Quick and useful
I’ve used this app for many projects over the years. Love that it has AC and DC options. Used it for regular line voltage, but also solar 400v dc, battery storage 48v dc and automotive 12v dc.
Great Quick Reference
I use this app so often. It is a great reference tool.
Motor starting Voltage drop
Motors have minimum starting voltage drop to 90% of the motors nameplate voltage. The program does not allow inputting a starting current to calculate the starting Voltage drop.
Quick and Easy!
This is a great field use tool to figure out wire size on the fly!
A must have app for electricians
I use this app for my job as an industrial electrician. It works great! It is a time saver.
Love These
It’s good. Thanks to Southwire for allowing me such generous computing capabilities on my iPhone. Five stars earned.
Electrical Engineer
I use every day in the field.

Safer
Nice to have this
Much safer then trying to remember or look up to fine the correct information and it’s right on my phone
Thank you for offering this
By the way your wire is all that I will use

Useful
Nice to be able to sit on the site and run the various options to figure out what size cable to run
Handy
The app was easy to use and it comes in handy on a job site
Useless!
Stalls at picking residential or commercial.

The app simply does not work. The screen is mostly locked. The only part that works is the review.

Confused
Wording is not deliberate enough and confusing when translating the end result. It should be just as simple as telling you the ampacity rating of a single wire after plugging in your distance, wire gauge, wire type, and which ambient temperature chart you will be using based on the NEC. Listing if it’s single or three phase and voltage inputs May or may not be important but if so then keep them. Don’t ask me to give you the amperage because your calculator should do that, it gets confusing if it’s asking me my overall intended amperage or the actual max amperage rating of the wire per NEC. For example- input your ambient temperature rating which most of us use the 75°C for most common applications. So if 10 awg THHN is rated at 35 amps at 75°C then I would expect the Calculator to read something like this- 75°C, 10 awg THHN (+ or x or whatever) at 200ft = 33 AMPS! So that just showed me that the ampacity rating just dropped by 2. That wasn’t a true equation of course, but I guess I was looking for something like that and then after giving the answer you could show the engineering breakdown for calculating the percentages or whatever and or maybe use tables that show you the decline of amperage at different footages? I’m not sure of the validity behind three-phase or single phase and maybe it is important but I would think a single wire by itself would have its own voltage drop after so many feet which would alter its ampcity rating?! But maybe it is important so just do the important stuff and then once you calculate that then maybe you have a Calculator to derate as these two calculations go hand and hand for sizing your wire (Circuit)

Bad app
So bad hard to use don’t give you a lot of options
Some times it just don’t work well like 50% of the time

calculator works as expected.
Bad
Doesn’t work correct. does not calculate for being a CALCULATOR. they need to address or fix so not download
