What is the maximum size of the fuses that can be installed in Safety Switch #1?

To determine the maximum size of the fuses that can be installed in Safety Switch #1, one must refer to the manufacturer's specifications for that specific switch. Safety switches are designed to handle a maximum current load safely, and exceeding this load can result in overheating, equipment failure, or even fire hazards.

In this case, if the correct answer is identified as 400 amps, it signifies that this is the upper limit set by the manufacturer for the fuses in Safety Switch #1. Utilizing fuses at this specified maximum ensures proper operation and safety of the electrical system.

Fuses rated over this limit may not only void warranties but can also compromise the safety functions that the switch is designed to provide. Hence, adhering to the established specifications is crucial for maintaining the integrity of the electrical installation and ensuring compliance with electrical codes and standards.
