How many casualty terminals are supplied with each of the power distribution switchboards?

The provision of two casualty terminals with each power distribution switchboard is standard practice for ensuring flexibility and reliability in electrical distribution systems. Having two terminals allows for the connection of multiple circuits or for redundancy if one terminal experiences failure or requires maintenance. This configuration accommodates the needs of various operating conditions and enhances the safety and efficiency of the power distribution network. By having two terminals, operators can effectively manage power loads and establish connections to different areas or equipment as required, which is crucial in maintaining a stable electrical system. This design consideration reflects the importance of adaptability and safety in modern electrical engineering practices.
