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.
Also some changes have been made to insure that the application comply with Google Play Terms of Service.
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.

    Best app ever. I have requested additional charts, formulas and they've always been right on top of it. I usually receive updates for my request 3 weeks to 2 months but they always find a way to get the info. These people are awesome for this app thank you
