Paul, Yes Don Cunningham mentioned that he bought some home receptacles with that type clamp. I have previously only seen them in industrial applications - they make very solid connections.
I had to grin a bit at the electrician that wired a new rental house for us (I was not permitted to do my own work because I would not live in it for a year) and I specified #12 wire for all the receptacles, thus preventing the use of the backstab holes. All the receptacles in my home are also #12 wire to keep the voltage drop down, and the screws are well tightened (I had to check the ones the XYL connected) 73, Don W3FPR On 2/16/2011 3:10 PM, Paul Christensen wrote: >> If the receptacles are wired using the "backstab" holes rather then >> having the wires secured under the screws, that is a possible cause... > Good point, Don.
