Range Calculator now Online

It is 167K and about 4000 lines of code and appears to do the job of finding demand loads for up to 1000 ranges and more. It was a humdinger to write, but after breaking it down into doing just what the NEC does and not trying to make an all in one program it became easier. It has 9 examples taken from books, NEC, and some of my own. It is under the calculator menu or go to:

Range Calculator status report

I am continuing work on this calculator. There appears to be some holes in the NEC application rules for Table 220.55. For instance, what do we do with ranges, cooktops, and ovens when they are supplied by the same feeder or service and they vary in values from about 3 KW to 27 KW of unequal ratings? This project is attempting to find the feeder or service load for up to 1000 ranges, ovens, and cooktops including any combination of these for ratings of 1 3/4 KW to 27 KW allowing up to 10 unequal ratings. The input is by mouse selections using 0.1 increment values for KW. A separate calculator is being created for branch circuits.
