deficiencies in incoming supply levels.
