Re: Electrical Hazards in the Real World!
several of the posters have brought up related issues to the unforeseen consequences area and i will add a small list as well.
I think as others have also pointed out that the big problems arise from grouping different electrical conditions under one article, or amendment. Even if the NEC were to write an article concerning this it would have to be done for the different situations and conditions. This holds true if it were added to the maintenance code.
1. who gets to say that the wiring is abandoned? What are the actual criteria that separate and define abandoned wiring that should be removed, from wiring that may be not so abandoned. This will be, if implemented, administered by bureau crats like me, and others with little electrical experience, and of course the fanatics as well as the misreading fanatics. It will be adjudicated in courts by laymen, with experts of all ilks witnessing.
2. who is responsible for the wiring? The owner or previous owners, current electrical contractor.
3. I have not looked it up but was always taught that you had to do wire pulls in one piece, that you could not pull over other wires as it abraded them ( creating a hazard ), so how do the wires get removed or are the portions of wire ways that contain other wires to be rewired????? ( could you see the contract, add a light $465,000, just to be safe).
4. does the wiring that is to be considered abandoned include the wireways, boxes, equipment, supporting devices? many of these are incorporated into the structure, roofing, plaster, etc.???
5. Is there a difference in wiring that is abandoned (assuming that "abandoned" gets defined) that is energized and wiring that is not?
Separating unused wiring from this would make sense as there are many of us who believe that it may be used in the future. ( I was the kind of electrician that left many flexible conduits and feeders extra long for future remodeling, as i did so much of it ). There are too many conditions where future wiring is provided, unused, for whatever the future brings.
But the real issues involve damaged and hazardous wiring. All of Joe's pictures show damaged wiring, not abandoned or unused wiring. here are some of the questions that seem applicable to writing a blanket amendment to any of the codes.
1. damaged wiring may be hazardous, and hazardous may be damaged, but they are not the same. Is this article going to go after both groups, damaged and hazardous, or only when they occur together. If you want to argue that all damaged wiring is hazardous, go ahead as it is not self evident. Even where the damaged wiring poses some hazard to someone, there is a line between needing attention and needing immediate attention. Is the homeowners broken porch lite going to fall under the same rules as fallen distribution lines, energized metal in public ways?
2. are we not really talking about requiring repair or removal of the hazard, not the wiring.
3. doesthis not fall under already existing codes for the removal of public hazards. Most of the pictures shown depict wiring that needed repair, not removal.
Joe: are you really talking about the abatement of electrical hazards. I agree that this should be implemented in a sensible fashion, if it already has not been done, but not in the NEC.
