It is True that although more expensive, open-circuit transition is preferable to closed-circuit transition because closed-circuit transition does not cause a high-current transition surge.

Explanation:

The difference between open-circuit transitions and closed-circuit transitions is that:

An open transition switch brings a "break before make" switch function. This means that the connection is established with the generator before the utility is shut off, and then the swap is made quickly once the connection has been safely established. Open transition switches are often regarded as the most cost-effective and widely used systems, as they are compatible and viable for most business operations and needs.

A closed transition automatic transfer switch performs a similar but slightly different function, using "make before break" features that make use of advancements in modern electrical technology. With these systems, the two power sources (utility and generator/backup) are allowed to briefly overlap, which limits or removes the momentary stutter in power that open systems can occasionally create.
