Procedures for Inspecting Switchgear

What’s big, gray, and should be approached carefully? If you answered "an elephant,” why are you reading an electrical book? If you answered "switchgear,” you’re probably a code weenie. Inpectors often ask, "What are the procedures for inspecting switchgear?” Like eating an elephant, the best approach is one bite at a time.

The Fire Never Started – Thank an Inspector

The general theme for this month’s IAEI News is safety; and when most electrical people talk safety, they think of personnel safety and safety in the work place, OSHA and NFPA 70E. And why not, after all electricity is dangerous and if you’re not careful working with it you can get hurt.

2008 International President: Robert McCullough

There are two kinds of people in the world, those who sit back and wonder what happened and those who stand up and make things happen. Make a difference—get involved!”

Article 675 – Electrical Driven or Controlled Irrigation Machines

Welcome to the Rodney Dangerfield of NEC articles! Irrigation machines? Most of you will labor your entire electrical careers without ever having seen one of these, let alone inspect or wire one. Back in 1973, proposal number 115 was submitted to code-making panel 11 by the Technical Subcommittee on Electrically Driven Center-Pivot Irrigator Systems. This proposal was to add a new article 675 to put in place requirements that dealt with the unique characteristics of this type of equipment. It is no surprise that it was proposed for Chapter 6; if this isn’t special equipment, I don’t know what is.

Wiring Methods and Overcurrent Protection

One of the most fundamental elements of an electrical installation is the connecting of the wiring method to an overcurrent device. Seems simple right? All most people seem to do (including inspectors) is to look at Table 310.16 and match up the numbers to a fuse or breaker. Unfortunately the actual selection process can be much more complicated than that.

If I were a Manufactured Home, what Code Would I Use?

If you answered the National Electrical Code, you would be partially correct. Manufactured housing has its own set of construction standards that are found in 24 CFR Part 3280. This came into being in response to the National Manufactured Construction and Safety Standards Act of 1974 (42 U.S.C. 5403). These original rules were, for the most part, transcribed from the 1977 edition of NFPA 501B, Standard for Mobile Homes.
