Bus ties serve as crucial components in electrical distribution systems, as their primary purpose is to connect two or more switchboards. This connection enhances the reliability and flexibility of power distribution within a facility. By linking multiple switchboards, bus ties allow for the parallel operation of systems, ensuring that if one switchboard experiences a fault or requires maintenance, the others can continue to provide power, thus maintaining system functionality.

Additionally, connecting switchboards through bus ties facilitates load sharing among multiple power sources, helping to balance the electrical load and reduce the risk of overloading any single switchboard. This is particularly important in complex electrical systems where redundancy and reliability are paramount.

In contrast, while other options mention components and functions related to electrical systems, they do not accurately represent the specific role of bus ties, which is focused solely on connecting switchboards for improved power distribution and system resilience.
