What does a yellow tower beacon signify about the generator?

A yellow tower beacon indicates that the generator is in a state where it is operational and has an active load. This signaling is critical for operators and maintenance personnel as it provides immediate visual feedback about the generator's status. When the load is active, it means that the generator is producing power and supplying it to connected electrical systems or equipment.

While other signals or colors may denote different statuses, a yellow beacon specifically means the generator is functioning and is currently in use. This is especially useful in environments where multiple generators or electrical systems operate simultaneously, allowing for quick identification of their operational status without needing to consult control panels or other monitoring equipment.
