This sort of thing is usually an adapter, a little cylinder with a L6-20R on one end and a L6-30P on the other, since the loads are safe. Either that, or a short jumper cable wired the same way.
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. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
