Active Projects	Active P3004.3 - IEEE Draft Recommended Practice for the Application of Low-Voltage Fuses in Industrial and Commercial Power Systems This recommended practice covers the selection and application of low-voltage fuses used in industrial and commercial power systems.
	Active P3004.7 - Recommended Practice for the Protection of Conductors Used in Industrial and Commercial Power Systems This recommended practice covers the protection of conductors used in main and branch power circuits in industrial and commercial power systems against damage from short circuits and overloads as well as against physical damage from mechanical hazards, adverse environmental conditions, and improper handling.
Existing Standards	Active 3004.5-2014 - IEEE Recommended Practice for the Application of Low-Voltage Circuit Breakers in Industrial and Commercial Power Systems Information for selecting the proper circuit breaker for a particular application is provided. Application engineers are aided in specifying the type of circuit breaker, ratings, trip functions, and accessories. Circuit breakers for special applications, e.g., instantaneous only and switches are discussed. In addition, information for applying circuit breakers at different locations in the power system and for protecting specific components is provided.
	Active 3004.8-2016 - IEEE Recommended Practice for Motor Protection in Industrial and Commercial Power Systems The protection of motors used in industrial and commercial power systems is covered. It is likely to be of greatest value to the power-oriented engineer with limited experience in the area of protection and control. It can also be an aid to all engineers responsible for the electrical design of industrial and commercial power systems.
	Active 3004.1-2013 - IEEE Recommended Practice for the Application of Instrument Transformers in Industrial and Commercial Power Systems The selection and application of instrument transformers used in industrial and commercial power systems are covered in this recommended practice.
