I’m upgrading my emergency backup generator so I recently got a 50 amp generator connection box. I still wanted to be able to use my older 30 amp rated generator, so this cable allows that connection from 50 amp box to 30 amp generator connector. It comes with a locking ring and a ring adapter/extender. It appears well made.
