As for a heavy duty Spec Grade or Hospital Grade Hubbell, they are built like a tank when compared to a Commercial Grade AC plug. True Audio Grade AC outlets include a more rigid plastic body and face that sometimes involves a fiber-reinforced polymer and dielectric dissipation materials which contributes to better electrical, rigidity and resonance control; heavy duty, larger mass conductive contacts that contribute to better conductivity and resonance control; a high-mass solid brass backstrap for greater rigidity and resonance control. A true Audio Grade AC outlet must perform a big step further than ordinary AC outlets.
Apples and oranges. I never said the Hubbell HBL5362 Extra Heavy Duty Industrial Series duplex receptacle was an Hi-end audio grade outlet.
As for an audio grade duplex receptacle's durability under pressure compared to the HBL5362 it would be interesting to install one in an industrial plant and see how it holds up to the everyday abuse it would be subjected to. It would be interesting to see how the male plug blade to female contact holding pressure of the receptacle holds up after just a few years of service, let alone 40 years. Plugging a plug straight in and pulling it straight out is one thing. Applying excessive side to side pressure to the female contacts of a receptacle is quite another.
Best regards,

Since most if not all major manufacturers make a 5362 (and its variants), any idea where this (and other) numbers came from?
I actually called up Leviton one time about this, and the kid who answered was completely lost, and said something about the marketing department.

I am not really sure. I think it has something to do with NEMA, ANSI, and UL standards.I did a web search for, what is a NEMA 5362 receptacle and here is what I found.

I even found Cooper.Cooper makes a heavy duty 5362 duplex receptacle under their Arrow Hart brand name. See page 7 of the link below.

Hi jea48,
Sorry, I'm being misunderstood in this thread. I should not have written "jea48 wrote:" at the beginning of the message.
I didn't mean to direct anything towards you, I simply responded to what cruzeFIRST said, then added my comment about Audio Grade AC outlets.
I reckon there is an industry standard that dictates what can be called an Extra Heavy Duty Industrial AC outlet, perhaps in the same manner as what can be called a Hospital Grade AC outlet. This might involve actual stress tests, including severe mechanical force stress tests.
Cheers, Duster

There is, on both counts, in addition to the capacity testing for voltage & current.
