Introduction to Circuit Protection Devices (Timed & Monitored)

A. Bhatia, B.E.

Electricity is part of our everyday lives but there are safety hazards associated with the electricity. Safety hazards occur anywhere a person could come into contact with electrical lines or equipment. As long as a person is touching the ground (or something in contact with the ground), electricity has the potential to travel through him or her, causing shock, burn, or even death. Fuses and circuit breakers are protective devices used to ensure that too much current does not flow through a circuit. A fuse or circuit breaker is designed to create an open circuit if too much current flows through it. You can think of it as a switch that automatically turns itself off if the current through it exceeds a certain level.

This course provides you with insight to how circuit protection devices work.

This 4-hr course material is based entirely on Naval Education and Training Materials (NAVEDTRA 14175), Electricity and Electronic Training Series; Module-3 “Circuit Protection Devices” and covers Chapter 2.

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
