T310.16 Calculator checked against WireGuide 2005
WireGuide 2005 sells for $199 and is sold by Vision Infosoft. I found several problems with their program.
I downloaded the trial version to check it out against my own program written in JavaScript.
I found these problems so far.
WireGuide 2005 Service/Feeder Calculations
1. 20 ampere and 9 conductors input lists No. 12, rated 14 amperes on 20 ampere OCPD
2. 25 ampere and 3 conductors input lists No. 12, rated 25 amperes on 25 ampere OCPD (No. 12 is not allowed on a 25 ampere OCPD without exceptions)
3. 31 ampere and 6 conductors input lists No. 10 rated 24 amperes on 35 ampere OCPD
4. Only 75 degree C. insulation and terminal temperatures supported. (derating using 90 degree insulation ampacities is not allowed but is a common practice)
5. No provisions for continuous load and noncontinuous load inputs.
6. Only copper donductors are supported.
In my opinion, WireGuide 2005 is not NEC compliant and a warning should be attached to let users know.

To clarify, Vision InfoSoft does not sell a product called WireGuide 2005. Vision InfoSoft's electrical calculations software is called Electrical Calculation Manager (ECM). The current ECM is only NEC 1999 compliant. We are preparing a release of ECM that is fully NEC 2005 compliant. In invite you to check back at our website after January 2, 2007 for the latest information and to download a demo.
Again, WireGuide 2005 is not a Vision InfoSoft software product.

Your right Zoltek Software sells Wire Guide 2005. I had to go into the help files to find this since both yours and their programs expired.
Evidently, Zoltek and Vision Infosoft have some ties that have not been severed, because the ECM 99 software sold by Vision Soft has a help menu that has about and version information attributing the software to Zoltek.
Here is the info under the developed by menu item:
