NMD90 dimensions
Nominal calculation, not one manufacturer's datasheet. The conductors are NEC Chapter 9 Table 8; the insulation, nylon and jacket walls and the bond are the values the makers print, because CSA C22.2 No. 48 was not read. Check the datasheet before you specify or order.
Each row is one NMD90 size in copper at 600 V: the conductor from NEC Table 8, the walls as the makers catalogue them. Open a row for every layer and its source. What NMD90 means, letter by letter.
