To clarify Hank’s post,  the circuit breaker panel is a “main lug only” configuration.  The incoming, from the xfer switch, is fed into a two pole 50A CB (MAIN) making the vertical buss bars energized.  The buddy plug is connected to the “Main lugs” and is protected by the two pole 50A CB as are all the other breakers.

An electrician’s jargon!
