I am sure we have discussed this before...
I am of the opinion that 2 wire NM travelers for 3way & 4 way switching are not allowed by the NEC. I am hanging my hat on 300.3B. However, could 300.3B3 allow the use of 2 wire NM cable for 3 way systems? If so, was this a change from previous codes?
I have a contractor that did all 3 & 4 ways with 14-2 NM travelers. I red tagged citing 300.3B. I expect him to contest this, and he probably will argue that 300.3B3 allows this method. I do not believe that it does allow this, just looking for opinions/ reinforcement. I do not want to have him change this if somehow it meets minimum code.
Thanks
