Left handed splices of conductors - Electrician Talk - Professional Electrical Contractors Forum

Joe Tedesco · 10-26-2009, 09:05 PM

Have you ever discovered any old work, or new work that had left handed splices?

How does he NEC treat this subject?

I've heard of left handed cigarettes, but I've never heard of a left handed splice.

Every year when I teach splicing to my new students I always get a few lefthand splices. Usually from the left handed students. Left handers don't do anything right anyway.

Don't the instructions included with wire connectors stipulate twisting the wire with a righthand twist. That being said brings up 110.3(B).

I've seen a few. I also thought that it is a violation as well.

Ima Hack · 10-26-2009, 09:26 PM

You mean the conductors are twisted together counter clockwise before installing a wire nut??

110.3(B) but I've never read anything not allowing left-handed splicing.

It's awkward for a left handed person to do and has to be acquired a little. I had an old JW point that out to me by having me try to twist a joint counterclockwise. Same difference for them doing it clockwise.

I've come across it twice in my 11 years in the trade. It is kinda weird when you come across it for the first time. I don't think the NEC says anything about it.
Heck, you could think of it as this: Wires twisted tight going to the left, and a tight wire-nut going to the right. No way that joint would ever get loose and fail (I don't do this but I'm just saying it's one way you could look at it).

Section 110.14(B) in the National Electrical Code, NFPA 70 or 70A does not prohibit left handed splices. They are permitted to be soldered splices, or the splice could be completed using a Buchanan's tool and splice cap crimp connectors.

Search the UL White book for "Wire Connector's."

Use of an ordinary "wire nut" on a LHS will be difficult or even impossible.

I have seen splices in a bottle, splices in a pill box, and splices made with duct tape!

Quite frankly, you could break Federal laws by trying to enforce right handed twisting of wire nuts by left handed people. This would be a civil rights case involving the Americans with Disabilities Act.

In 2008, effective January 1, 2009, the ADAAA broadened the interpretations and added to the ADA examples of "major life activities" including, but not limited to, "caring for oneself, performing manual tasks, seeing, hearing, eating, sleeping, walking, standing, lifting, bending, speaking, breathing, learning, reading, concentrating, thinking, communicating, and working" as well as the operation of several specified "major bodily functions".[4] The Act overturns a 1999 U.S. Supreme Court case which held that an employee was not disabled if the impairment could be corrected by mitigating measures; it specifically provides that such impairment must be determined without considering such ameliorative measures. Another court restriction overturned is the interpretation that an impairment that substantially limits one major life activity must also limit others to be considered a disability.[4]
The ADAAA will undoubtedly lead to broader coverage of impaired employees. The United States House Committee on Education and Labor states that the amendment "makes it absolutely clear that the ADA is intended to provide broad coverage to protect anyone who faces discrimination on the basis of disability."[10]

I have no employees.......

Don't worry as soon as you need seasonal help I'll be there. I am available between Nov-April, whenever it's flat or the wind is not cooperating.
