Issue #31 - Developments in Fault Current, Arc Flash Calculations and Labeling

Here at ARCAD INC, we are deeply thankful for your confidence and loyalty and extend to you our best wishes for a happy and healthy Canadian Thanksgiving Day. Peace, Joy and Love to You. We would also like to update you on the important developments and a SPECIAL offer we have for you.

ARCAD's Short Circuit Analytic version 1.0 (SCA V1.0) program voltage range has been extended down to 115V and up to 220,000V. Also, new voltage rating combo box has been added to cable data entry screen and maximum transformer KVA rating was increased to 20,000KVA. More information about the SCA V1.0 software for short circuit fault current calculations is available at

ARCAD's Arc Flash Analytic version 5.0 (AFA V5.0) arc flash analysis and labeling software has been updated to fully conform with new NFPA 70E year 2015 requirements for equipment labeling. The labels created using the modernized AFA V5.0 program are now containing all the information required by the new standard, namely:

* Nominal system voltage
* Arc flash boundary
* Available incident energy and the corresponding working distance
* Site-specific level of personal protective equipment (PPE)

More information about the AFA V5.0 software is available at

Both the AFA V5.0 and the SCA V1.0 software have also been code signed by use of a cryptographic hash confirming the software owner and warranting that the code has not been altered or corrupted since it was signed.
