Circuit drawing 3 way please comment

If the 3 ways were fed off of the Load side of the 2p Disconnect in the "Other Buiding" it still would'nt make any difference unless you were sure the 2p switch was off when you were working on the lighting circuit. you would have to make sure that the 2p Switch was clearly marked as the Main Disconnect. I dont like this type of install because nobody's going to think that the 2p switch is the main disconnect anyway.

I guess the real idea of "grouping" is what you would accept. One of course can immediately think of a two gang box with the switches under one cover plate. . .

But if I were installing this, I'd be inclined to do the install as drawn, with the 2-pole switch just below the threeway, say maybe two feet below, and in a location that is highly unlikely to be covered up by shelves or contents. My first favorite spot is beside the service door frame. I feel this satisfies "grouping", yet is a little more user friendly for the average HO who would be annoyed to have to figure out why all the outlets went dead.

I would accept your method as "grouped" if the switches were installed about 2 feet apart and one above the other next to the service door.

Thank you Sir.

They don't have to. :smile:

"Nobody's" going to work on the wiring except you, right, and you, as a NEC educated installer will look for the "disconnect".

(I'm gonna get slapped for that use of irony. . . :cool:)

I dont believe the 3way in this applications serves as an acceptable means of disconnect because its not disconnecting anything if someone flips the switch in the dwelling.

And that throws you right against 225.36 Exception again.

That adds an additional wire in the conduit between the buildings.

I kinda like the ability to disconnect the outlets and yet still have light, that I don't have to set up, to see to work on them.

Nothing says the disconnects, when used, have to all be off for any one of them to be considered off.

Sorry if I don't understand but I dont see it adding another wire if the three way is switching the neutral.

:-? "if the neutral is switching the neutral" :-?

I'm not sure what you meant my that, . . . . but here, consider:

I think that 480 is suggesting taking a hot from one of the "other building" 2-pole switch load terminals, and then running it to the "other building" threeway common terminal.

That puts the switched leg on the threeway common back at the house, which, to get to the "other building" luminaire has to run in a new conductor (not drawn) in the conduit between buildings.

---OR---

One could take a hot from one of the "other building" 2-pole switch load terminals, and then run it to the "house" threeway common terminal by adding a new conductor.

Bingo!

Now the 2-pole switch cuts off both the receps and lights.
 
If one were being really picky about being able to _force_ the light off no matter what someone does back at the house, I wouldn't add yet another wire to the conduit; I'd simply add another single pole switch in series with the 3-way set.

Now, does anyone remember the cute trick where with hot, neutral, and 2 additional switched wires you can switch two lights, one at the garage and one in the house? :)
