    E Rating

    So the "E" is just assigned to that rating with no origin of significance. Thanks for the info on ANSI alehman. I'll take a look. Hopefully, I'll find a good definition. SK

    E Rating

    Does anyone know the origin of the "E" in E Rating? I know Edison invented the first safety fuse, but I don't think the E was established from his name. I don't have the NEMA spec to see if they specify. Thanks, SK
