Low voltage circuit breakers (1000V or less) play a crucial role in the protection of other power system devices. The need for maintenance of these circuit breakers is not always obvious because they remain idle for long periods of time. While deterioration is normal and begins as soon as the circuit breaker is installed, it can cause failures and malfunction without preventive maintenance. Proper maintenance and testing of electrical circuit breakers will enhance equipment life expectancy, reliability, and overall system performance.

Learning Objectives
• Maintenance requirements and justification

•Identify components and nameplate data for power circuit breakers equipped with electro-mechanical and solid-state trip devices

•Perform a complete circuit breaker service: inspection, removal, disassembly, cleaning, tightening, reassembly, lubrication and adjustment in lab

•Read and interpret manufacturers' trip curves, including RMS types

•Use high current test sets, perform contact resistance and meghometer testing in lab

•Evaluate test results

Who Should Attend
Designed for apprentices, technicians, engineers, and supervisors that are responsible for the maintenance and testing of low-voltage power circuit breakers.

Requirements
Requires working knowledge of basic electricity. Students must wear safety toe shoes.
