Wiring for a Whole House Fan
[ad#block]Question: I am installing a whole house fan that runs on 120v (250 watts max).

The fan comes with 2 grounded plugs (1 to fan, one to damper system) to simply plug into an existing outlet in the attic.
I have heard that the NEC says that an appliance must be hardwired in an attic, not just plugged in, but that seems odd considering the low amps for this unit.
Can a permanent appliance be plugged in or does it need to be hardwired?

Dave’s Reply:
Thanks for your electrical question Nicole.
Nicloe, the designation of the whole house fan would be permanent, therefore a permanent electrical wiring would be required regardless of the circuit amperage.
