Yes it has a #6 white. It would not be called "6/3" if it did not have three #6.
I was just stating that because a previous poster mentioned if you were using NM that you could use #6 for the Ungrounded Conductors and #8 for the the Neutral and #10 for the Ground, evidently he didnt realize that #6 NM comes with a full size neutral not a #8.
I'm too industrial oriented and we always pull full size neutrals to any loads for the simple fact that the load it is serving today (although it may not require a full size neutral) may change tomorrow.
Today it may be feeding a 50 amp piece of equipment, Tomorrow it may be turned into a Subpanel to distribute power to some 120v Loads, and this just carries over for me when I do a residential install but like I said that's just me.
i dont really consider running pipe and pulling wire unless its for a Hot Tub or something like that when doing residential.
Otherwise I'll usually use NM.
