E-Calc Pro is a professional electrical application for calculating many common electrical problems. This app is an essential tool for all electricians and electrical engineers. Unlike other similar apps E-Calc not only calculates simple formulas but returns code results including wire sizing, conduit sizing, fusing, overload size, ground and bond size and much more based on the Canadian Electric Code. The features of this app are too long to list but here are a few of the key ones;

- Basic construction calculator allows you to easily divide rooms for lighting in imperial or metric measurements.

- Calculate any single motor or multiple motor load and get maximum overcurrent, maximum overload, minimum wire, minimum pipe, and minimum bond wire size. Store a schedule of motors for easy retrieval.

- Calculate any transformer size and get KVA, FLA, pipe size, fuse and breaker size, bond size and ground size, on both primary and secondary. Easily choke down the transformer and get appropriate results for the modified demand load.

- Calculate feeders for wire size, conduit size and voltage drop simultaneously.

- Create panel legends of any size and easily export or print them right from your device.

- Calculate the allowable ampacity of any wire type and deration situation.

- Calculate maximum number of similar sized wires in a given pipe size.

- Calculate pipe size required for a list of any number, size, and type of wire.

- Calculate required ground and bonding sizes.

- Easily calculate complicated voltage drop calculations. Get results for percentage voltage drop as well as maximum lengths of runs and wire size. Derating is also supported.

- Calculate minimum burial depths for any situation including special situations including mechanical protection, under slab, and rock encased.

- Calculate any box fill situation in mL and cubic inch.

- Calculate recommeneded torque settings for all varieties of lugs and terminations.

- Convert many common units.

- Find NEMA codes and specs of receptacles.

- Calculate residential single dwelling service sizes.

- Easily access in app support with quick links to your tablets email.

Pros and cons of Electrical Calc app for iPhone and iPad

Electrical Calc app good for

Awesome app! Use it all the time for work. App support is fantastic to, had a problem and they had a fix right away!!!
This is a very useful app and would pay for it again. Should be in every sparkys tool kit.
Best electrical app out there. Code references and help are great.
Its extremely useful and easy to use. I just bought it and have used it for only a day but my impressions are very positive. I hope to see continued support of the app at this price but Im also more than happy to pay for quality.
Super helpful tool, every electrician should have it, it is so quick and easy to use. Thanks
What a great app. So much information at your finger tips. Would love to see demand load factor calculator in future up dates.

Some bad moments

Unless i was missing something most of the things i tried were way out to lunch from what the code book says
Very disappointed . I am an electrician here in quebec and this app does not follow the electrical code here in quebec ! For example #12 AWG wire in this app is good for 25 amps where as here in quebec is only good for 20 amps !! Also the colour code in this app is black red blue where as here it is red then black then blue !!! You guys should make an update that allows people to chose there province therefore being able to follow that code !!! Very disappointed i spent 10$ on this and unless there is some kind of update for this i would like a refund !
This app has a lot of helpful calculations with motors, transformers, burial depths and such. Great tool for any electrician to have. Would be nice to see more electrical conversions in the conversions section. Amps to miliamps, farads to microfarads, things like that would be more helpful.
