tk12v

it looks like its 12v :(.

Mark we can try to determine which is hot without meter. it will just take few tries. do you want to do it?
Ask Your Own Electrical Question
Customer reply replied 4 years ago

sure... The meter gave a reading on one of the black from the top. All the whites are capped together


 

ok so lets assume that is hot. lets name that wire as black 1

the other 2 as black 2 and 3.

first lets try this. shut the breaker off. keep whites spliced. splice black 1 and black together. turn the breaker on and tell me which light comes on.

The traveler wire is hot... from the bottom of the box.

did you do what I asked to double check? or you are all set and do not need my help anymore?
Ask Your Own Electrical Question
Customer reply replied 4 years ago

I did connect wire black 1 to black 2 which are from the top of the box. No lights came on. Fussing with it ... which helped me see that the black from the bottom is hot. The two wires from the top are the lights. One for outside the door and one for the house floods. Knowing that ... how do I connect the z-wave three way switch and auxiliary switch.

yes but if you only have 3 black wires you do not have 3 way system. you have 2 single pole switches. where were you planning to install auxiliary switch?
Ask Your Own Electrical Question
Customer reply replied 4 years ago

I may have a misunderstanding of how this works and have several regular and aux switches so can make this work with what I have.


 


With that said, I wanted one switch for the porch and one for the flood which is what was installed (manual switches). I thought that you would need a z-wave three way and aux because there was a traveler between the manual switches.


 


Now that we know that the bottom wire is hot and the two wires on the top are for the porch and flood... not sure what I need to do?

we need 45609 do you have that? if yes how many and what color wires are coming out of it?
Ask Your Own Electrical Question
Customer reply replied 4 years ago

yes I have several 45609, but now confused as to how to hook it up.


 

Does it have one black (line ) one black (load ) one white (neutral ) and one ground wire coming out of it?
Ask Your Own Electrical Question
Customer reply replied 4 years ago

By the way... its gotta to be hard to not see what I see... thanks for hanging-on


 


Yes, the bottom (and each cable) has black, white, ground.

I meant coming out of the z wave.
Ask Your Own Electrical Question
Customer reply replied 4 years ago

The switches are like manual switches where the wires connect to them so no wires coming out

So It has screw terminals? If yes are the screw colors different?
Ask Your Own Electrical Question
Customer reply replied 4 years ago

yes, Terminals.. Load, line, Traveler, neutral.


 


All three of my cables have white caped together.


 


So... how do I take the one (bottom cable) and connect two zwave switches.. one to each of the (top cables). One switch for the porch and one for floods.

This is what we need to do. Add 2 white pig tails ( short piece of wire ) to the splice of white wires. Connect the other ends of each white pig tail to the neutral screw on each z wave switch.
Splice black coming from bottom together with 2 black pig tails. Connect each black pig tail to each Line screw of each z wave switch. Connect one black from top to Load screw on one z wave switch. Connect another black from top to another z wave switches load screw.

Let me know if you have more questions.
