This presentation will cover UL® 508A procedures outlined in Supplement SB to determine the short-circuit current rating of an industrial control panel. Examples and practice problems will be provided to further enhance the concepts.
This presentation will cover the basic code requirements for equipment short-circuit current ratings (SCCRs) and the 2020 NEC®, including definition and key requirements. In addition, marking and documentation requirements are discussed for available fault current for various types of equipment.
This course covers the difference between a motor controller and a motor disconnect. AUX contacts, early break vs. break after main break... which one should be used with VFDs? Various types of motor control, fused, non-fused, mechanical interlocks, power indicating, non-metallic, stainless steel, and hazardous location applications will be covered.
The class will discuss different types of home automation products and their protocols. Learn about the future of home automation and how to be profitable selling these products in a residential contractor market.
Overview of how Meltric’s Switch Rated Devices simplify meeting NFPA 70E requirements, including efficiently providing arc flash protection for motors, welders, pumps and more, even in wash down environments.
This presentation will cover the motor circuit and various devices that can be used. A through explanation will be given as to the proper application of disconnects switches, fuses, branch-circuit and supplemental, molded case circuit breakers, motor circuit protections, combination motor controllers and more.
The requirements for selective coordination in the NEC will be addressed. Time current characteristics of overcurrent protective devices will be explained and the process of achieving selective coordination with circuit breakers and fuses will be discussed. Participants will learn how to easily avoid unnecessary blackouts in facilities.
Learn to analyze the protection of electrical system components from fault current. This presentation uses withstand ratings of specific components such as motor starters, wire, busway, etc., enabling the engineer to comply with Article 110-10 of the National Electrical Code.
Learn the "when, where, and how" of sub-metering. Understand the hardware and the communication systems which make up and support sub-metering. Maximize efficiency with software tools. Students will be able to tie together all they've learned to create a solution.
