In an effort to resolve a difference of opinnion could someone difinitively validate clarify the correct purpose for a diode being placed across a relay or soleniod coil.
Is it there to protect the coil from damage of the collapsing field;
Or is it there to protect circuit boards from the...
Is there any general standard rule fordetermining exhaust back pressure that states the amount pressure is increased for every elbow, 45 ect and lenght of pie distance.
Does anyone know where I can find a chart or spec's on how much back pressure is created by pipe diameters, elbows and 45's and 90 degree elbows. I'm trying to create an automatic calculator to provide both for my self and comrads at work to ensure gen set start ups are properly done.
Does anyone know where I could find a list of what circuit breakers are refered to such as a 52 device, 86 device 489 ect ect.
And what their purpose's are.
Does anyone know of an easy way to determine (in the field)a generators pitch. In other words How can I figure out what the pitch of an existing generator so I know what to order to put on line with an older unit for paralleling?
I'm starting to look into the possibilty of installing a solar panel aray to off set the rising cost of electric power. My current average monthly Kwh for a 30 day period runs about 2500 kwh. can anyone offer up any ideas for the size / (number of) panels and wattage that would be needed. And...
Can someone shed some light on the possible or real effect's of inductive loading of a PM generator set that is running with loads that have power factors from as low as .20 pf to .36pf on average. And whether or not this would be the most likely cause of regulators going bad every 30 to 45...
My water heater went up the other nite and I (having several women in the house) had to do something right then!
So I set out to obtain a replacement how ever at the time of night I was doing this the only thing I could come up with was a 85 gallon hot water heater (electric) which I bought and...
Can someone tell me why my cold water pressure is greater than my Hot water pressure as it comes from the spigot?
My tank switch is set at (off-60PSI) and has a differential pressure of (10 psi).
I've taken the hot water tank check valves out and inspected them for sticking or clogs but found...
Can someone tell me/or point me to a web site that I can get information on figureing out the proper size fuse for engine block heaters like those used on emergency generators.
Dose anyone know of any in-expensive device's that are small enough and for the most part accurate that can be affixed to the inside of well pipes for constant measurment of the height of water from the device to the water surface in the well in order for a computer to be connected to it for a...
Can anyone supply a vendor name or brand name or possibly a web site that can supply low cost device's which can be installed permanently in a well casing top for close measurement monitoring of standing water within a well?
Does anyone know of an inexpensive way to measure well water depth from the top of a well casing. Examples:the use of Infared; Ultrasonic; Radar
Something that is relatively accurate but not priced so as to render it an impossibilitie for a home owner to install?
I want to install a devise...
