This program calculates the number of same size conductors using the .8 roundoff method. In the Auto Mode this program limits the fill to 40 per cent for over 2 conductors, 31 per cent for only two conductors, and 53 percent for one conductor. Note: THWN, THHN, and THWN-2 have the same areas. RHH, RHW, and RHW-2 without coverings and THW-2, THW, and THHW have the same areas. RH, RHH, RHW, and RHW-2 with covering have the same areas. (This program does not calculate for 3/8 inch FMC and LTFMC - Open Table 348.22 below) Enter conductor information starting at the top of the form. ALL AREAS ARE IN SQUARE INCHES.
