One of our primary responsibilities in the electrical trade is to select electrical conductors, and one of the primary responsibilities of electrical inspectors is to judge those selection decisions properly. Recognizing the importance of this issue, the task group appointed to review Article 220 for the 2005 NEC decided to recommend adding a new Example [...]
(No Ratings Yet)Inquiries from Parts I and II Is it a requirement that AFCIs be installed at the time of an electrical service change or upgrade to an existing installation? The enforcement of the AFCI requirements is a common question that must be communicated by the authority having jurisdiction. New dwelling construction or the addition of a [...]

Everyone who designs, builds or services electrical equipment is familiar with a crimp style connector. It is a basic component that is used to either connect or terminate wires. But, as often is the case in engineering, the items that seem simple oftentimes are not, and components that engineers, designers or electricians view as requiring [...]
(No Ratings Yet)The Canadian Electrical Code offers several ways to protect us from electrical shock hazards when electrical equipment may be within reach, in a wet or damp area, or near grounded metal. In some cases, we are asked to maintain “out of reach” distances. When this is impracticable, a Class A ground-fault current interrupter may help [...]

One of the most popular inspections in recent years to appear on the local municipal inspector’s daily list is the inspection of spas or hot tubs in the residential setting. Often the dwelling occupant or homeowner has installed the spa or hot tub. This combination of the well-meaning homeowner and the spa or hot tub [...]

Installing an incompatible wet-niche swimming pool luminaire (lighting fixture) into the forming shell in the wall of a swimming pool or spa can increase the risk of electric shock or injury to the users. The luminaire may physically fit into the forming shell, but the combination may not meet the applicable safety requirements. Manufacturers of [...]

It has been my pleasure and responsibility to be a member of National Electrical Code (NEC) code-making panel 2 (CMP-2) for nine NEC code cycles. Over this time, the code-making panels have produced the codes for 1981, 1984, 1987, 1990, 1993, 1996, 1999, 2002 and they are now working on the 2005 edition of the NEC. In this article, I will describe some of my experiences on this panel as well as some of the important code rules that have been introduced into the NEC by CMP-2 over the years.

It is that time of the Code cycle again. Over 3,580 proposed changes were submitted to the National Fire Protection Association (NFPA) to amend the 2002 National Electrical Code (NEC). The 2005 NFPA-70 committees have been reduced from twenty code-making panels (CMP) to nineteen as a result of shifts in responsibilities in an effort to [...]

Electrical circuit wiring requires building a proper path in which the electrical current can flow. Some fundamentals of electrical circuits are common to all circuits, including high voltage neon secondary circuits. One basic fundamental is that for current to flow, there must be a source (voltage) and a circuit that is complete and connected to [...]
