There is no diagram.  It doesn't matter which goes where.  Just pick your favorite direction (left or right) and hook your favorite polarity up to it.

I need to find a wiring diagram for the EP-300-US tranformer I have.  On the wiring blocks, for both the line and low voltage, which terminals are neutral and which are the hot?

Too many things could cause that to happen, to effectively troubleshoot it through this forum.

If you could call 1-877-783-7832 we could run through all these possibilities and solve your problem much more quickly.  Just ask for Tim.

FIRST ELEMENT WARMS, 2ND AND 3RD DO NOT, BUT 4TH, 5TH, AND 6TH DO. OBVIESTLY THE CONNECTIONS ARE GOOD. WHAT COULD CAUSE THIS??

The point of the tinned copper wire is corrosion resistance.  Plain copper wire would corrode and likely cause the system to fail over time.

It's also important because using anything other than tinned copper voids the system's warranty.

What is the significance of the tinned straneded copper wire?

Is it more conductive?  If so, why not just use a larger stranded copper?

Provided it's all put together correctly, that preperation may be ideal.  And I'd pass on the thinset unless you're using it to set tile in.  Frankly, I'd recommend you consult a local carpenter who could look at your basement and make recomendations that way.

I am putting warmfloor in my daylight basement in Montana.  80023 is the project number for Ductmasters.   

Will there be any problem with putting a plastic sheeting vapor barrier, 1/2" of extruded polystyrene with 1/4 of particle board under the elements? 

We will be carpeting over it, and the warmfloor is supplemental heat for the basement. 

The other thought i had was doing thin set mortar over the top of the elements, but i am afraid this will make the floor feel hard.

The diagrams show putting the insulating and element layers together, but i read in another post that putting the elements on a plywood layer is ok.

If i left anything out please let me know,

Eric,

Unfortunately, I cannot answer your question, as installations of this nature vary depending on where you live.  In many instances, a conduit is not needed.  A proper (and inspector-friendly) installation is to be made in accordance to local codes and ordinances. These codes may require special wiring or a conduit (plastic or metal) in the walls.

I am installing a heating system for a large entertainment area in my basement.  For convenience, I would like to locate the transformers in a utility room.  The wiring run from transformers to terminal boards is approx. 28 ft.  Installation instructions say to use #6 wire for this distance.

I have #6 THHN wire.  Does this wire need to be in conduit, if it runs through enclosed wall?

If so, are there limitations on size and type of conduit for this application?
