Defective out of the box.
on January 15, 2014
The first time I attempted to plug in the matching Leviton 931 30/50 Amp, 250 Volt, Plug into this receptacle, the housing popped apart, rendering this item unusable. The two piece housing is held together, through the center, with a single rivet. The rivet pulled apart the first time I plugged in the plug. The internal terminals are held in the housing by a backplate, that is held by the rivet. Once the rivet loosens, the backplate gets pushed out along with the terminals whenever the plug terminals are pushed in. So, as is, the plug terminals could never fully seat in the receptacle terminals. But, even if it had stayed assembled, I still couldn't have used it as is. I purchased the "Preferred Industries MQ-B50-3 1-Gang Metal Box" that shows up on the item description page as being often purchased together. I would not recommend doing so. The receptacle is too long/deep for that box. When attempting to mount inside the box, the receptacle housing contacts the internal "Ground" mounting stud. Further, even if one turned the receptacle to an angle so that it cleared the stud, it still is too long to allow flush mounting of the receptacle plate to the box. The raised, rear threaded port of the box protrudes to deeply into the box to allow the receptacle to flush mount. So, I would advise not buying the two together. Given my poor impression of the matching plug, I'm not at all impressed by the Leviton brand, which as I understand was once counted among the best. Returning this item and going with a different brand.
