Which device will open first if a high temperature condition exists on an electric furnace?

Question

Quizplus · Accepted Answer

In an electric furnace, the limit switch is the device that will open first if a high temperature condition exists. The limit switch is designed to protect the furnace from overheating and is set to open when the temperature reaches a certain level. This helps prevent damage to the furnace and ensures the safety of the occupants in the building. The other options listed (fusible link, high-pressure control, and interlock) are all important safety devices in their own right, but they are not specifically designed to respond to high temperature conditions in an electric furnace.
