Re: Old Unused Wiring
I think the new requirement is one that Joe Tedesco is trying to get passed into the 2005 NEC. Bear in mind that it has not passed and therefore is not a requirement.

Re: Old Unused Wiring
There are many NEC articles that require removal of abandoned wiring. But I believe they only apply to low-voltage systems, such as audio or TV cable. One example is 640.3(A).

Re: Old Unused Wiring
i think if it is properly safed off and marked for future use yuo will be ok. i will look for the reference and post later.

Re: Old Unused Wiring
I did some research regarding abandoned low voltage cables. There are code (2002 NEC) sections requiring the removal of accessible portions of abandoned cables from the ceiling. They are as follows:
1. Article 640.3 (A) ? Audio distribution cables
2. Article 725.2 (A) ? Remote control, signaling & power limited cables
3. Article 760.3 (A) ? Fire alarm cables
4. Article 770.3 (A) ? Fiber optic cables
5. Article 820.3 (A) ? Coaxial cables for CATV
6. Article 830.3 (A) ? Network communications cables (Cat 5, etc.)

Re: Old Unused Wiring
Note that if the conductors are tagged, they are no longer abandoned and they do not have to be removed. This is the biggest reason that I do not support the proposed code change. The only reason that this change should be accepted is if the abandoned wiring is creating a hazard. If this hazard can be mitigated by the simple act of placing tags on each end of the wire, there was never any real hazard.

Re: Old Unused Wiring
It is good practice to remove (or tag) abandoned (or future use) wiring.

Re: Old Unused Wiring
Wayne, I do not think wire tagging is a good idea , the reason I feel this way is who knows what the compentency of the person who put the tag on .
Also what if some one who was unqualified came along and energized this once abandonded wire ??
A lot of different hands can find their way into a system throughout time and who knows what one may be thinking and possibly do.
These ridiculous things "can and will" happen somewhere down the road, but the point I am trying to make is that a tag could give a false sense of presence and cause more harm than good to a unsuspecting person.

Re: Old Unused Wiring
as i understand it one of the reasons for requiring the removal of old cable is to reduce the fuel load, and more importantly the smoke- generating capacity, of materials in the plenum space. this goal is affected not at all by tagging unused wiring.
there's good money to be made at removing old wire, boys.

Re: Old Unused Wiring
BTW, i will never forget the old wiring in my parents' rental house in monrovia, ca. the prewar house had been renovated by what they call a handyman out there, and i found energized and unterminated wiring just laying in the wall space. very scary stuff.
