About this app

This is a republishing of Electrician Bible application, and the reason is that due to natural disaster I lost my developing computer with all the information on it. For that reason I cannot upload more software update to the existing (Electrician Bible) in Google play store.
We apologize for any inconvenience that this may have caused.

You must be in android version 4.0 Ice Cream Sandwich or greater, and have an internet connection on your device.

A must have utility for electrician's, electrical contractors or those looking to pass an electrical certification.

Ratings and reviews

I've been a commercial/industrial electrician since 1987. Back in the day we had "UGLYS" pocket reference book. It was, and still is, an excellent reference guide. Now we have the Electricians Bible. This app is irreplaceable, it's at your fingertips always. I've recommended it to countless others in the trade. It's worth the one time fee. It's updated periodically. I'd miss it greatly if I were without it. THANKS TO ITS CREATORS.

love the app, and hopefully there's new updates...and improvements....new calculations...

Frustrating app. I don't know who designed this app, but it's trash. Will not do basic functions without you having to do backwards math to get the answer you need. I wanted to know what wire size I needed for a 20A circuit with derated for 10 current carrying conductors. It will not do it, it doesn't know how. All it gives me is that the circuit is derated to 10 amps and you need 14ga wire. This app is stupid.

What’s new

Updated ampacity calculations for improved NEC 2023 accuracy.
Improved conductor sizing when temperature correction and adjustment factors are applied.
Fixed rooftop temperature adjustment behavior, including the XHHW-2 exception.
Improved report accuracy and error handling for unsupported conductor sizes.
General bug fixes and stability improvements.
