Code Making Panel 2 recognized the need for arc-fault circuit-interrupter (AFCI) protection when it accepted proposals and accompanying substantiation for the 1999 National Electric Code. Now, as the January 1, 2002, implementation of AFCI requirements in Section 210-12 of the 1999 NEC rapidly approaches, the technology and level of protection provided by various types of [...]

The purpose of the grounding portions of Article 517 of the National Electrical Code (NEC) is to reduce low voltage potential differences between electrically conductive surfaces that may be reached by a patient or care provider in the patient vicinity. Two independent means of grounding are required for the patient care areas and are connected [...]
(1 votes, average: 5.00 out of 5)Introduction The National Electrical Code (NEC), sometimes referred to as NFPA 70, is the preeminent code covering electrical installations in the United States and in many other countries. Section 90-1(b) of the 1999 edition says: (b) Adequacy. This Code contains provisions that are considered necessary for safety. Compliance therewith and proper maintenance will result in [...]
(No Ratings Yet)The American National Standards Institute (ANSI) — Most in the electrical industry have heard of it, but do you really know what it does? Take the following short quiz: The American National Standards Institute is: (a) A standards developing organization (like UL, IEEE, NFPA, etc.) (b) A facilitator of standards development (c) A federal government [...]

The first modern neon sign debuted in 1910 at the Grand Palais in Paris. It was created by a Frenchman named George Claude, who somewhat stumbled upon his discovery by accident. His purpose was actually to employ an inexpensive, high quality method of producing pure oxygen to sell to hospitals and welding shops. Wanting to [...]

Proposals submitted to change the 2002 Code are included in the NEC Report on Proposals. That document is available from the National Fire Protection Association. Those who wish [...]
(No Ratings Yet)Section 90-1(c) is often cited in arguments against submitted Code proposals. In many instances, it is the only defense against proposals, even though the proposals also contain recommended safety rules. One only has to look in previous editions of the NEC Report on Proposals and NEC Report on Comments to see how frequently this reference [...]
(No Ratings Yet)IAEI members and associated organizations rose to the occasion to make possible the completion of a construction project at the IAEI headquarters building in Richardson, Texas. Finishing the second floor area to create an educational facility has provided a more suitable environment in which to conduct meetings and perform training. In a previous editorial, those [...]
(No Ratings Yet)Computer signals are made up of a combination of zeroes and ones, and they are often below five volts DC. Voltage noise and voltage transients can disrupt the correct flow of electronic data, even when it is as low as two to three volts. A zero may be one to 1-1/2 volts and a one [...]
