The loads aren't safe. You will have a 30-amp circuit breaker feeding
the L6-30R socket. The load and its wiring are only rated for 20 amps
so if there's an overload you will exceed the ampacity of the wiring
downstream of the L6-20P and the L6-20P itself.
Option 1: Change the breaker to 20A and change the receptacle to L6-20R.
Option 2: Buy a 30-amp rated PDU equipped with L6-30P plug.
