Requirements in electrical distribution systems that need selective coordination

Selective coordination is required for installations that have power supplying a critical system. Learn more about design here.

ATTENDEES QUALIFY FOR A CERTIFICATE OF COMPLETION OR 0.1 CONTINUING EDUCATIONAL UNITS (CEU) AFTER SUCCESSFUL COMPLETION OF A TEST FOR MYSCHNEIDER PORTAL MEMBERS.

When designing electrical distribution systems, selective coordination is a fundamental piece to ensuring the reliable operation of electrical systems and safeguarding against the cascading effects of faults. Dive into the intricacies of NFPA 70: National Electrical Code, and other NFPA requirements for coordination, time-current curves and optimizing systems for selective coordination.

Learn about the requirements, limitations and best practices of selective coordination.

Learning Objectives:

Upon completion of this webinar, participants will be able to:

  • Identify:
    • NFPA 70, 99 and 110 requirements for coordination.
    • The instantaneous trip functions of circuit breakers.
    • The limitations of using time-current curves to achieve selective coordination.
  • Determine how to:
    • Use short circuit selective coordination table data.
    • Optimize system designs for selective coordination.
