exactly what i was looking for, makes the app i was using look basic. One request i have is when using voltage drop would be to add previous cable values, i.e so we can do the whole circuit that uses didn't cake sizes and lengths.
Very good app. On operating current, I suggest it should not be one line, but many line calculating the overall load, instead of each feeder only. Ettore Gallina, no need to thank me, actually I thank you for your hard work. Keep up the good work. Salute to you. May I take this opportunity to ask permission to email you once I am not so busy.
Garbage used to work until they had an update now I lost my money that I paid for on the pro key and the developer blames it on Google I'll never use this app again...see, there you go... Seller blames Google without offering any solution to fix. Just wants your MONEY. Gready developer! .
Gladly paid for this tool. I don't deal with electronics (from parts point of view) on daily basis, but often enough for me to really use this helpful app. Thx so much!
As an electronics and electric motor repairman, I used this App greatly in many ways of my work in calculations and many more... Thank you.
Great App. If you work in tech, engineering, or commissioning of plant, essential to verify safety. Cable sizes, protection etc. Paul.
Excellent electric app. Note: the engineer also give almost immediate, well within days time feedback or responses. Im quite impressed !
purchased the pro key but unable to do lighting calculation. it is showing you have installed manually or not not suppoted site. Didn't received any pro key.
Very important tool in the life of an electrician. Much more importantly is the math formulas for calculations.
Very good apps so much helpful to my needs of calculations for the electronics and electrical. Thanks for the author .😀
Awesome Electrical contracting app, I use it all the time, it's regularly updated, great job!
Great app, just got it off school for electrical, this is very useful.
fantastic , wonderful app , save your time and give you good result needed , thanks so much
Very helpful in troubleshooting, maintenance and installations
Very usefull and stable. Thanks
This Aplication it's very useful to who's electric work. Thanks
One of the good application for those working in electrical engineering.
It's getting better all the Time with new update
Excellent app for any Electrician or Electrical Engineer/Contract worker, or a student learning electrical engineering.
Excellent app!!! I'm very satisfied with it
Very useful app... appreciating your hardwork👍
It is very handy at work place
Thanks very much.its working perfectly
very good app for us sparkys on site
Great and very useful app 👍
great app, use it every day
Very informative, Great App
very useful ref. of electrical
Great App. Thanks
Awesome app for electrical engineers / electricians to use on the fly!!! filled with lots of features to make an electrical minded person jump with joy while on the phone and on the go. May not replace truly professional calculation programs, but as a quick indicator for some simple calculations, i haven't seen anything better on the app store. AWESOME WORK MAN!!!
