Comment on Handyman suggested cutting hole in 1330 sq. ft. attic for second attic ventilator. Does this make sense?
Yeah, that 240v line run suggestion puts a gigantic question mark on anything they’ve suggested at all.
240v for an attic fan? Wtf?
Yea, fire this “handyman”. 240 in the US is for high load devices, like AC, electric stove (electric heat is a direct short), electric water heater.
A fan draws a very small amount of current - less than 5 amps at 120v.
I have a small portable blower (this uses a compressor wheel, so draws more current than a fan), and it’s rated for 5 amps.
