Tell me why

I have a residential job I wired. Hot comes into switch connects to 3 way dimmer, travelers to other location (about 15' away) to a regular switch then switch leg comes back and up to light. The situation, there is always 3.4v coming back on the traveler that should be off. Whats is happening?

That's normal as you often get voltage thru a dimmer even when it is off. Don't loose sleep over it.

what kind of meter are you using? like dennis said thats probably the case but if you ever work on regular 3 ways and get a voltage on the dead traveler you are more than likely using a high impedance meter and seeing phantom voltage. use a wiggy or the loz function of a DMM

What's That?

Which one? This covers both.

In electronics, capacitive coupling is the transfer of energy within an electrical network by means of the capacitance between circuit nodes. This coupling can have an intentional or accidental effect. Capacitive coupling is typically achieved by placing a capacitor in series with the signal to be coupled.

What every one said plus, dose the dimmer have a small light to illuminate the switch?

 

[laketime]

yes the dimmer does have a small light.

Not a Lutron Maestro is it?

Jeopardy question:

"What do you call a wife who insists on having the best dimmers?"

Jeopard answer: (answer should be)

"What do you call a wife who insists on having the best dimmers?"

On Jeopardy the answer is the form of the question. The original name of the show was 'Whats the Question?'

Anyway - the back light is in series with the load when off... And Maestro the blue terminal is an electronic control wire...

Right. Alex gives the answer, then the contestant responds with the question. What's wrong how I said it?

Nothing, you executed the joke as well as you could have.
