This expansive app contains tools to help calculate complex results like motors, transformers, pipe/box fill, voltage drop and wire derating. It also helps with simpler everyday tasks like pot-light spacing, burial depths, bonding sizing, strap spacing, torque and MUCH more.


On top of all the code specific tools, Sparky’s CircKit also contains a code-of-the-day to keep your code knowledge fresh, a helpful built-in notes app to record data across the app, as well as an easy to use calculator with fraction support. Best of all… the notes and calculator are accessible ANYWHERE in the app!
