Using neutral as a traveller on 3way switch

Re: Using neutral as a traveller on 3way switch

Wayne,

This was a "cut-and-paste" from an e-mail between Charles Miller and myself. The scenario Mr. Miller was referring to was from my original post (the 2nd one of this thread) where my 3-way circuit ran from switch box to lighting outlet to switch box. The white wire from the first switch box to the lighting outlet is NOT re-identified because it is the neutral. The white wire to the last switch box IS re-identified because it becomes a traveler. While it would make more sense to me to splice the red and black thru as travelers and re-identify that white as the RETURN from the switch, 200.7(C)(2) states that you cannot re-identify for that purpose. So my original post stands corrected.

Al,

You described my original post correctly but in my last post I stated that the correct way to do this (according to Mr. Miller and section 200.7(C)(2) ) is to splice the white wire to say the black incoming traveler at the lighting outlet and thereby re-identifying it as a traveler to the other 3-way switch making the black of that cable assembly the return to the lighting outlet.

Regards,

Phil

don_resqcapt19,
I just read 200.6 all the way and (B) says Sizes Larger than 6 AWG shall be identified either by a continuous whit or grey outer finish or by three continuous wh stripes on other than green insulation along it,s entire length or at the time of installation by distinctive white markings at it's terminations. This marking shall encircle the conductor or insulation.

I interpret this as, I have to change the color of the insulation completely and not just fold a piece of tape around the conductor but rather wrap the "tape" around the conductor where it enters the area of termination to the point of conection or to the device.

I am I reading this wrong???

justoys,
Yes, you are reading it wrong. You are not permitted to "field identify" a grounded conductor that is smaller than #4. 200.6(A) applies to conductors #6 and smaller and no reidentification is permitted. 200.6(B) applies to conductors #4 and larger. #4 and larger can be field identified by using "distinctive white marking at its terminations".
