Maybe I'm just getting old but wasn't there a rule about mixing GFCI and non GFCI circuits in the same conduit? I know I have been flagged in the past but I can not find it anywhere in the Code. Is this just one of urban legends in our trade or am I just missing it. Thanks Paul

The only place I know of that prohibits mixing GFCI and non GFCI circuits is in Article 680 for pools and spas.

The problem with this article is that #3 allows mixing if they are suppling a feed through GFCI. That seems to contradict the meaning of this section. And it only applies to pool lights which is even stranger. My thought on this is if the wiring was to fault the other conductors could be energized by a non GFCI circuit. If you are in a pool that couldn't be good.

how are you going to supply a gfci device and not mix the two. The problem is people read the first line of the code article and think it is gospel. There are exceptions to almost every rule in the NEC

I generally always come out of the pool light box with a whip for the required conv. GFCI, but I always just use GFCI breakers for the pool lights and conv. receptacle.
