If you try to use them for SJO wire, it will not work with number 10. Number 10 service cord SJOo wire, which you can get at Home Depot or Lowes will be PG13Point, sorry I think it's .3 or .5. In any case, those pages 21 would be more like wire number eight or wire number six. If you are also looking for an alternative to 13.5, the 16 will do for the number 10 serve, they just can't match the water resistance.
