Just replacing an L6-20P with an L6-30P on a 20A-listed PDU would be unsafe and (IMO) unwise, since the breaker in the input of the PDU does not protect the flexible cord's conductors from internal overcurrent faults.
Yet an 18 awg PC power cable is perfectly safe when plugged in to a 5-20R on a circuit with a 20 amp breaker. Get real man. You got two things right: The NEC (and related fire codes) don't apply to supply cords of appliances in circumstances such as OP's PDU. The modification cancels the UL certification. If you have an external requirement to use only UL certified components then you can't make any modifications no matter how obviously safe they are. By the way, you either don't have that requirement or you're breaking it. Your custom network cables are not UL certified. Regards, Bill Herrin -- William D.
