Thermostat wire needed

[Doug Miller]

Google is your friend... found this in about 30 seconds:

About $25 incl shipping for 30'. There are probably many other online retailers as well.

Go to an agricultural supply house. They sell 5 or 8 or 12 conductor wire for irrigation systems. They are for direct underground burial and 18 gauge solid.

The ones I have tried want to sell me the whole 250 ft. spool. I only need

30 ft.

Okay.

The humidistat is 2 wire. The thermostat is 4 wire (unless it's a heat pump). The humidifiers I've run use 2 wire with a dedicated transformer.

Does your system have a combo humidistat/thermostat?

And resistance varies inversely with the square of the conductor diameter.

And to the length of the wire. Further, the constant of proportionality is different for different sizes of wire.

"Dan C" claimed that the resistances of 18- and 24-ga conductors are identical. That is patently false.

I had googled many companies. Most all I found wanted to sell the 250' spool. Only one was willing to sell 30' and they wanted $10 extra for orders under $50.

So THANKS TO DOUG MILLER for that find. I have ordered my wire.
