I posted yesterday and then thought I had it figured so I edited post and thankfully, a moderator then deleted it. I apologize for making work for the moderators but now I have everything in order and I do have a question about running the ground from an attic fan.
The attic fan (Powercool Plus 15 by Air Vent Inc.) was installed by roofers when they did our roof many months ago. They installed the fan into the roof (nicely it appears) but sort of left me in a lurch re. wiring it up.
From the fan there is a thermostat/ humidistat. But that thermostat has only two wires running out of it for power - just the black (pos) and the white. There is a ground screw on the thermostat housing (obvious in green and marked as well on the install pdf, that I do, in fact, have). But the install doc is sparse about wiring.
At this point, I have simply purchased a 15A plug and I have wired the black from the thermostat to the brass side of plug and the white to the silver side. I ran this, for testing, to an available outlet in the attic and it appears to work ok. The fan is on and appears to be running well.
My question is about the ground, however. Shouldn't I ground this thing? Can I simply run a wire from the ground screw on the housing to the plug? It almost seems like the fan manufacturer doesn't think grounding is nec. because they didn't run a ground wire out of the housing. (Or do they want it grounded somewhere else? Again, the install literature from Air Vent gives no details about it).
Is it safe, good practice to run a wire from the ground screw to the plug ground terminal?
I guess what I'm asking is should I run ground to plug or somewhere else (house ground)?
Thanks in advance. I hope I have been clear enough. Best, Gary in VA
Ps. I have attached the install doc the roofers gave me.
