I've done the math. It is impossible without more HP and RPM. 56,000 CFM is 4,583.67 linear feet per minute. X 60 \ 5280 = 52.087 miles per hour coming off the fan. That is a column of air, 5 1/2 feet in diameter being pushed 52 miles per hour. Stick your hand out the car at 52.1 miles per...

Triangle Engineering has some great fans for uses like you describe. https://trianglefans.com/

This unit is in the finished attic? First, the humidity has to be high enough in the air to be able to sweat out at the dew point. My first guess is that all the hot humid air in the house is rising into that area. Hot and humid air is lighter than cool dry air so it will rise. Second the...

from the photo it looks like it was sold with a grinder stand, and the switch was on the stand.

a 48" 475 RPM hanging fan, with enclosure (total width 56") at Triangle Engineering is only 19,460 CFM. Has 1 HP motor and weighs 271 lbs. Triangle Engieering has one model that is 54" and puts out 42,500 CFM. It sits on a pole and has a large yoke. Belt drive. 230V single phase, and 230V and...

what is the green wire going to? Is there a lug on the relay?

it would be nice if something worked. I have several pairs of wire cutters etc where the original coating slips when I use them. I'd love to recoat them but if one goes back to the early parts of this 11 year old thread, there are comments about how the retail dip falls apart in less than a year.

good timing to train the gopher to help you pull it :)

also - thinking about it. I am a child of the early 1950's and dealt with a lot of dad's tools / appliances / radios etc when they needed repair. I am not an electrician, but I was trained in electronics of that and later eras. That grinder is supposedly from 1963-64. It may have been a two...

I found this on a 397.19581. Yours is a 19571. Can't tell you if this will work but might compare. For sure someone has tampered with the wiring on that already with black and white and green all tied together. I would not be plugging it in without looking carefully at the wiring...

someone has already been into that wiring. This is a photo from online what the switch should look like.

how do they fail? In say a lightning strike do the short to ground, take the surge and cause the main breaker to pop? I assume that is the kind of protection they are offering instead of just removing any over voltage conditions.

Can the downspouts be moved to a better location that does drain? it might be easier to re-pitch gutters unless they are integral to the construction. Can you add essentially temporary speed bumps that channel the water away? Next choice is hire someone with a concrete saw to cut the asphalt...

he had an intermittent open. That would be how I would describe it. You can also have an intermittent short. A nail driven thru the romex when my house was built in 1979 created an intermittent short in the AC circuit that I did not find until the house was re-sided in 2003 or so. Periodically...

if it is a conditioned space you would want as much R value as possible within reason, and considering the climate you are in. You indicate AK, if you experience cold winters, a greater R value on a large door would slow heat loss, heat that you are paying for. However if you are burning wood...

those small vents are to allow any leaked natural gas to escape before it causes the big bang. They were never meant for cooling. If the garage is hotter than outdoors by 10 degrees early in the morning, sounds like there is a lot of heat soak, and additional insulation will help with that...

good work. You listened to suggestions and found the fault. :)

using your logic, It was an open circuit because no current was flowing at times. It was not a shortened circuit because when it was working the current was always taking the full path. At other times it was a corroded circuit which falls under a partially open circuit - like a cold solder or...

the eletrons will choose the shortest path. If you are the shorter path you will get shocked. Electons will share a path back as well, meaning if they have an option of 2 paths they will take both. If you are one of those paths, you will get shocked.

antifreeze also prevents electrolysis, which can kill an engine from the inside out.
