NFPA 
            70B: Recommended Practice for Electrical Equipment Maintenance,
			
			2019 Ed.
            Apply the 2019 edition of NFPA 70B along 
			with NFPA 70E® to maintain electrical 
			systems correctly and safeguard your personnel, your facility, and 
			your business.  
			Electrical systems maintenance helps protect 
			workers, avoid equipment downtime, and reduce the cost of repairs. 
			In fact, proper maintenance is absolutely essential to the safety of 
			your facility and your employees.  
			Get guidance you can trust in NFPA 70B, 
			Recommended Practice for Electrical Equipment Maintenance. 
			 
			NFPA 70B details 
			preventive maintenance for electrical, electronic, and communication 
			systems and equipment -- such as those 
			used in industrial plants, institutional and commercial buildings, 
			and large multi-family residential complexes.
			Used alongside the requirements in
			NFPA 70E®, Standard for Electrical Safety 
			in the Workplace® NFPA 70B helps facility managers develop and carry 
			out an effective Electrical Preventive Maintenance (EPM) program for 
			all types of equipment and assemblies. Contractors look to NFPA 70B 
			for information about properly servicing equipment, and designers 
			depend on it for developing specifications for installation that 
			take maintenance into account. 
			Updates in NFPA 70B 
			coordinate with NFPA 70E and the "dot" standards from the Institute 
			of Electrical and Electronics Engineers (IEEE). 
			
				- New recommendations for performing a 
				maintenance-related design study correlate with the latest 
				edition of NFPA 70E.
 
				- New references help you identify content 
				covered in approximately 70 IEEE "dot" standards in the IEEE 
				3000 Standards Collection™, replacing references to the IEEE 
				Color Books.
 
			 
			NFPA 70B chapters 
			address every aspect of equipment maintenance: 
			
				- Planning and developing an Electrical 
				Preventive Maintenance (EPM) program
 
				- Personnel safety
 
				- Fundamentals of electrical equipment 
				maintenance
 
				- System studies
 
				- Power quality
 
				- Testing and test methods
 
				- Maintenance of electrical equipment 
				subject to long intervals between shutdowns
 
				- Ground-fault protection
 
				- Grounding
 
				- Plus detailed chapters on many different 
				types of assemblies, equipment, cables, and devices
 
			 
			Stay focused on safety and your bottom line 
			with NFPA 70B. Maintain equipment and develop your EPM using the 
			latest guidance from the field
