What type of device transfers load conductor connections from one power source to another?

A transfer switch is specifically designed to transfer load conductor connections from one power source to another. This device is crucial in situations where you need to maintain power continuity, such as during a power outage or when operating backup generators.

Transfer switches can automatically or manually switch the load from a primary power source, like utility power, to a secondary source, such as a generator. This capability ensures that electrical loads are safely managed and that there is no risk of backfeeding power into the grid, which can pose significant safety hazards.

In contrast, a switchboard serves as a central hub for distributing electrical power but does not necessarily transfer connections between different sources. Circuit breakers are crucial for protecting electrical circuits from overload or short circuits but do not manage multiple power sources directly. A fuse box performs a similar function by housing fuses to protect circuits, but it also does not provide the function of transferring load connections between sources. Thus, the transfer switch is uniquely suited for the task described in the question.
