Look at the last column in Table 400.4Is SO cable more durable than SJ type?
Pretty certain the J stands for junior.Always used type SO because it is far superior and rated for 600 volts while SJ ( always called it junior cord ) is only rated for 300 volts ). My cheap boss made my day along with a day of easy overtime when he saved money by purchasing a 250' roll of 16/4 SJO cord rather then the SO cord I asked for. It was for temporary power for portable conveyors that had 480 volt Manuel starters on them. Cheap SJO cord is only rated for 300 volts.
