Circuit Protection Devices

COURSE NO: E03-005
PDH CREDIT: 3
COURSE PROVIDER: A. Bhatia
Circuit Protection Devices
Course Highlights

This online engineering PDH course describes how a proper circuit protection strategy reduces long-term maintenance needs and costs, and minimizes system downtime.

 

Too much current flowing through an electric circuit can damage the circuit and can create a safety hazard. How much current is "too much current"? That depends on the circuit and its components. For some circuits, 1 ampere would be too much current, while for other circuits 1 ampere would be perfectly acceptable. A proper circuit protection strategy reduces long-term maintenance needs and other costs, and minimizes system downtime. Circuit protection devices protect electrical equipment by rapidly disconnecting power to components in the event of an abnormal overload conditions resulting from excessive voltages, ground faults, and accidental shorting of a circuit.

 

This 3 PDH online course is applicable to students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers who are interested in gaining a better understanding in circuit protection.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • State the reasons why circuit protection is needed
  • Define a direct short, an excessive current condition, and an excessive heat condition
  • State the way in which circuit protection devices are connected in a circuit
  • Identify two types of circuit protection devices and learn their types and characteristics
  • List the three time delay ratings of circuit breakers
  • Define selective tripping and state why it is used
  • Identify the factors used in selecting circuit breakers
  • List the methods of checking and the items to check when replacing and/or maintaining fuses and circuit breakers.
