The receptacle is a NEMA 10-30 3-prong. I know not the voltage, but the electrician should be able to test it. I am having him install a new outlet. My concern is, if the 30AMP circuit currently has high enough voltage, are all PDUs derated to 24AMPs? If so, how would 24 AMPs be enough? Do they make 30AMP rated PDUs? What if I had the electrician install a 40AMP breaker? Would I need a higher AMP PDU? Sorry, but I am new to all of this and don't want to fry my investment, or my house.
