Kit does the job. My electrician had no problem installing the critical part to prevent mains backfeed, but the part that goes over the switch to alert someone when the panel is off didn't match the dual 50-amp -switches. I think my substitute would be to write on the switch itself to make sure it's pretty obvious.
