Bordew,
I've sent more than 1 e-mail to Ron Hazelton (the House Doctor), and to HGTV for his non-code, non safety conscious shows. Unfortunately, many DIY people watch these shows.
(I compare him to the other "Hazeldude", Joe Hazelwood, who got drunk and ran the Exxon Valdez up on a reef)

Bill,
Interesting point regarding the 3 switches. What about a split wired receptacle fed with 2 separate 2-conductor cables? Or, if you wanted to switch half a receptacle and ran out of 3-conductor cable, would it be a violation to run 2 separate 2-conductor cables?

I save instructions. I have before me a Nutone model 9427P, L,F,H. It shows a 3-function control with 2 separate 3-wires to the unit. There are 7 wirenuts shown in the unit's 'peckerhead' , or whatever it's called.
Note 3 ( out of 9) reads as follows;
Installatiuon work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction codes and standards

Sparky,
I know it's early in the morning, but..
If 2 separate 3-condoctor cables are shown, what do they show happening to the unused hot?

Redsy, regarding your question: if you wanted to switch half a receptacle and ran out of 3-conductor cable, would it be a violation to run 2 separate 2-conductor cables? As long as the neutral connecting tab on the receptacle was broken off and each cable had it's own neutral I don't see a problem with it. Do you? Bill

Sparky,
I can't figure what the 7 wirenuts are. Unless they are including one to cap the unused wire? I'm getting 6 wirenuts and 1 unused wire. Are you sure it's not a 4 function? (w/nightlight)
Fan Hot
Light Hot
Both Neutrals
Heat Hot
Heat Neutral
Both Grounds

Bill,
I don't see any problem, either. That is why I brought it up.
As far as the extra wirenut in the drawing, I also wonder about the other hot.

My question to Redsy, would be, why would you even run two, 2/c for a split receptacle ?
Second, 210-4(b), says that if this multi-wire goes to the same yoke there shall be a breaker tie, a 240 v circuit with a split recceptacle, and now there are two neutrals in parallel, which are smaller than no. 1/0.
Since it is a multi-wire circuit you would only need one neutral.

The neutrals aren't parallel because they have different loads? They would only be parallel if they were connected on both ends, right? (i.e. the tab "bridge" isn't removed)
I'm asking, not "telling" here...

Sparky66;
I would think that they would be regardless of the tab. First the circuit is a Edison 3-wire, one neutral. red and black going back to the panel to a 2-pole breaker or two single poles with a tie-lock, the tie-lock because they both go to the same strap or yoke.
By removing the tab, now you have 240 volts at the receptacles, since it is a duplex, with two seperate neutrals. Yeah you are right I dont think they would be parallel, but the problem if ther are two seperate breakers then that would create a problem of safty. and one breaker could be off misleading the electrician into thinking that the receptacle is dead when its still hot, thus the need for a 3/c with a tie-lock on the breaker and no split neutral. IMO thats asking for trouble.
