Neher-McGrath Calculations

[wareagle]

Can anyone direct me to a low cost program that will do NM
Caculation for cable capacity in conduit runs.
I had a demo from M.C. Group Engineering Inc. but I can not find their web site anylonger. May be out of business.

It's been around for awhile, but I have no experience. Other big analysis packages such as EDSA and SKM also claim to do N-M calcs, but these would be much more expensive, unless you needed the additional features.

for: a sample calculation done in the Excel spreadsheet. This will probably be least expensive approach
