Circuit Breakers and Fuses Crossword Puzzle

QUESTIONS LIST:

• overcurrent protection : the application of components such as circuit breakers and fuses to safely de-energize a circuit when the current exceeds a predetermined value.
• fuse link : the fusible (meltable) part of a cartridge fuse.
• frame size : a method used to classify circuit breakers according to current ranges.
• fault current : the current that exists when an unintended path is established between an ungrounded conductor and ground.
• nonrenewable fuses : fuses that must be replaced after they interrupt a circuit because the fusible link cannot be replaced.
• pole : a portion of a device associated exclusively with one electrically conductive path of a circuit or component.
• circuit breakers : devices designed to open and close a circuit manually or automatically when a predetermined level of current exists, without damage to themselves when properly applied.
• cartridge fuse : a fuse enclosed in an insulating tube to confine the arc that occurs as the fuse opens under load.
• fuses : overcurrent protective devices with fusible (meltable) components that melt and are thereby severed by the passage of current beyond their rating.
• molded-case circuit breaker : a circuit breaker enclosed in an insulating housing.
• plug fuse : a fuse with a threaded body, screwed into a fuse holder to secure it.
