Works great! I also purchased the Conntek ISI 80SS2-GYBX Temporary Generator Transfer Switch Power Inlet Box, 50 Amp (http://amzn.to/1MUrPBN) and would recommend that Power box as the cable fits perfectly. I've read some other reviewers who had issue with a different brand box not accepting the cable very easily. No need for any grease to get this cable to work with the Conntek box. It fits snugly but smoothly and is easy enough to lock into place without much trouble.
