Through which means can an SDC receive power?

An SDC (Secondary Distribution Center) is designed to receive power from multiple sources to ensure reliability and flexibility in the electrical distribution system. The correct answer acknowledges that an SDC can receive power not just from a primary distribution center (PDC) but also from another SDC and a low voltage generator.

This flexibility allows for redundancy and ensures that if one source fails or is unavailable, the SDC can still maintain power distribution from one of the other sources. Receiving power from another SDC can be particularly advantageous for balancing loads and enhancing the reliability of the overall electrical system.

Using a low voltage generator further expands the options for an SDC, providing a means to support operations during outages or when grid power is insufficient. Therefore, the capability to receive power from PDCs, other SDCs, or low voltage generators forms a robust framework for electrical power distribution.
