Well with all this talk of chicks hatching my envying stuck up chicken brat came out and said HUH they got chicks i'm going to fix my Bator.

Well i've got a Brower top hatch love everything about it but the thermostat so with the talk about dimmers i thought i would just try to fix mine with the one i had bought to make a bater.
In the pic you will see the bottom i have the dimmer hooked up and the turner is running and the fan and the light is working it uses candlelabra bulbs.
My question is what do i do with the ground wire i have no idea what to do with it please help??

It's the green wire i'm pointing at
