It seems like just yesterday that the NFPA Standards Council issued the 2011 National Electrical Code (NEC). However, we’ve moved on to the next one; the 2014 edition was up for approval in August. Revising the NEC is a ton of work for the 19 technical committees during each three-year development cycle. The NEC is in a continuous revision process due to its inherent dynamics. READ MORE

Occasionally, I provide training on electrical wiring in healthcare facilities, and frequently I am asked about the requirements for hospital-grade receptacles. One individual recently indicated that the medical building’s patient-care areas are being wired using hospital MC cable. READ MORE

At a recent training presentation on wiring for healthcare facilities, there was a question about protection for the emergency system in a hospital. An attendee asked if the emergency lighting circuits installed for 2-by-4-foot lay-in luminaires located in a suspended ceiling grid could be wired using MC cable or if they needed to be wired using metal raceway, such as EMT.

A recent training program discussed the requirements for connecting surge protection at service equipment. With the variety of opinions on this issue, it seemed appropriate to provide some information about connecting surge protective devices (SPDs) in a manner compliant with the National Electrical Code (NEC). Prior to the 2011 NEC, SPDs were known as transient voltage surge suppressors (TVSSs). READ MORE

Requirements for electrical wiring in hazardous (classified) locations are more restrictive than in the rules for wiring in general types of occupancies. National Electrical Code (NEC) Chapter 5 includes rules for special occupancies such as hazardous locations, healthcare facilities and assembly occupancies. Chapter 5 rules often modify or amend the general requirements in chapters 1 through 4. READ MORE

Preventive maintenance plays an important role 
in how long a product will provide trouble-free service and, ultimately, how long it will last. 
Nothing lasts forever, so the saying goes, but with some care and regular servicing and maintenance, products can provide 
normal anticipated operation. A good example of maintenance that lengthens life expectancy is a vehicle. READ MORE

Generators are commonly installed for buildings or structures requiring emergency systems, legally required standby systems or optional standby power systems. Some generators are located within the building or structure they supply; but, frequently, they are located outside. READ MORE

At a recent seminar, one of the attendees asked, “What is a ‘Ufer’ ground?” This is a common question. A “Ufer” ground is slang for what the National Electrical Code (NEC) addresses as a concrete-encased grounding electrode. The term “Ufer” does not appear in the Code, but many in the industry use it.

A long-standing requirement in the National Electrical Code (NEC) is to provide a service disconnecting means for each building or structure served by electricity. The concept is simple; the disconnecting means serves as a ready means for the occupant or other responder to remove all power from the building by operating the service disconnect. READ MORE
