SEU dimensions
Nominal calculation, not one manufacturer's datasheet. The conductors are compact aluminium as Southwire prints them; the XLPE walls are Southwire's, the neutral's wire count is Priority Wire's, and the jacket is fitted to six makers' diameters, because UL 854 was not read. Check the datasheet before you specify or order.
Each row is one SEU 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 SEU means, letter by letter.
