Definitely weird math some times. 3-Phase Power calculation appears to divide by pf vs multiply by pf in my version.
Would not work on my phone. Couldn't enter ampacity, and ground conductor directed me to shut down web sites.
Cannot read truncated words. Does not show numbers as typed in to calculator. Unusable.
Keeps work in the shop easy and efficient, also makes resolving wiring toubles allot easier (Certified automotive repair service
Wire amp sizes are wrong. 200 amp only needs a 2/0 size wire, not 250Kcmil. Do not trust this app!
Get over yourself the gov. can find you even if your gps is turned off, we live in a technological age, oh yeah the app is good
It's a very useful apps for electrical students & engineers. To calculate current, voltage
I have been an electrical contractor for many years. Great app saves time easy to use. Thanks for making it possible.
Allowed me to figure out how many watts my 240v heaters were using when they were only on 120v (hint, its not 1/2 because the resistance is constant).
Great app but the UI needs polishing. Keypad should auto-hide ones you click on the other fields.
Can't see the amps being entered. Clearing the last entered value not straight forward.
The app is good, but it would be excellent if it had support for metric wire sizes etc.
I'm a solar designer and this worked like a charm for a long dc run (120'). We'll see how it does for other purposes.
The grounding charts are gone...web page is gone...I hope they say they are making the change over to 2010 or fixing something...until then, its not worth having
#'s don't show n required amp box. Samsung Galaxy. Also have to escape to enter new calculation. All else good. Thanks for app.
I have looked at several calculators and this is the easiest to use and most convenient I've seen yet. Bravo!
Makes motor calcs simple and conductor sizing a snap.
Wish it had conduit fill calculator. What it does have works well.
Won't calcuate over 400 amps says out of nec range
We need a version in SI units
It is the best app for measurement current
Sweet wish i had this when i was in school
Has helpful info
120V, 200ft with 18AWG = voltage drop of 250V ???
Hey Gary STFU
Great apps thanks
Why does this need my gps?
The best!!!!
I entered One ampere for current and received a wire size of 2000 kcmil. Try changing insulation types to see this result. Some insulations give proper answers, some do not. edit: Seems any amperage of 13 or under returns a size of 2000 kcmil.......
