    Top 2005 Code Changes
    110.12 -- Mechanical Execution of Work
    By Mike Holt
    This section requires electrical equipment to be installed in a "neat and workmanlike manner," but the Code doesn't provide details on what that means. A new FPN gives the Code user a reference to an ANSI standard on the subject of installation workmanship.

    What the Code says: Electrical equipment must be installed in a neat and workmanlike manner.
    FPN: Accepted industry practices are described in ANSI/NECA 1-2000 Standard Practices for Good Workmanship in Electrical Contracting, and other ANSI installation standards.

    (Modified Code wording is underlined.)

    Behind the change: NECA has created a series of National Electrical Installation Standards (NEIS) that establish the industry's first quality guidelines for electrical installations. These standards define a benchmark or baseline for quality and workmanship for installing electrical products and systems. They explain what installing electrical products and systems in a "neat and workmanlike manner" means.

    Nightmare Installations
    The Customer Isn't Always Right
    Last issue we asked you for your scariest or funniest holiday lighting stories. Although not technically an installation, the following submission was our favorite.

    While working for Home Depot in the electrical department for two Christmas seasons I encountered a handful of customers with a specific problem: They were perplexed that they could not find an adapter with male plugs on both ends that they could use to connect strings of Christmas lights. I explained that the item they were looking for was not even made. I even had one customer who wanted to know how they could get one made and market this item to the store. After I explained the electrical hazard that this would create some would assure me that they would tape up the exposed prongs on the end of the cord at the top of the tree or at the end of the string attached to the house. I had to point out that the best -- and safest -- solution was to remove the lights and reinstall them female to male and so on.

    Ultraweld TOP-LIGHT Mold Cover
    Harger introduces TOP-LIGHT, a new mold cover design that greatly improves the ignition process for Ultraweld exothermic connections. TOP-LIGHT makes the ignition process easier to perform while substantially reducing the reaction emissions. Use of the TOP-LIGHT cover eliminates fouling of the flint igniter and substantially extends the life of the igniter. Ph: (800) 842-7437. Website:

    Q. I heard that the Code only permits one equipment grounding (bonding) conductor to terminate on a grounding block screw terminal. Is this true?

The rugged steel construction has a zinc electroplate finish. The fittings install with standard electrician tools and methods. For information, call 800-621-1506. E-mail:

    Faces of the Code
    Bruce McClung
    Member, Code-Making Panel 6

    A list of electrical industry "giants" contributed to Bruce McClung's career as an electrical engineer, and he's proud to name them. He speaks with reverence of the men who taught him to respect but not fear electricity, and he readily admits that their tutelage inspired him to work to improve electrical safety throughout the industry. "Without them, I would have remained somewhere in the middle section of the engineering ranks," he says.

    It was Francis Fox, an engineer at General Electric in the '60s, who introduced McClung to the concept of using high-resistance grounding to maintain safety in the industrial production environment at Union Carbide Corp. (UCC) where he worked for more than 40 years until 2001. And although his superiors were skeptical of the concept, they eventually relented and implemented it at all of their facilities once McClung demonstrated its merits. That pioneering spirit with regards to electrical safety is what ultimately helped him reach the title of "corporate fellow," something no other electrical engineer at UCC had ever accomplished.

    And it was Bernard Whittington, a fellow engineer at UCC, who showed McClung the importance of participating in standards-making committees by taking him on as his assistant while helping to establish OSHA regulations. That experience cultivated a desire to join electrical safety committees throughout his career, including several IEEE standards-writing bodies and Code-Making Panel 6, which he's served on since the 1978 cycle. "The willingness of mid-level managers to support engineers who were involved in developing the standards and regulations by which they were to be monitored and measured relative to safety and productivity influenced my tenure at UCC," he says.

    Now, at the age of 67, McClung is the co-owner of two electrical consulting service companies -- Electrical Safety Consulting Services and Mc Squared Electrical Consulting -- where he's taking those lessons and applying them to solve hazards he might not have imagined when he was still learning from Fox, Whittington, and others. With arc flash now a chief concern in industrial environments, he's still committed to improving electrical safety, which is why he's still working when many would be enjoying retirement. "Electrical safety is still in its infancy, ready to become a teenager," he says. "And I'll continue to do this work until it comes of age and matures to be a part of everyone's cultural heritage.

    Cool Electronic Cabinets
    Low cost Cabinet Coolers stop electronic control downtime due to heat, dirt and moisture. UL Listed Cabinet Coolers produce 20 degree Fahrenheit air from an ordinary supply of compressed air to cool electrical controls. Thermostat control minimizes air usage. Maintains the NEMA 4, 4X (stainless steel) and 12 rating of the enclosure. Web site offers detailed information, downloadable drawings and PDF literature.

    Speak Out
    Lights Out, Part 2
    CodeWatch readers are evenly divided over whether homeowners should be held to the 90-day limit on holiday lights mandated by 590.3(B) of the NEC.

    The question, then, is how to enforce this rule. Chances are good that most homeowners aren't aware of it, so what should be done to make sure they adhere to it? Should electrical inspectors be expected to monitor holiday lights in their areas and issue warnings or citations as needed? Visit EC&M's Web site to tell us.
