1.0 out of 5 stars Hazardous design, terrible quality, January 5, 2010

This plug is DANGEROUS!
I am an electrical engineer and I am very careful with electrical devices. The contacts on this plug are terribly designed. They are not well held inside the plastic housing. The screws are way too close to each other and can short out. Also, the contact mounting plate has too much of a gap and can't hold stranded cable wire! The wire will most likely not be retained by the contact screws and may short out and cause FIRE!
The cable has no good way of being held by the shell and will most likely be held only by the contact screws which have the above described problem. I don't know how anyone can make this plug work safely.
Hubbell HBL9337C NEMA 10-30P AC Plug may be a better product but I haven't seen it in any of the stores. Stores in my area appear to be carrying only LEVITON. Does Leviton have monopoly?
