The maximum permitted size for DETD fuses for the feeder is what amperage?

• A. 250
• B. 300
• C. 200
• D. 225

Answer: (A)

The maximum permitted size for DETD (Distribution Equipment Thermal Device) fuses for the feeder is typically established based on the electrical code and industry standards, which prioritize safety and the prevention of overcurrent conditions. In this context, the choice indicating 250 amperes is correct, as it aligns with the standards for protecting conductors and equipment in feeder applications. This value ensures that the feeders can safely handle the load while providing adequate protection against overloads. Exceeding this maximum fuse size can compromise the protective measures in place, risking overheating and potential damage to the electrical system or equipment. By using a 250-amp fuse, you maintain the balance between operational capacity and safety, ensuring that the system operates within its designed parameters.
