Version 4.0 now includes calculations for aerial systems including:
All calculations are in
accordance with the industry accepted Neher-McGrath calculation procedures.
The Code tables for medium voltage cables as
well as many of the
tables for 0-2000 Volt Cable utilize the Neher-McGrath calculations
procedures. Unfortunately, the often utilized Tables 310.16 and 310.17
are not based on Neher-McGrath, but on research performed in the 1930's and for many
applications are very conservative.
AmpCalc Version 4.0 allows more suitable ampacity
ratings to be calculated for the applications covered by Tables 310.16 and
310.17, in addition to applications covered by other tables.
