    Soooo NEC are you saying it is like Jack's diagram except the power for the lights comes through the 2nd switch? I'm just trying to simplify it yet do it properly. I'm trying not to confuse myself here

    The white wire from the second switch that is connected to the black wire from switch 1 needs to be permanently marked to indicate it is not a grounded conductor. This can be done with a permanent marker, heat shrink tubing, or label. It must be done on both ends. See NEC 200.7 (c) (2) below.

    But it must be the supply and not a return or a switch leg which is a return.

    That means it can only be used for the hot suppling a switch.

    Wanna argue the NEC? Game on my friend.

    Hit me with the code when you get a chance. As I read it the white and red wires are the supplies to switch 2.

    And explain to me how you would wire up 2 3-ways and a light if the power is to the light box rather than the switch without using the remarked white on one as a travelers.

    "Hit me with the code when you get a chance. As I read it the white and red wires are the supplies to switch 2."

    You gave the code.

    At that point they become switch legs and are switched on and off. Returns.

    Just idenify the white as a hot to the three way. Reidentify the hot to the second three way.

    "Just idenify the white as a hot to the three way. Reidentify the hot to the second three way. "

    I don't think so that would end up with 2 white wires going to the light and I believe that is a no-no. The hot goes to switch 1 and the common on switch 2 is a return not a hot supply.

    If you will notice in both the drawings Canuk supplied the remarked white is connected to the black traveler form switch one and is a traveler to switch 2 just as in my drawing.

    It also says "Tip: The traveller wire is connected in the light ceiling boxes, with a length of neutral wire taped black to indicate a hot wire. "

    Your own link to code is what it is. Reidentify as a hot or fail code compliance.
